Exhibit 4.1

 

COMMON STOCK PURCHASE WARRANT

 

ROCK CREEK PHARMACEUTICALS, INC.

 

	Warrant Shares:	Initial Exercise Date: December 20, 2015

 

THIS COMMON STOCK PURCHASE
WARRANT (the “Warrant”) certifies that, for value received,                           
or its assigns (the “Holder”) is entitled, upon the terms and subject to the limitations on exercise and the
conditions hereinafter set forth, at any time on or after December 20, 2015 (the “Initial Exercise Date”) and
on or prior to the close of business on the five (5) year anniversary of the Initial Exercise Date (the “Termination
Date”) but not thereafter, to subscribe for and purchase from Rock Creek Pharmaceuticals, Inc., a Delaware corporation
(the “Company”), up to              shares (as subject
to adjustment hereunder, the “Warrant Shares”) of Common Stock. The purchase price of one share of Common Stock
under this Warrant shall be equal to the Exercise Price, as defined in Section 2(b).

 

Section 1.         Definitions.
Capitalized terms used and not otherwise defined herein shall have the meanings set forth in that certain Securities Purchase Agreement
(the “Purchase Agreement”), dated June 16, 2015 (the “Subscription Date”), among the Company
and the purchasers signatory thereto.

 

Section 2.          Exercise.

 

a)        Exercise of the
purchase rights represented by this Warrant may be made, in whole or in part, at any time or times on or after the Initial Exercise
Date and on or before the Termination Date by delivery to the Company (or such other office or agency of the Company as it may
designate by notice in writing to the registered Holder at the address of the Holder appearing on the books of the Company) of
a duly executed copy of the Notice of Exercise in the form annexed hereto by facsimile or email. Within three (3) Trading
Days following the date of exercise as aforesaid, the Holder shall deliver the aggregate Exercise Price for the shares specified
in the applicable Notice of Exercise by wire transfer or cashier’s check drawn on a United States bank unless the cashless
exercise procedure specified in Section 2(c) below is permitted and is specified in the applicable Notice of Exercise.
No ink-original Notice of Exercise shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization)
of any Notice of Exercise form be required.  Notwithstanding anything herein to the contrary, the Holder shall not be required
to physically surrender this Warrant to the Company until the Holder has purchased all of the Warrant Shares available hereunder
and the Warrant has been exercised in full, in which case, the Holder shall surrender this Warrant to the Company for cancellation
within three (3) Trading Days of the date the final Notice of Exercise is delivered to the Company. Partial exercises of this
Warrant resulting in purchases of a portion of the total number of Warrant Shares available hereunder shall have the effect of
lowering the outstanding number of Warrant Shares purchasable hereunder in an amount equal to the applicable number of Warrant
Shares purchased.  The Holder and the Company shall maintain records showing the number of Warrant Shares purchased and the
date of such purchases. The Company shall deliver any objection to any Notice of Exercise within one (1) Business Day of receipt
of such notice.  The Holder and any assignee, by acceptance of this Warrant, acknowledge and agree that, by reason
of the provisions of this paragraph, following the purchase of a portion of the Warrant Shares hereunder, the number of Warrant
Shares available for purchase hereunder at any given time may be less than the amount stated on the face hereof.

 

    	 

    	 

    

  

b)        Exercise Price.
The exercise price per share of the Common Stock under this Warrant shall be $2.83, subject to adjustment hereunder (the “Exercise
Price”).

 

c)        Cashless Exercise.
If at any time after the six (6) month anniversary of the Subscription Date, there is no effective Registration Statement
at the time of exercise hereof registering, or no current prospectus available for, the resale of the Warrant Shares by the Holder,
then this Warrant may also be exercised, in whole or in part, at such time by means of a “cashless exercise” in which
the Holder shall be entitled to receive a number of Warrant Shares equal to the quotient obtained by dividing [(A-B) (X)] by (A),
where:

 

(A) = the VWAP on the Trading Day
immediately preceding the date on which Holder elects to exercise this Warrant by means of a “cashless exercise,” as
set forth in the applicable Notice of Exercise;

 

(B) = the Exercise Price of this
Warrant, as adjusted hereunder; and

 

(X) = the number of Warrant Shares
that would be issuable upon exercise of this Warrant in accordance with the terms of this Warrant if such exercise were by means
of a cash exercise rather than a cashless exercise.

 

“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, 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. (New York City 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 OTC Markets, Inc. (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 Holders of a majority in interest of the Securities then outstanding and reasonably acceptable to
the Company, the fees and expenses of which shall be paid by the Company.

d)        Mechanics
of Exercise.

 

i.            Delivery
of Warrant Shares Upon Exercise. The Company shall cause the Warrant Shares purchased hereunder to be transmitted by the Transfer
Agent to the Holder by crediting the account of the Holder’s prime broker with The Depository Trust Company through its Deposit
or Withdrawal at Custodian system (“DWAC”) if the Company is then a participant in such system and either (A) there
is an effective registration statement permitting the issuance of the Warrant Shares to or resale of the Warrant Shares by Holder
or (B) this Warrant is being exercised via cashless exercise, and otherwise by physical delivery to the address specified
by the Holder in the Notice of Exercise by the date that is one (1) Trading Day after the delivery to the Company of the Notice
of Exercise (such date, the “Warrant Share Delivery Date”), provided that the Company shall not be obligated
to deliver Warrant Shares hereunder unless the Company has received the aggregate Exercise Price on or before the Warrant Share
Delivery Date.   The Warrant Shares shall be deemed to have been issued, and Holder or any other person so designated
to be named therein shall be deemed to have become a holder of record of such shares for all purposes, as of the date the Warrant
has been exercised, with payment to the Company of the Exercise Price (or by cashless exercise, if permitted) and all taxes required
to be paid by the Holder, if any, pursuant to Section 2(d)(vi) prior to the issuance of such shares, having been paid.
If the Company fails for any reason to deliver to the Holder the Warrant Shares subject to a Notice of Exercise by the Warrant
Share Delivery Date, the Company shall pay to the Holder, in cash, as liquidated damages and not as a penalty, for each $1,000
of Warrant Shares subject to such exercise (based on the VWAP of the Common Stock on the date of the applicable Notice of Exercise),
$10 per Trading Day for each Trading Day after such Warrant Share Delivery Date until such Warrant Shares are delivered or Holder
rescinds such exercise.  The obligation of the Company to pay liquidated damages under this Section 2(d)(i) is subject
to delivery by the Holder of the aggregate Exercise Price in accordance with the terms of Section 2(a) herein.

 

ii.         Delivery
of New Warrants Upon Exercise. If this Warrant shall have been exercised in part, the Company shall, at the request of a Holder
and upon surrender of this Warrant certificate, at the time of delivery of the Warrant Shares, deliver to the Holder a new Warrant
evidencing the rights of the Holder to purchase the unpurchased Warrant Shares called for by this Warrant, which new Warrant shall
in all other respects be identical with this Warrant.

 

iii.         Rescission
Rights. If the Company fails to cause the Transfer Agent to transmit to the Holder the Warrant Shares pursuant to Section 2(d)(i) by
the Warrant Share Delivery Date, then the Holder will have the right to rescind such exercise. The right of rescission of the Holder
under this Section 2(d)(iii) is subject to delivery by the Holder of the aggregate Exercise Price in accordance with
the terms of Section 2(a) herein

 

    	-3-

    	 

    

  

iv.         Compensation
for Buy-In on Failure to Timely Deliver Warrant Shares Upon Exercise. In addition to any other rights available to the Holder,
if the Company fails to cause the Transfer Agent to transmit to the Holder the Warrant Shares pursuant to an exercise on or before
the Warrant Share Delivery Date, and if after such date the Holder is required by its broker to purchase (in an open market transaction
or otherwise) or the Holder’s brokerage firm otherwise purchases, shares of Common Stock to deliver in satisfaction of a
sale by the Holder of the Warrant Shares which the Holder anticipated receiving upon such exercise (a “Buy-In”),
then the Company shall (A) pay in cash to the Holder the amount, if any, by which (x) the Holder’s total purchase
price (including brokerage commissions, if any) for the shares of Common Stock so purchased exceeds (y) the amount obtained
by multiplying (1) the number of Warrant Shares that the Company was required to deliver to the Holder in connection with
the exercise at issue times (2) the price at which the sell order giving rise to such purchase obligation was executed, and
(B) at the option of the Holder, either reinstate the portion of the Warrant and equivalent number of Warrant Shares for which
such exercise was not honored (in which case such exercise shall be deemed rescinded) or deliver to the Holder the number of shares
of Common Stock that would have been issued had the Company timely complied with its exercise and delivery obligations hereunder. 
For example, if the Holder purchases Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an
attempted exercise of shares of Common Stock with an aggregate sale price giving rise to such purchase obligation of $10,000, under
clause (A) of the immediately preceding sentence the Company shall be required to pay the Holder $1,000. The Holder shall
provide the Company written notice indicating the amounts payable to the Holder in respect of the Buy-In and, upon request of the
Company, evidence of the amount of such loss.  Nothing herein shall limit a Holder’s right to pursue any other remedies
available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive
relief with respect to the Company’s failure to timely deliver shares of Common Stock upon exercise of the Warrant as required
pursuant to the terms hereof. The obligation of the Company to pay compensation for Buy-In under this Section 2(d)(iv) is
subject to delivery by the Holder of the aggregate Exercise Price in accordance with the terms of Section 2(a) herein

 

v.           No
Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon the exercise
of this Warrant.  As to any fraction of a share which the 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 final fraction in an amount equal to such fraction
multiplied by the Exercise Price or round up to the next whole share.

 

vi.         Charges,
Taxes and Expenses. Issuance of Warrant Shares shall be made without charge to the Holder for any issue or transfer tax or
other incidental expense in respect of the issuance of such Warrant Shares, all of which taxes and expenses shall be paid by the
Company, and such Warrant Shares shall be issued in the name of the Holder or in such name or names as may be directed by the Holder; provided, however,
that in the event Warrant Shares are to be issued in a name other than the name of the Holder, this Warrant when surrendered for
exercise shall be accompanied by the Assignment Form attached hereto duly executed by the Holder and the Company may require,
as a condition thereto, the payment of a sum sufficient to reimburse it for any transfer tax incidental thereto.  The Company
shall pay all Transfer Agent fees required for same-day processing of any Notice of Exercise and all fees to the Depository Trust
Company (or another established clearing corporation performing similar functions) required for same-day electronic delivery of
the Warrant Shares.

 

vii.         Closing
of Books. The Company will not close its stockholder books or records in any manner which prevents the timely exercise of this
Warrant, pursuant to the terms hereof.

e)        Holder’s
Exercise Limitations. The Company shall not effect any exercise of this Warrant, and a Holder shall not have the right to exercise
any portion of this Warrant, pursuant to Section 2 or otherwise, to the extent that after giving effect to such issuance after
exercise as set forth on the applicable Notice of Exercise, the Holder (together with the Holder’s Affiliates, and any other
Persons acting as a group together with the Holder or any of the 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 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 (i) exercise of the remaining, nonexercised portion of this Warrant beneficially owned by the
Holder or any of its Affiliates and (ii) exercise or conversion of the unexercised or nonconverted portion of any other securities
of the Company (including, without limitation, any other  Common Stock Equivalents) subject to a limitation on conversion
or exercise analogous to the limitation contained herein beneficially owned by the Holder or any of its Affiliates.  Except
as set forth in the preceding sentence, for purposes of this Section 2(e), beneficial ownership shall be calculated in accordance
with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder, it being acknowledged
by the Holder that the Company is not representing to the Holder that such calculation is in compliance with Section 13(d) of
the Exchange Act and the Holder is solely responsible for any schedules required to be filed in accordance therewith.  
To the extent that the limitation contained in this Section 2(e) applies, the determination of whether this Warrant is
exercisable (in relation to other securities owned by the Holder together with any Affiliates) and of which portion of this Warrant
is exercisable shall be in the sole discretion of the Holder, and the submission of a Notice of Exercise shall be deemed to be
the Holder’s determination of whether this Warrant is exercisable (in relation to other securities owned by the Holder together
with any Affiliates) and of which portion of this Warrant is exercisable, in each case subject to the Beneficial Ownership Limitation,
and the Company shall have no obligation to verify or confirm the accuracy of such determination and shall have no liability for
exercises of the Warrant that are not in compliance with the Beneficial Ownership Limitation (other than to the extent that information
on the number of outstanding shares of Common Stock of the Company is provided by the Company and relied upon by the Holder).  
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 and the rules and regulations promulgated thereunder and the Company shall have no obligation to verify or
confirm the accuracy of such determination and shall have no liability for exercises of the Warrant that are not in compliance
with the Beneficial Ownership Limitation.  For purposes of this Section 2(e), in determining the number of outstanding
shares of Common Stock, a 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 filed with the Commission, as the case may be, (B) a more recent public announcement
by the Company or (C) a more recent written notice by the Company or the Transfer Agent setting forth the number of shares
of Common Stock outstanding.  Upon the written or oral request of a Holder, the Company shall within two Trading Days confirm
orally and in writing to the 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 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 Holder, upon not less than 61 days’ prior notice to the Company, may increase or decrease the Beneficial Ownership Limitation
provisions of this Section 2(e), provided that the Beneficial Ownership Limitation in no event exceeds 4.99% 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 Holder and the provisions of this Section 2(e) 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 paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 2(e) to
correct this paragraph (or any portion hereof) which may be defective or inconsistent with the intended Beneficial Ownership Limitation
herein contained or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitations
contained in this paragraph shall apply to a successor holder of this Warrant.

Section 3.          Certain
Adjustments.

 

a)        Subsequent
Issuances. The Exercise Price shall be adjusted from time to time as follows:

 

(i)          Adjustment
upon Issuance of shares of Common Stock. If and whenever on or after the Subscription Date and prior to the six (6) month anniversary
of the Subscription Date, the Company issues or sells, or in accordance with this Section 3 is deemed to have issued or sold, any
shares of Common Stock (including the issuance or sale of shares of Common Stock owned or held by or for the account of the Company,
but excluding shares of Common Stock deemed to have been issued by the Company in connection with any Excluded Securities (as defined
below) (the "Additional Shares") for a consideration per share (the "New Issuance Price") less
than a price (the "Applicable Price") equal to the Exercise Price in effect immediately prior to such issue or
sale or deemed issuance or sale (the foregoing a "Dilutive Issuance"), then immediately after such Dilutive Issuance,
the Exercise Price then in effect shall be reduced to the lowest price per share at which any share of Common Stock was issued
or sold or deemed to be issued or sold

 

For purposes
of determining the adjusted Exercise Price under this Section 3(a), the following shall be applicable:

 

(ii)        Issuance
of Options. If the Company in any manner grants any Options (as defined below) and the lowest price per share for which one
share of Common Stock is issuable upon the exercise of any such Option or upon conversion, exercise or exchange of any Convertible
Securities (as defined below) issuable upon exercise of any such Option is less than the Applicable Price, then such share of Common
Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the granting or sale of
such Option for such price per share. For purposes of this Section 3(a)(ii), the "lowest price per share for which one share
of Common Stock is issuable upon exercise of such Options or upon conversion, exercise or exchange of such Convertible Securities
issuable upon exercise of any such Option" shall be equal to the sum of the lowest amounts of consideration (if any) received
or receivable by the Company with respect to any one share of Common Stock upon the granting or sale of the Option, upon exercise
of the Option and upon conversion, exercise or exchange of any Convertible Security issuable upon exercise of such Option less
any consideration paid or payable by the Company with respect to such one share of Common Stock upon the granting or sale of such
Option, upon exercise of such Option and upon conversion exercise or exchange of any Convertible Security issuable upon exercise
of such Option. No further adjustment of the Exercise Price shall be made upon the actual issuance of such shares of Common Stock
or of such Convertible Securities upon the exercise of such Options or upon the actual issuance of such shares of Common Stock
upon conversion, exercise or exchange of such Convertible Securities.

 

    	-6-

    	 

    

  

(iii)        Issuance
of Convertible Securities. If the Company in any manner issues or sells any Convertible Securities and the lowest price per
share for which one share of Common Stock is issuable upon the conversion, exercise or exchange thereof is less than the Applicable
Price, then such share of Common Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the
time of the issuance or sale of such Convertible Securities for such price per share. For the purposes of this Section 3(a)(iii),
the "lowest price per share for which one share of Common Stock is issuable upon the conversion, exercise or exchange thereof"
shall be equal to the sum of the lowest amounts of consideration (if any) received or receivable by the Company with respect to
one share of Common Stock upon the issuance or sale of the Convertible Security and upon conversion, exercise or exchange of such
Convertible Security less any consideration paid or payable by the Company with respect to such one share of Common Stock upon
the issuance or sale of such Convertible Security and upon conversion, exercise or exchange of such Convertible Security. No further
adjustment of the Exercise Price or number of Warrant Shares shall be made upon the actual issuance of such shares of Common Stock
upon conversion, exercise or exchange of such Convertible Securities, and if any such issue or sale of such Convertible Securities
is made upon exercise of any Options for which adjustment of this Warrant has been or is to be made pursuant to other provisions
of this Section 3(a), no further adjustment of the Exercise Price shall be made by reason of such issue or sale.

 

(iv)        Change
in Option Price or Rate of Conversion. If the purchase price provided for in any Options, the additional consideration, if
any, payable upon the issue, conversion, exercise or exchange of any Convertible Securities, or the rate at which any Convertible
Securities are convertible into or exercisable or exchangeable for shares of Common Stock increases or decreases at any time,
the Exercise Price in effect at the time of such increase or decrease shall be adjusted to the Exercise Price which would have
been in effect at such time had such Options or Convertible Securities provided for such increased or decreased purchase price,
additional consideration or increased or decreased conversion rate, as the case may be, at the time initially granted, issued
or sold. For purposes of this Section 3(a)(iv), if the terms of any Option or Convertible Security that was outstanding as of
the date of issuance of this Warrant are increased or decreased in the manner described in the immediately preceding sentence,
then such Option or Convertible Security and the shares of Common Stock deemed issuable upon exercise, conversion or exchange
thereof shall be deemed to have been issued as of the date of such increase or decrease. No adjustment pursuant to this Section
3(a) shall be made if such adjustment would result in an increase of the Exercise Price then in effect.

 

    	-7-

    	 

    

  

(v)        Calculation
of Consideration Received. In case any Option is issued in connection with the issue or sale of other securities of the Company,
together comprising one integrated transaction, (x) the Options will be deemed to have been issued for the Option Value of such
Options and (y) the other securities issued or sold in such integrated transaction shall be deemed to have been issued for the
difference of (I) the aggregate consideration received by the Company less any consideration paid or payable by the Company pursuant
to the terms of such other securities of the Company, less (II) the Option Value. If any shares of Common Stock, Options or Convertible
Securities are issued or sold or deemed to have been issued or sold for cash, the consideration received therefor will be deemed
to be the net amount received by the Company therefor. If any shares of Common Stock, Options or Convertible Securities are issued
or sold for a consideration other than cash, the amount of such consideration received by the Company will be the fair value of
such consideration, except where such consideration consists of securities, in which case the amount of consideration received
by the Company will be the Closing Sale Price of such security on the date of receipt. If any shares of Common Stock, Options or
Convertible Securities are issued to the owners of the non-surviving entity in connection with any merger in which the Company
is the surviving entity, the amount of consideration therefor will be deemed to be the fair value of such portion of the net assets
and business of the non-surviving entity as is attributable to such shares of Common Stock, Options or Convertible Securities,
as the case may be. The fair value of any consideration other than cash or securities will be determined jointly by the Company
and the holder of a least a majority in interest of the number of Warrant Shares issuable upon exercise of the Warrants then outstanding
(the “Required Holders”). If such parties are unable to reach agreement within ten (10) days after the occurrence
of an event requiring valuation (the "Valuation Event"), the fair value of such consideration will be determined
within five (5) Trading Days after the tenth (10th) day following the Valuation Event by an independent, reputable appraiser jointly
selected by the Company and the Required Holders. The determination of such appraiser shall be final and binding upon all parties
absent manifest error and the fees and expenses of such appraiser shall be borne by the Company.

 

(v)        Record
Date. If the Company takes a record of the holders of shares of Common Stock for the purpose of entitling them (A) to receive
a dividend or other distribution payable in shares of Common Stock, Options or in Convertible Securities or (B) to subscribe for
or purchase shares of Common Stock, Options or Convertible Securities, then such record date will be deemed to be the date of the
issue or sale of the shares of Common Stock deemed to have been issued or sold upon the declaration of such dividend or the making
of such other distribution or the date of the granting of such right of subscription or purchase, as the case may be.

 

b)        Voluntary
Adjustment By Company. The Company may at any time during the term of this Warrant reduce the then current Exercise Price to
any amount and for any period of time deemed appropriate by the Board of Directors of the Company.

 

    	-8-

    	 

    

  

c)        Stock Dividends
and Splits. If the Company, at any time while this Warrant is outstanding: (i) pays a stock dividend or otherwise makes
a distribution or distributions on shares of its Common Stock or any other equity or equity equivalent securities payable in shares
of Common Stock (which, for avoidance of doubt, shall not include any shares of Common Stock issued by the Company upon exercise
of this Warrant), (ii) subdivides outstanding shares of Common Stock into a larger number of shares, (iii) combines (including
by way of reverse stock split) outstanding shares of Common Stock into a smaller number of shares, or (iv) issues by reclassification
of shares of the Common Stock any shares of capital stock of the Company, then in each case the Exercise Price shall be multiplied
by a fraction of which the numerator shall be the number of shares of Common Stock (excluding treasury shares, if any) outstanding
immediately before such event and of which the denominator shall be the number of shares of Common Stock outstanding immediately
after such event, and the number of shares issuable upon exercise of this Warrant shall be proportionately adjusted such that the
aggregate Exercise Price of this Warrant shall remain unchanged.  Any adjustment made pursuant to this Section 3(a) shall
become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution
and shall become effective immediately after the effective date in the case of a subdivision, combination or re-classification.

 

d)        Subsequent
Rights Offerings. In addition to any adjustments pursuant to Section 3(a) above, if at any time the Company grants,
issues or sells any Common Stock Equivalents or rights to purchase stock, warrants, securities or other property pro rata to the
record holders of any class of shares of Common Stock (the “Purchase Rights”), then the Holder will be entitled
to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired
if the Holder had held the number of shares of Common Stock acquirable upon complete exercise of this Warrant (without regard to
any limitations on exercise hereof, including without limitation, the Beneficial Ownership Limitation) immediately before the date
on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as
of which the record holders of shares of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights
(provided, however, to the extent that the Holder’s right to participate in any such Purchase Right would result in the Holder
exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate in such Purchase Right to such
extent (or beneficial ownership of such shares of Common Stock as a result of such Purchase Right to such extent) and such Purchase
Right to such extent shall be held in abeyance for the Holder until such time, if ever, as its right thereto would not result in
the Holder exceeding the Beneficial Ownership Limitation).

 

e)        Pro Rata Distributions.
During such time as this Warrant is outstanding, if the Company shall declare or make any dividend or other distribution of its
assets (or rights to acquire its assets) to holders of shares of Common Stock, by way of return of capital or otherwise (including,
without limitation, any distribution of cash, stock or other securities, property or options by way of a dividend, spin off, reclassification,
corporate rearrangement, scheme of arrangement or other similar transaction) (a “Distribution”), at any time
after the issuance of this Warrant, then, in each such case, the Holder shall be entitled to participate in such Distribution to
the same extent that the Holder would have participated therein if the Holder had held the number of shares of Common Stock acquirable
upon complete exercise of this Warrant (without regard to any limitations on exercise hereof, including without limitation, the
Beneficial Ownership Limitation) immediately before the date of which a record is taken for such Distribution, or, if no such record
is taken, the date as of which the record holders of shares of Common Stock are to be determined for the participation in such
Distribution (provided, however, to the extent that the Holder’s right to participate in any such Distribution
would result in the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate
in such Distribution to such extent (or in the beneficial ownership of any shares of Common Stock as a result of such Distribution
to such extent) and the portion of such Distribution shall be held in abeyance for the benefit of the Holder until such time, if
ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation). To the extent that this
Warrant has not been partially or completely exercised at the time of such Distribution, such portion of the Distribution shall
be held in abeyance for the benefit of the Holder until the Holder has exercised this Warrant.

f)         Fundamental
Transaction. If, at any time while this Warrant is outstanding, (i) the Company, directly or indirectly, in one or more
related transactions effects any merger or consolidation of the Company with or into another Person, (ii) the Company,
directly or indirectly, effects any sale, lease, license, assignment, transfer, conveyance or other disposition of
all or substantially all of its assets in one or a series of related transactions, (iii) any, direct or indirect, purchase
offer, tender offer or exchange offer (whether by the Company or another Person) is completed pursuant to which holders of Common
Stock are permitted to sell, tender or exchange their shares for other securities, cash or property and has been accepted by the
holders of 50% or more of the outstanding Common Stock, (iv) the Company, directly or indirectly, in one or more related transactions effects
any reclassification, reorganization or recapitalization of the Common Stock or any compulsory share exchange pursuant to which
the Common Stock is effectively converted into or exchanged for other securities, cash or property, or (v) the Company, directly
or indirectly, in one or more related transactions consummates a stock or share purchase agreement or other business combination
(including, without limitation, a reorganization, recapitalization, spin-off or scheme of arrangement) with another Person
or group of Persons whereby such other Person or group acquires more than 50% of the outstanding shares of Common Stock (not
including any shares of Common Stock held by the other Person or other Persons making or party to, or associated or affiliated
with the other Persons making or party to, such stock or share purchase agreement or other business combination) (each
a “Fundamental Transaction”), then, upon any subsequent exercise of this Warrant, the Holder shall have the
right to receive, for each Warrant Share that would have been issuable upon such exercise immediately prior to the occurrence of
such Fundamental Transaction, at the option of the Holder (without regard to any limitation in Section 2(e) on the exercise
of this Warrant), the number of shares of Common Stock of the successor or acquiring corporation or of the Company, if it is the
surviving corporation, and any additional consideration (the “Alternate Consideration”) receivable as a result
of such Fundamental Transaction by a holder of the number of shares of Common Stock for which this Warrant is exercisable immediately
prior to such Fundamental Transaction (without regard to any limitation in Section 2(e) on the exercise of this Warrant). 
For purposes of any such exercise, the determination of the Exercise Price shall be appropriately adjusted to apply to such Alternate
Consideration based on the amount of Alternate Consideration issuable in respect of one share of Common Stock in such Fundamental
Transaction, and the Company shall apportion the Exercise Price among the Alternate Consideration in a reasonable manner reflecting
the relative value of any different components of the Alternate Consideration.  If holders of Common Stock are given any choice
as to the securities, cash or property to be received in a Fundamental Transaction, then the Holder shall be given the same choice
as to the Alternate Consideration it receives upon any exercise of this Warrant following such Fundamental Transaction.  The
Company shall cause any successor entity in a Fundamental Transaction in which the Company is not the survivor (the “Successor
Entity”) to assume in writing all of the obligations of the Company under this Warrant and the other Transaction Documents
in accordance with the provisions of this Section 3(e) pursuant to customary written agreements prior to such Fundamental
Transaction and shall, at the option of the Holder, deliver to the Holder in exchange for this Warrant a security of the Successor
Entity evidenced by a written instrument substantially similar in form and substance to this Warrant which is exercisable for a
corresponding number of shares of capital stock of such Successor Entity (or its parent entity) equivalent to the shares of Common
Stock acquirable and receivable upon exercise of this Warrant (without regard to any limitations on the exercise of this Warrant)
prior to such Fundamental Transaction, and with an exercise price which applies the exercise price hereunder to such shares of
capital stock (but taking into account the relative value of the shares of Common Stock pursuant to such Fundamental Transaction
and the value of such shares of capital stock, such number of shares of capital stock and such exercise price being for the purpose
of protecting the economic value of this Warrant immediately prior to the consummation of such Fundamental Transaction), and which
is reasonably satisfactory in form and substance to the Holder. Upon the occurrence of any such Fundamental Transaction, the Successor
Entity shall succeed to, and be substituted for, the Company (so that from and after the date of such Fundamental Transaction,
the provisions of this Warrant and the other Transaction Documents referring to the “Company” shall refer instead to
the Successor Entity), and the Successor Entity may exercise every right and power of the Company and shall assume all of the obligations
of the Company under this Warrant and the other Transaction Documents with the same effect as if such Successor Entity had been
named as the Company herein.

g)        Calculations.
All calculations under this Section 3 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may
be. For purposes of this Section 3, the number of shares of Common Stock deemed to be issued and outstanding as of a given
date shall be the sum of the number of shares of Common Stock (excluding treasury shares, if any) issued and outstanding.

 

h)        Notice to
Holder.

 

i.            Adjustment
to Exercise Price. Whenever the Exercise Price is adjusted pursuant to any provision of this Section 3, the Company shall
promptly mail to the Holder a notice setting forth the Exercise Price after such adjustment and any resulting adjustment to the
number of Warrant Shares and setting forth a brief statement of the facts requiring such adjustment.

 

ii.         Notice
to Allow Exercise by Holder. If, during the period in which this Warrant is outstanding, (A) the Company shall declare
a dividend (or any other distribution in whatever form) on the Common Stock, (B) the Company shall declare a special nonrecurring
cash dividend on or a redemption of the Common Stock, (C) the Company shall authorize the granting to all holders of the Common
Stock rights or warrants to subscribe for or purchase any shares of capital stock of any class or of any rights, (D) the approval
of any stockholders of the Company shall be required in connection with any reclassification of the Common Stock, any consolidation
or merger to which the Company is a party, any sale or transfer of all or substantially all of the assets of the Company, or any
compulsory share exchange whereby the Common Stock is converted into other securities, cash or property, or (E) the Company
shall authorize the voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Company, then, in each
case, the Company shall cause to be mailed to the Holder at its last address as it shall appear upon the Warrant Register of the
Company, at least 20 calendar days prior to the applicable record or effective date hereinafter specified, a notice stating (x) the
date on which a record is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record
is not to be taken, the date as of which the holders of the Common Stock of record to be entitled to such dividend, distributions,
redemption, rights or warrants are to be determined or (y) the date on which such reclassification, consolidation, merger,
sale, transfer or share exchange is expected to become effective or close, and the date as of which it is expected that holders
of the Common Stock of record shall be entitled to exchange their shares of the Common Stock for securities, cash or other property
deliverable upon such reclassification, consolidation, merger, sale, transfer or share exchange; provided that the failure to mail
such notice or any defect therein or in the mailing thereof shall not affect the validity of the corporate action required to be
specified in such notice.  To the extent that any notice provided hereunder constitutes, or contains, material, non-public
information regarding the Company or any of the Subsidiaries, the Company shall simultaneously file such notice with the Commission
pursuant to a Current Report on Form 8-K.  The Holder shall remain entitled to exercise this Warrant during the period
commencing on the date of such notice to the effective date of the event triggering such notice except as may otherwise be expressly
set forth herein.

pursuant to the Purchase Agreement and securities issued upon the exercise or conversion of those securities, and (iv) shares of
Common Stock issued or issuable by reason of a dividend, stock split or other distribution on shares of Common Stock (but only

provisions of this Warrant.

 

“Options”
means any rights, warrants or options to subscribe for or purchase shares of Common Stock or Convertible Securities.

 

“Option Value”
means the value of an Option based on the Black and Scholes Option Pricing model obtained from the “OV” function on

or its designated agent, together with a written assignment of this Warrant substantially in the form attached hereto duly executed

and shall issue to the assignor a new Warrant evidencing the portion of this Warrant not so assigned, and this Warrant shall promptly

this Warrant to the Company unless the Holder has assigned this Warrant in full, in which case, the Holder shall surrender this
Warrant to the Company within three (3) Trading Days of the date the Holder delivers an assignment form to the Company assigning
this Warrant full.  The Warrant, if properly assigned in accordance herewith, may be exercised by a new holder for the
purchase of Warrant Shares without having a new Warrant issued.

of this Warrant and shall be identical with this Warrant except as to the number of Warrant Shares issuable pursuant thereto.

 

c)        Warrant Register.
The Company shall register this Warrant, upon records to be maintained by the Company for that purpose (the “Warrant Register”),
in the name of the record Holder hereof from time to time.  The Company may deem and treat the registered Holder of this Warrant
as the absolute owner hereof for the purpose of any exercise hereof or any distribution to the Holder, and for all other purposes,
absent actual notice to the contrary.

 

d)        Transfer
Restrictions. If, at the time of the surrender of this Warrant in connection with any transfer of this Warrant, the transfer
of this Warrant shall not be either (i) registered pursuant to an effective registration statement under the Securities Act
and under applicable state securities or blue sky laws or (ii) eligible for resale without volume or manner-of-sale restrictions
or current public information requirements pursuant to Rule 144, the Company may require, as a condition of allowing such
transfer, that the Holder or transferee of this Warrant, as the case may be, comply with the provisions of Section 5.7 and
Section 4.16(a) of the Purchase Agreement.

 

e)        Representation
by the Holder. The Holder, by the acceptance hereof, represents and warrants that it is acquiring this Warrant and, upon any
exercise hereof, will acquire the Warrant Shares issuable upon such exercise, for its own account and not with a view to or for
distributing or reselling such Warrant Shares or any part thereof in violation of the Securities Act or any applicable state securities
law, except pursuant to sales registered or exempted under the Securities Act.

 

Section 5.          Miscellaneous.

 

a)        No Rights

a stockholder of the Company prior to the exercise hereof as set forth in Section 2(d)(i), except as expressly set forth in
Section 3.

 

b)        Loss, Theft,
Destruction or Mutilation of Warrant. The Company covenants that upon receipt by the Company of evidence reasonably satisfactory
to it of the loss, theft, destruction or mutilation of this Warrant or any stock certificate relating to the Warrant Shares, and
in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it (which, in the case of the Warrant,
shall not include the posting of any bond), and upon surrender and cancellation of such Warrant or stock certificate, if mutilated,
the Company will make and deliver a new Warrant or stock certificate of like tenor and dated as of such cancellation, in lieu of
such Warrant or stock certificate.

 

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

    	-14-

    	 

    

  

d)        Authorized
Shares.

 

The Company covenants
that, during the period the Warrant is outstanding, it will reserve from its authorized and unissued Common Stock a sufficient
number of shares to provide for the issuance of the Warrant Shares upon the exercise of any purchase rights under this Warrant. 
The Company further covenants that its issuance of this Warrant shall constitute full authority to its officers who are charged
with the duty of executing stock certificates to execute and issue the necessary Warrant Shares upon the exercise of the purchase
rights under this Warrant.  The Company will take all such reasonable action as may be necessary to assure that such Warrant
Shares may be issued as provided herein without violation of any applicable law or regulation, or of any requirements of the Trading
Market upon which the Common Stock may be listed.  The Company covenants that all Warrant Shares which may be issued upon
the exercise of the purchase rights represented by this Warrant will, upon exercise of the purchase rights represented by this
Warrant and payment for such Warrant Shares in accordance herewith, be duly authorized, validly issued, fully paid and nonassessable
and free from all taxes, liens and charges created by the Company in respect of the issue thereof (other than taxes in respect
of any transfer occurring contemporaneously with such issue).

 

Except and to the extent
as waived or consented to by the Holder, the Company shall not by any action, including, without limitation, amending its certificate
of incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities
or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will
at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary
or appropriate to protect the rights of Holder as set forth in this Warrant against impairment.  Without limiting the generality
of the foregoing, the Company will (i) not increase the par value of any Warrant Shares above the amount payable therefor upon
such exercise immediately prior to such increase in par value, (ii) take all such action as may be necessary or appropriate
in order that the Company may validly and legally issue fully paid and nonassessable Warrant Shares upon the exercise of this Warrant
and (iii) use commercially reasonable efforts to obtain all such authorizations, exemptions or consents from any public regulatory
body having jurisdiction thereof, as may be, necessary to enable the Company to perform its obligations under this Warrant.

 

Before taking any action
which would result in an adjustment in the number of Warrant Shares for which this Warrant is exercisable or in the Exercise Price,
the Company shall obtain all such authorizations or exemptions thereof, or consents thereto, as may be necessary from any public
regulatory body or bodies having jurisdiction thereof.

 

e)        Jurisdiction.
All questions concerning the construction, validity, enforcement and interpretation of this Warrant shall be determined in accordance
with the provisions of the Purchase Agreement.

 

    	-15-

    	 

    

  

f)         Restrictions.
The Holder acknowledges that the Warrant Shares acquired upon the exercise of this Warrant, if not registered, and the Holder does
not utilize cashless exercise, will have restrictions upon resale imposed by state and federal securities laws.

 

g)        No Net Cash
Settlement. The Holder acknowledges that, in the event that this Warrant is not exercisable for cash pursuant to Section 2
hereof, the Warrant Shares may not be settled with the Company for the cash value or in assets or otherwise.

 

h)        Nonwaiver
and Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the part of Holder shall operate
as a waiver of such right or otherwise prejudice the Holder’s rights, powers or remedies. Without limiting any other provision
of this Warrant or the Purchase Agreement, if the Company willfully and knowingly fails to comply with any provision of this Warrant,
which results in any material damages to the Holder, the Company shall pay to the Holder such amounts as shall be sufficient to
cover any costs and expenses including, but not limited to, reasonable attorneys’ fees, including those of appellate proceedings,
incurred by the Holder in collecting any amounts due pursuant hereto or in otherwise enforcing any of its rights, powers or remedies
hereunder.

 

i)         Notices.
Any notice, request or other document required or permitted to be given or delivered to the Holder by the Company shall be delivered
in accordance with the notice provisions of the Purchase Agreement.

 

j)         Limitation
of Liability. No provision hereof, in the absence of any affirmative action by the Holder to exercise this Warrant to purchase
Warrant Shares, and no enumeration herein of the rights or privileges of the Holder, shall give rise to any liability of the Holder
for the purchase price of any Common Stock or as a stockholder of the Company, whether such liability is asserted by the Company
or by creditors of the Company.

 

k)        Remedies.
The Holder, in addition to being entitled to exercise all rights granted by law, including recovery of damages, will be entitled
to specific performance of its rights under this Warrant.  The Company agrees that monetary damages would not be adequate
compensation for any loss incurred by reason of a breach by it of the provisions of this Warrant and hereby agrees to waive and
not to assert the defense in any action for specific performance that a remedy at law would be adequate.

 

l)         Successors
and Assigns. Subject to applicable securities laws, this Warrant and the rights and obligations evidenced hereby shall inure
to the benefit of and be binding upon the successors and permitted assigns of the Company and the successors and permitted assigns
of Holder.  The provisions of this Warrant are intended to be for the benefit of any Holder from time to time of this Warrant
and shall be enforceable by the Holder or holder of Warrant Shares.

 

m)        Amendment.
This Warrant may be modified or amended or the provisions hereof waived with the written consent of the Company and the Holder.

 

n)        Severability.
Wherever possible, each provision of this Warrant shall be interpreted in such manner as to be effective and valid under applicable
law, but if any provision of this Warrant shall be prohibited by or invalid under applicable law, such provision shall be ineffective
to the extent of such prohibition or invalidity, without invalidating the remainder of such provisions or the remaining provisions
of this Warrant.

 

    	-16-

    	 

    

  

o)        Headings.
The headings used in this Warrant are for the convenience of reference only and shall not, for any purpose, be deemed a part of
this Warrant.

Company and each Subsidiary (as defined below) has been duly organized and is validly existing as a corporation in good standing
(or the foreign equivalent thereof) under the laws of each of their respective jurisdictions of organization. The Company and each
Subsidiary is duly qualified to do business and is in good standing as a foreign corporation in each jurisdiction in which its
ownership or lease of property or the conduct of its business requires such qualification and has all power and authority necessary

the condition (financial or otherwise), results of operations, assets, properties or business or prospects of the Company
or any Subsidiary, taken as a whole, or (ii) impair in any material respect the ability of the Company to perform its obligations
under this Agreement or to consummate any transactions contemplated by the Agreement (any such effect as described in clauses (i)
or (ii), a “Material Adverse Effect”). The Company owns or controls, directly or indirectly, only the following corporations,
partnerships, limited liability partnerships, limited liability companies, associations or other entities: Star Tobacco, Inc.,

Company has the requisite right, power and authority to enter into this Agreement and the Warrants, to authorize, issue and sell
the Securities as contemplated by this Agreement to perform and to discharge its obligations hereunder and thereunder, to issue
the Warrant Shares upon the due exercise of the Warrants; and each of this Agreement and the Warrants have been duly authorized,

provisions contained therein may further be limited by applicable laws and principles of public policy.

 

(c)          The
Shares and Warrants to be issued and sold by the Company to the Purchasers hereunder have been duly authorized and the Shares,
when issued and delivered against payment therefor as provided herein and the Warrant Shares, when issued and delivered against
payment therefor as provided in the Warrants, will be validly issued, fully paid and non-assessable and free of any preemptive

Act, which became effective on February 6, 2015 (the “Effective Date”), including the Prospectus, and such amendments
and supplements thereto as may have been required to the date of this Agreement in connection with the sale of the Shares hereunder.
The Registration Statement is effective under the Securities Act and no stop order preventing or suspending the effectiveness of
the Registration Statement or suspending or preventing the use of the Prospectus has been issued by the Commission and no proceedings
for that purpose have been instituted or, to the knowledge of the Company, are threatened by the Commission. The Company, if required
by the rules and regulations of the Commission, proposes to file the Prospectus, with the Commission pursuant to Rule 424(b) in
relation to the sale of the Shares. At the time the Registration Statement and any amendments thereto became effective, at the

fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading;
and the Prospectus and any amendments or supplements thereto, at time the Prospectus or any amendment or supplement thereto was
issued and at the Closing Date, conformed and will conform in all material respects to the requirements of the Securities Act and
did not and will not contain an untrue statement of a material fact or omit to state a material fact necessary in order to make
the statements therein, in light of the circumstances under which they were made, not misleading. and will conform to the description
thereof contained in the Registration Statement and the Prospectus. The Company has reserved from its duly authorized capital stock

of capital stock of the Company have been duly authorized and validly issued, are fully paid and non-assessable, have been
issued in all material respects in compliance with United States federal and state securities laws, and conform to the description

Common Stock or restricted stock units pursuant to employee stock option or purchase plans, or the issuance of Common Stock of
the Company issued pursuant to an At Market Issuance Sales Agreement between the Company and MLV & Co. LLC, dated December

or purchase securities of the Company. There are no authorized or outstanding shares of capital stock, options, warrants, preemptive
rights, rights of first refusal or other rights to purchase, or equity or debt securities convertible into or exchangeable
or exercisable for, any capital stock of the Company or any Subsidiary other than those described above, those described on

the outstanding shares of capital stock of each Subsidiary have been duly authorized and validly issued, are fully paid and non-assessable

to, any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to which the Company or any Subsidiary
is a party or by which the Company or any Subsidiary is bound or to which any of the property or assets of the Company or
any Subsidiary is subject (each, a “Contract” and, collectively, the “Contracts”); (ii) result

singularly or in the aggregate, would not have a Material Adverse Effect. A “Debt Repayment Triggering Event”

or other evidence of indebtedness (or any person acting on such holder’s behalf) the right to require the repurchase, redemption

business combination, poison pill (including any distribution under a rights agreement) or other similar anti-takeover provision
under the Company’s certificate of incorporation (or similar charter documents) or the laws of its state of incorporation
that is or could become applicable to the Purchasers as a result of the Purchasers and the Company fulfilling their obligations
or exercising their rights under the Securities, including without limitation as a result of the Company’s issuance of the
Securities and the Purchasers’ ownership of the Securities.

is the subject which (i) is required to be described in the Registration Statement or the Prospectus or a document incorporated
by reference therein and is not described therein, or (ii) singularly or in the aggregate, if determined adversely to the

foreign regulatory agencies or bodies which are necessary for the ownership of its properties or the conduct of their respective
businesses as described in the Registration Statement and the Prospectus (collectively, the “Governmental Permits”),

full force and effect would not, singularly or in the aggregate, reasonably be expected to have a Material Adverse Effect. To the
Company’s knowledge, all such Governmental Permits are free and clear of any material restriction or condition that are in
addition to, or materially different from those normally applicable to similar licenses, certificates, authorizations and permits.

or “accumulated funding deficiency” (as defined in Section 302 of ERISA) or any of the events set forth
in Section 4043(b) of ERISA (other than events with respect to which the thirty (30)-day notice requirement under Section 4043
of ERISA has been waived) has occurred or would reasonably be expected to occur with respect to any employee benefit plan
of the Company or any Subsidiary which would, singularly or in the aggregate, reasonably be expected to have a Material
Adverse Effect. Each employee benefit plan of the Company or any Subsidiary is in compliance in all material respects with
applicable law, including ERISA and the Code.  The Company and each Subsidiary has not incurred and would not reasonably
be expected to incur liability under Title IV of ERISA with respect to the termination of, or withdrawal from, any pension plan
(as defined in ERISA). Each pension plan for which the Company or any Subsidiary would have any liability that is intended
to be qualified under Section 401(a) of the Code is so qualified, and nothing has occurred, whether by action or by failure
to act, which would, singularly or in the aggregate, cause the loss of such qualification to the extent such loss would reasonably
be expected to have a Material Adverse Effect.

(u)          To
the Company’s knowledge, the Company and each Subsidiary is in compliance with all foreign, federal, state and local rules, laws
and regulations relating to the use, treatment, storage and disposal of hazardous or toxic substances or waste and protection
of health and safety or the environment which are applicable to its businesses (“Environmental Laws”),
except where the failure to comply would not, singularly or in the aggregate, reasonably be expected to have a Material Adverse
Effect. There has been no storage, generation, transportation, handling, treatment, disposal, discharge, emission, or other release
of any kind of toxic or other wastes or other hazardous substances regulated by Environmental Laws (“Hazardous
Substances”) by or caused by the Company or any Subsidiary (or, to the Company’s knowledge and without
independent investigation, any other entity for whose acts or omissions the Company or any Subsidiary is or may otherwise
be liable) upon any of the property now or previously owned or leased by the Company or any Subsidiary, or upon any other
property, in violation of any law, statute, ordinance, rule, regulation, order, judgment, decree or permit or which would, under
any law, statute, ordinance, rule (including rule of common law), regulation, order, judgment, decree or permit, give rise to any
liability, except for any violation or liability which would not reasonably be expected to have, singularly or in the aggregate
with all such violations and liabilities, a Material Adverse Effect; to the Company’s knowledge and without independent investigation,
there has been no disposal, discharge, emission or other release onto property now leased by the Company or any Subsidiary or into
the environment surrounding such property of any Hazardous Substance, except for any such disposal, discharge, emission, or
other release in violation of Environmental Laws which would not reasonably be expected to have, singularly or in the aggregate
with all such discharges and other releases, a Material Adverse Effect.

 

(v)         The
Company and each Subsidiary (i) has timely filed (or filed an extension to file) all necessary federal, state, local and foreign
tax returns, and all such filed returns were true, complete and correct, (ii) has paid all federal, state, local and foreign
taxes, assessments, governmental or other charges due and payable for which it is liable, including, without limitation, all
sales and use taxes and all taxes which the Company or any Subsidiary is obligated to withhold from amounts owing to employees,
creditors and third parties, and (iii) does not have any tax deficiency or claims outstanding or assessed or, to its knowledge,
proposed against any of them, except those, in each of the cases described in clauses (i), (ii) and (iii) of this paragraph
(bb), that would not, singularly or in the aggregate, reasonably be expected to have a Material Adverse Effect. The Company
and each Subsidiary has not engaged in any transaction which, to the Company’s knowledge, is a corporate tax shelter
or which could reasonably be characterized as such by the Internal Revenue Service or any other taxing authority. The accruals
and reserves on the books and records of the Company in respect of tax liabilities for any taxable period not yet finally
determined are adequate to meet any assessments and related liabilities for any such period, and since December 31, 2014, the Company
and each Subsidiary has not incurred any liability for taxes other than in the ordinary course.

 

    	-14-

    	 

    

 

(w)          The
Company and each Subsidiary carries, or is covered by, insurance provided by institutions of recognized financial responsibility
with policies in such amounts and covering such risks as is adequate for the conduct of their respective businesses and the
value of its properties and as is customary for companies engaged in similar businesses in similar industries. The Company has
no reason to believe that it or any Subsidiary will not be able (i) to renew its existing insurance coverage as and when such policies
expire or (ii) to obtain comparable coverage from similar institutions as may be necessary or appropriate to conduct their
respective businesses as now conducted and at a cost that would not reasonably be expected to result in a Material Adverse Effect.
Neither the Company nor any Subsidiary has been denied any insurance coverage that it has sought or for which it has applied.

 

(x)          The
Company and each Subsidiary maintains a system of internal accounting and other controls sufficient to provide reasonable assurances
that (i) transactions are executed in accordance with management’s general or specific authorizations; (ii) transactions
are recorded as necessary to permit preparation of financial statements in conformity with GAAP and to maintain accountability
for assets; (iii) access to assets is permitted only in accordance with management’s general or specific authorization; and
(iv) the recorded accountability for assets is compared with existing assets at reasonable intervals and appropriate action
is taken with respect to any differences. Except as described in the Registration Statement and the Prospectus, since the end of
the Company’s most recent audited fiscal year, there as been (A) no material weakness in the Company’s internal control
over financial reporting (whether or not remediated) and (B) no change in the Company’s internal control over financial reporting
that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial
reporting.

 

(y)          There
is no franchise, lease, contract, agreement or document required by the Securities Act or by the Rules and Regulations to be described
in the Registration Statement and the Prospectus or a document incorporated by reference therein or to be filed as an exhibit to
the Registration Statement or a document incorporated by reference therein which is not described or filed therein as required;
and all descriptions of any such franchises, leases, contracts, agreements or documents contained in the Registration Statement
and the Prospectus or in a document incorporated by reference therein are accurate and complete descriptions of such documents
in all material respects. Other than as described in the Registration Statement and the Prospectus, no such franchise, lease, contract
or agreement has been suspended or terminated for convenience or default by the Company or any Subsidiary or any of the
other parties thereto, and neither the Company nor any Subsidiary has received notice nor does the Company have any other
knowledge of any such pending or threatened suspension or termination, except for such pending or threatened suspensions
or terminations that would not reasonably be expected to, singularly or in the aggregate, have a Material Adverse Effect.

(z)          No
relationship, direct or indirect, exists between or among the Company and any Subsidiary on the one hand, and the directors, officers,
shareholders (or analogous interest holders), customers or suppliers of the Company or any Subsidiary or any of their affiliates
on the other hand, which is required to be described in the Registration Statement and the Prospectus or a document incorporated
by reference therein and which is not so described.

 

(aa)         Except
as described in the Registration Statement and the Prospectus, there are no persons with registration rights or similar rights
to have any securities registered by the Company or any Subsidiary under the Securities Act. No person or entity has the right
to require registration of shares of Common Stock or other securities of the Company or any Subsidiary because of the filing or
effectiveness of the Registration Statement, except for persons and entities who have expressly waived such right in writing or
who have been given timely and proper written notice and have failed to exercise such right within the time or times
required under the terms and conditions of such right.

 

(bb)         Neither
the Company nor any Subsidiary owns any “margin securities” as that term is defined in Regulation U of the Board of
Governors of the Federal Reserve System (the “Federal Reserve Board”), and none of
the proceeds of the sale of the Securities will be used, directly or indirectly, for the purpose of purchasing or carrying any
margin security, for the purpose of reducing or retiring any indebtedness which was originally incurred to purchase or carry
any margin security or for any other purpose which might cause any of the Securities to be considered a “purpose credit”
within the meanings of Regulation T, U or X of the Federal Reserve Board.

 

(cc)         Except
for this Agreement, neither the Company nor any Subsidiary is a party to any contract, agreement or understanding with any person
that would give rise to a valid claim against the Company or the Placement Agent for a brokerage commission, finder’s
fee or like payment in connection with the offering and sale of the Securities or any transaction contemplated by this Agreement
or the Registration Statement or the Prospectus.

 

(dd)         No
forward-looking statement (within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act)
contained in either the Registration Statement or the Prospectus has been made or reaffirmed without a reasonable basis or has
been disclosed other than in good faith.

 

(ee)         The
Company is subject to and in compliance in all material respects with the reporting requirements of Section 13 or Section 15(d)
of the Exchange Act. The Common Stock is registered pursuant to Section 12(b) of the Exchange Act and is listed on the
NASDAQ Capital Market, and the Company has taken no action designed to, or reasonably likely to have the effect of, terminating
the registration of the Common Stock under the Exchange Act or delisting the Common Stock from the NASDAQ Capital Market,
nor has the Company received any notification that the Commission, the NASDAQ Capital Market or FINRA is contemplating terminating
such registration or listing, in each case except as described in the Registration Statement and the Prospectus. The Company has
obtained or will have obtained, or has made or will have made, as applicable, all necessary consents, approvals, authorizations
or orders of, or filing, notification or registration with, the NASDAQ Capital Market required for the listing and trading
of the Shares and the Warrant Shares on the NASDAQ Capital Market.

(as such term is defined in Rule 405 of the Securities Act) and any unconsolidated entity, including, but not limited to, any structured
finance, special purpose or limited purpose entity that would reasonably be expected to materially affect the Company’s or
any Subsidiary’s liquidity or the availability of or requirements for their capital resources required to be described in
the Registration Statement and the Prospectus or a document incorporated by reference therein which have not been described as
required.

 

(jj)         There
are no outstanding loans, advances (except normal advances for business expenses in the ordinary course of business) or guarantees
or indebtedness by the Company to or for the benefit of any of the officers or directors of the Company or any of their respective
family members, except as disclosed in the Registration Statement and the Prospectus.

(mm)      Neither
the Company nor any Subsidiary nor, to the knowledge of the Company, any director, officer, agent, employee or affiliate of the
Company or any Subsidiary is currently subject to any U.S. sanctions administered by the Office of Foreign Assets Control
of the U.S. Treasury Department (“OFAC”); and the Company will not directly or indirectly use the proceeds of

to each product subject to the jurisdiction of the U.S. Food and Drug Administration (“FDA”) under the Federal
Food, Drug and Cosmetic Act, as amended, and the regulations thereunder (“FDCA”) that is manufactured, packaged,
labeled, tested, distributed, sold, and/or marketed by the Company or any of its Subsidiaries (each such product, a “Pharmaceutical
Product”), such Pharmaceutical Product is being manufactured, packaged, labeled, tested, distributed, sold and/or marketed

investigational use, premarket clearance, licensure, or application approval, good manufacturing practices, good laboratory practices,
good clinical practices, product listing, quotas, labeling, advertising, record keeping and filing of reports, except where the

or, to the Company's knowledge, threatened, action (including any lawsuit, arbitration, or legal or administrative or regulatory
proceeding, charge, complaint, or investigation) against the Company or any of its Subsidiaries, and none of the Company or any

(qq)       Except
with respect to the material terms and conditions of the transactions contemplated by the Transaction Documents, the Company confirms
that neither it nor any other Person acting on its behalf has provided any of the Purchasers or their agents or counsel with any
information that it believes constitutes or might constitute material, non-public information which is not otherwise disclosed
in the Prospectus Supplement. The Company understands and confirms that the Purchasers will rely on the foregoing representation
in effecting transactions in securities of the Company. All of the disclosure furnished by or on behalf of the Company to the Purchasers
regarding the Company and its Subsidiaries, their respective businesses and the transactions contemplated hereby, including in
any schedule to this Agreement, is true and correct and does not contain any untrue statement of a material fact or omit to state
any material fact necessary in order to make the statements made therein, in light of the circumstances under which they were made,
not misleading. The press releases disseminated by the Company during the twelve months preceding the date of this Agreement taken
as a whole do not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein
or necessary in order to make the statements therein, in light of the circumstances under which they were made and when made, not
misleading. The Company acknowledges and agrees that no Purchaser makes or has made any representations or warranties with respect
to the transactions contemplated hereby other than those specifically set forth in Section 3.2 hereof.

 

3.2          Representations
and Warranties of the Purchasers. Each Purchaser, for itself and for no other Purchaser, hereby represents and warrants as
of the date hereof and as of the Closing Date to the Company as follows (unless as of a specific date therein):

 

(a)          Organization;
Authority. Such Purchaser is either an individual or an entity duly incorporated or formed, validly existing and in good standing
under the laws of the jurisdiction of its incorporation or formation with full right, corporate, partnership, limited liability
company or similar power and authority to enter into and to consummate the transactions contemplated by this Agreement and otherwise
to carry out its obligations hereunder and thereunder. The execution and delivery of this Agreement and performance by such Purchaser
of the transactions contemplated by this Agreement have been duly authorized by all necessary corporate, partnership, limited liability
company or similar action, as applicable, on the part of such Purchaser. Each Transaction Document to which it is a party has been
duly executed by such Purchaser, and when delivered by such Purchaser in accordance with the terms hereof, will constitute the
valid and legally binding obligation of such Purchaser, enforceable against it in accordance with its terms, except: (i) as limited
by general equitable principles and applicable bankruptcy, insolvency, reorganization, moratorium and other laws of general application
affecting enforcement of creditors’ rights generally, (ii) as limited by laws relating to the availability of specific performance,
injunctive relief or other equitable remedies and (iii) insofar as indemnification and contribution provisions may be limited by
applicable law. The Purchaser’s execution, delivery and performance of this Agreement and the other Transaction Documents
and the consummation by it of the transactions contemplated hereby do not and will not (i) conflict with or violate any provision
of the Purchaser’s certificate or articles of incorporation, bylaws or other organizational or charter documents, or (ii)
conflict with or result in a violation of any law, rule, regulation, order, judgment, injunction, decree or other restriction of
any court or governmental authority to which the Purchaser is subject (including federal and state securities laws and regulations),
or by which any property or asset of the Purchaser is bound or affected.

 

    	-19-

    	 

    

 

(b)          Understandings
or Arrangements. Such Purchaser is acquiring the Securities as principal for its own account and has no direct or indirect
arrangement or understandings with any other persons to distribute or regarding the distribution of such Securities (this representation
and warranty not limiting such Purchaser’s right to sell the Securities pursuant to the Registration Statement or otherwise
in compliance with applicable federal and state securities laws). Such Purchaser is acquiring the Securities hereunder in the ordinary
course of its business.

 

(c)          Access
to Information. Such Purchaser acknowledges that it has had the opportunity to review the Transaction Documents (including
all exhibits and schedules thereto) and the Company’s filings with the Commission and has been afforded (i) the opportunity
to ask such questions as it has deemed necessary of, and to receive answers from, representatives of the Company concerning the
terms and conditions of the offering of the Shares and the merits and risks of investing in the Shares; (ii) access to information
about the Company and its financial condition, results of operations, business, properties, management and prospects sufficient
to enable it to evaluate its investment; and (iii) the opportunity to obtain such additional information that the Company possesses
or can acquire without unreasonable effort or expense that is necessary to make an informed investment decision with respect to
the investment. Such Purchaser acknowledges and agrees that neither the Placement Agent nor any Affiliate of the Placement Agent
has provided such Purchaser with any information or advice with respect to the Securities nor is such information or advice necessary
or desired. Neither the Placement Agent nor any Affiliate has made or makes any representation as to the Company or the quality
of the Securities and the Placement Agent and any Affiliate may have acquired non-public information with respect to the Company
which such Purchaser agrees need not be provided to it. In connection with the issuance of the Securities to such Purchaser, neither
the Placement Agent nor any of its Affiliates has acted as a financial advisor or fiduciary to such Purchaser.

 

(d)          Certain
Transactions and Confidentiality. Other than consummating the transactions contemplated hereunder, such Purchaser has not,
nor has any Person acting on behalf of or pursuant to any understanding with such Purchaser, directly or indirectly executed any
purchases or sales, including Short Sales, of the securities of the Company during the period commencing as of the time that such
Purchaser first received a term sheet (written or oral) from the Company or any other Person representing the Company setting forth
the material pricing terms of the transactions contemplated hereunder and ending immediately prior to the execution hereof. Notwithstanding
the foregoing, in the case of a Purchaser that is a multi-managed investment vehicle whereby separate portfolio managers manage
separate portions of such Purchaser’s assets and the portfolio managers have no direct knowledge of the investment decisions
made by the portfolio managers managing other portions of such Purchaser’s assets, the representation set forth above shall
only apply with respect to the portion of assets managed by the portfolio manager that made the investment decision to purchase
the Securities covered by this Agreement. Other than to other Persons party to this Agreement, such Purchaser has maintained the
confidentiality of all disclosures made to it in connection with this transaction (including the existence and terms of this transaction).
Notwithstanding the foregoing, for avoidance of doubt, nothing contained herein shall constitute a representation or warranty,
or preclude any actions, with respect to the identification of the availability of, or securing of, available shares to borrow
in order to effect Short Sales or similar transactions in the future.

 

    	-20-

    	 

    

 

(e)          Ownership.
The Purchaser’s signature page sets forth all securities of the Company held or beneficially owned by such Purchaser as of
the date hereof, including without limitation, Common Stock and Common Stock Equivalents. Such Purchaser does not hold or beneficially
own any other securities of the Company, except as indicated on the signature page hereto.

 

(f)          Group.
Such Purchaser represents that it is not a “group” within the meaning of Section 13d-5 under the Exchange Act with
any holder or beneficial owner of the Company’s securities and in calculating and reporting such Purchaser’s beneficial
ownership, such Purchaser is not required under the rules and regulations promulgated under the Exchange Act to include the beneficial
ownership of the securities of the Company held by another holder or beneficial owner of the Company’s securities.

 

The Company acknowledges and agrees that
the representations contained in Section 3.2 shall not modify, amend or affect such Purchaser’s right to rely on the Company’s
representations and warranties contained in this Agreement or any representations and warranties contained in any other Transaction
Document or any other document or instrument executed and/or delivered in connection with this Agreement or the consummation of
the transaction contemplated hereby.

 

ARTICLE
IV.

OTHER
AGREEMENTS OF THE PARTIES

 

4.1          Warrant
Shares. If all or any portion of a Warrant is exercised at a time when there is an effective registration statement to cover
the issuance or resale of the Warrant Shares or if the Warrant is exercised via cashless exercise, the Warrant Shares issued pursuant
to any such exercise shall be issued free of all legends. If at any time following its effective date, a registration statement
registering the sale or resale of the Warrant Shares is not effective or is not otherwise available for the sale or resale of the
Warrant Shares, the Company shall immediately notify the holders of the Warrants in writing that such registration statement is
not then effective and thereafter shall promptly notify such holders when the registration statement is effective again and available
for the sale or resale of the Warrant Shares (it being understood and agreed that the foregoing shall not limit the ability of
the Company to issue, or any Purchaser to sell, any of the Warrant Shares in compliance with applicable federal and state securities
laws). The Company shall use reasonable best efforts to keep a registration statement registering the issuance or resale of the
Warrant Shares effective during the period commencing on the effective date thereof and terminating on the expiration of the Warrants.
Upon a cashless exercise of a Warrant, the holding period for purposes of Rule 144 shall tack back to the original date of issuance
of the Warrant. For purposes of clarity, the Shares shall be issued free of legends.

4.2          Furnishing
of Information; Public Information.

 

(a)          Until
the earliest of the time that (i) no Purchaser owns Securities or (ii) the Warrants have expired, the Company covenants to timely
file (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by
the Company after the date hereof pursuant to the Exchange Act even if the Company is not then subject to the reporting requirements
of the Exchange Act. As long as any Purchaser owns Securities, if the Company is not required to file reports pursuant to the Exchange
Act, it will prepare and furnish to the Purchasers and make publicly available in accordance with Rule 144(c) such information
as is required for the Purchasers to sell the Securities, including without limitation, under Rule 144. The Company further covenants
that it will take such further action as any holder of Securities may reasonably request, to the extent required from time to time
to enable such Person to sell such Securities without registration under the Securities Act, including without limitation, within
the requirements of the exemption provided by Rule 144.

 

(b)          At
any time during the period commencing from the six (6) month anniversary of the date hereof and ending at such time that all of
the Securities may be sold without the requirement for the Company to be in compliance with Rule 144(c)(1) and otherwise without
restriction or limitation pursuant to Rule 144, if the Company shall fail for any reason to satisfy the current public information
requirement under Rule 144(c) (a “Public Information Failure”) then, in addition to such Purchaser’s other
available remedies, the Company shall pay to a Purchaser, in cash, as partial liquidated damages and not as a penalty, by reason
of any such delay in or reduction of its ability to sell the Securities, an amount in cash equal to two percent (2.0%) of the aggregate
market value of the Securities held by the Purchaser on the day of a Public Information Failure (as measured by the VWAP of the
Common Stock on the applicable date or dates) and on every thirtieth (30th) day (pro rated for periods totaling less than thirty
days) thereafter until the earlier of (a) the date such Public Information Failure is cured and (b) such time that such public
information is no longer required for the Purchasers to transfer the Warrant Shares pursuant to Rule 144. The payments to which
a Purchaser shall be entitled pursuant to this Section 4.3(b) are referred to herein as “Public Information Failure Payments.”
Public Information Failure Payments shall be paid on the earlier of (i) the last day of the calendar month during which such
Public Information Failure Payments are incurred and (ii) the third (3rd) Business Day after the event or failure giving
rise to the Public Information Failure Payments is cured. In the event the Company fails to make Public Information Failure Payments
in a timely manner, such Public Information Failure Payments shall bear interest at the rate of 1.5% per month (prorated for partial
months) until paid in full. Nothing herein shall limit such Purchaser’s right to pursue actual damages for the Public Information
Failure, and such Purchaser shall have the right to pursue all remedies available to it at law or in equity including, without
limitation, a decree of specific performance and/or injunctive relief. Notwithstanding the foregoing, the Public Information Failure
Payments shall not apply during such time as the Warrant Shares are registered on an effective Registration Statement.

4.3          Integration.
The Company shall not sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined
in Section 2 of the Securities Act) that would be integrated with the offer or sale of the Securities for purposes of the rules
and regulations of any Trading Market such that it would require shareholder approval prior to the closing of such other transaction
unless shareholder approval is obtained before the closing of such subsequent transaction.

 

4.4          Securities
Laws Disclosure; Publicity. The Company shall (a) by 9:00 a.m. (New York City time) on the Trading Day immediately following
the date hereof, issue a press release disclosing the material terms of the transactions contemplated hereby, and (b) file a Current
Report on Form 8-K, including the Transaction Documents as exhibits thereto, with the Commission within the time required by the
Exchange Act. From and after the issuance of such press release, the Company represents to the Purchasers that it shall have publicly
disclosed all material, non-public information delivered to any of the Purchasers by the Company or any of its Subsidiaries, or
any of their respective officers, directors, employees or agents in connection with the transactions contemplated by the Transaction
Documents. The Company and each Purchaser shall consult with each other in issuing any other press releases with respect to the
transactions contemplated hereby, and neither the Company nor any Purchaser shall issue any such press release nor otherwise make
any such public statement with respect to the transactions contemplated hereby without the prior consent of the Company, with respect
to any press release of any Purchaser, or without the prior consent of each Purchaser, with respect to any press release of the
Company (other than the press release described in the first sentence of this Section 4.4), which consent shall not unreasonably
be withheld or delayed, except if such disclosure is required by law, in which case the disclosing party shall promptly provide
the other party with prior notice of such public statement or communication. Notwithstanding the foregoing, the Company shall not
publicly disclose the name of any Purchaser, or include the name of any Purchaser in any filing with the Commission or any regulatory
agency or Trading Market, without the prior written consent of such Purchaser, except (a) as required by federal securities law
in connection with the filing of final Transaction Documents with the Commission and (b) to the extent such disclosure is required
by law or Trading Market regulations, in which case the Company shall provide the Purchasers with prior notice of such disclosure
permitted under this clause (b).

 

4.5          Shareholder
Rights Plan. No claim will be made or enforced by the Company or, with the consent of the Company, any other Person, that any
Purchaser is an “Acquiring Person” under any control share acquisition, business combination, poison pill (including
any distribution under a rights agreement) or similar anti-takeover plan or arrangement in effect or hereafter adopted by the Company,
or that any Purchaser could be deemed to trigger the provisions of any such plan or arrangement, by virtue of receiving Securities
under the Transaction Documents or under any other agreement between the Company and the Purchasers.

4.6          Non-Public
Information. Except with respect to the material terms and conditions of the transactions contemplated by the Transaction Documents,
the Company covenants and agrees that neither it, nor any other Person acting on its behalf will provide any Purchaser or its agents
or counsel with any information that the Company believes constitutes material non-public information, unless prior thereto such
Purchaser shall have entered into a written agreement with the Company regarding the confidentiality and use of such information.
The Company understands and confirms that each Purchaser shall be relying on the foregoing covenant in effecting transactions in
securities of the Company.

 

4.7          Use
of Proceeds. The Company shall use the net proceeds from the sale of the Securities hereunder as described in the Prospectus
Supplement and shall not use such proceeds: (a) for the satisfaction of any portion of the Company’s debt (other than payment
of trade payables in the ordinary course of the Company’s business and prior practices), (b) for the redemption of any Common
Stock or Common Stock Equivalents, other than with respect to repurchases or similar transactions of Common Stock or Common Stock
Equivalents in connection with the termination of service of any holder of such Common Stock or Common Stock Equivalents as provided
in any of the Company’s equity-based compensation plans (c) for the settlement of any outstanding litigation or (d) in violation
of FCPA or OFAC regulations.

 

4.8           Indemnification
of Purchasers. Subject to the provisions of this Section 4.8, the Company will indemnify and hold each Purchaser and its directors,
officers, shareholders, members, partners, employees and agents (and any other Persons with a functionally equivalent role of a
Person holding such titles notwithstanding a lack of such title or any other title), each Person who controls such Purchaser (within
the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, shareholders,
agents, members, partners or employees (and any other Persons with a functionally equivalent role of a Person holding such titles
notwithstanding a lack of such title or any other title) of such controlling persons (each, a “Purchaser Party”)
harmless from any and all losses, liabilities, obligations, claims, contingencies, damages, costs and expenses, including all judgments,
amounts paid in settlements, court costs and reasonable attorneys’ fees and costs of investigation that any such Purchaser
Party may suffer or incur as a result of or relating to (a) any breach of any of the representations, warranties, covenants or
agreements made by the Company in this Agreement or in the other Transaction Documents or (b) any action instituted against the
Purchaser Parties in any capacity, or any of them or their respective Affiliates, by any stockholder of the Company who is not
an Affiliate of such Purchaser Party, with respect to any of the transactions contemplated by the Transaction Documents (unless
such action is based upon a breach of such Purchaser Party’s representations, warranties or covenants under the Transaction
Documents or any agreements or understandings such Purchaser Party may have with any such stockholder or any violations by such
Purchaser Party of state or federal securities laws or any conduct by such Purchaser Party which constitutes fraud, gross negligence,
willful misconduct or malfeasance). If any action shall be brought against any Purchaser Party in respect of which indemnity may
be sought pursuant to this Agreement, such Purchaser Party shall promptly notify the Company in writing, and the Company shall
have the right to assume the defense thereof with counsel of its own choosing reasonably acceptable to the Purchaser Party. Any
Purchaser Party shall have the right to employ separate counsel in any such action and participate in the defense thereof, but
the fees and expenses of such counsel shall be at the expense of such Purchaser Party except to the extent that (i) the employment
thereof has been specifically authorized by the Company in writing, (ii) the Company has failed after a reasonable period of time
to assume such defense and to employ counsel or (iii) in such action there is, in the reasonable opinion of counsel, a material
conflict on any material issue between the position of the Company and the position of such Purchaser Party, in which case the
Company shall be responsible for the reasonable fees and expenses of no more than one such separate counsel. The Company will not
be liable to any Purchaser Party under this Agreement (y) for any settlement by a Purchaser Party effected without the Company’s
prior written consent, which shall not be unreasonably withheld or delayed; or (z) to the extent, but only to the extent that a
loss, claim, damage or liability is attributable to any Purchaser Party’s breach of any of the representations, warranties,
covenants or agreements made by such Purchaser Party in this Agreement or in the other Transaction Documents. The indemnification
required by this Section 4.8 shall be made by periodic payments of the amount thereof during the course of the investigation or
defense, as and when bills are received or are incurred. The indemnity agreements contained herein shall be in addition to any
cause of action or similar right of any Purchaser Party against the Company or others and any liabilities the Company may be subject
to pursuant to law.

4.9          Reservation
of Common Stock. As of the date hereof, the Company has reserved and the Company shall continue to reserve and keep available
at all times, free of preemptive rights, a sufficient number of shares of Common Stock for the purpose of enabling the Company
to issue Shares pursuant to this Agreement and Warrant Shares pursuant to any exercise of the Warrants.

 

4.10        Listing
of Common Stock. The Company hereby agrees to use best efforts to maintain the listing or quotation of the Common Stock on
the Trading Market on which it is currently listed, and concurrently with the Closing, the Company shall apply to list or quote
all of the Shares and Warrant Shares on such Trading Market and promptly secure the listing of all of the Shares and Warrant Shares
on such Trading Market. The Company further agrees, if the Company applies to have the Common Stock traded on any other Trading
Market, it will then include in such application all of the Shares and Warrant Shares, and will take such other action as is necessary
to cause all of the Shares and Warrant Shares to be listed or quoted on such other Trading Market as promptly as possible. The
Company will then take all action reasonably necessary to continue the listing and trading of its Common Stock on a Trading Market
and will comply in all respects with the Company’s reporting, filing and other obligations under the bylaws or rules of the
Trading Market. The Company agrees to maintain the eligibility of the Common Stock for electronic transfer through the Depository
Trust Company or another established clearing corporation, including, without limitation, by timely payment of fees to the Depository
Trust Company or such other established clearing corporation in connection with such electronic transfer.

 

4.11        Subsequent
Equity Sales.

 

(a)          From
the date hereof until ninety (90) days after the Closing Date (the “Lock-Up Period”), neither the Company nor
any Subsidiary shall directly or indirectly offer, sell, assign, transfer, pledge, contract to sell, or otherwise dispose of, any
shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock, other than: (i) the
Company's sale of the Securities hereunder; (ii) the issuance of restricted Common Stock, restricted stock units or options to
acquire Common Stock pursuant to the Company's employee benefit plans, qualified stock option plans or other employee compensation
plans as such plans are in existence on the date hereof and described in the Registration Statement or the Prospectus Supplement;
(iii) the issuance of Common Stock pursuant to the valid exercises of options, warrants or rights or vesting of restricted stock
units outstanding on the date hereof; and (iv) the issuance of Common Stock or securities convertible into or exercisable or exchange
for shares of Common Stock pursuant to any agreement existing on the date hereof or any strategic partnership, joint venture, acquisition,
merger collaboration, lending or other contractual arrangement or in connection with the acquisition or license by the Company
of any business, products or technologies or pursuant to a private placement solely to strategic investor (not including a financial
investor) in which the purchaser agrees to be subject to restrictions on the transfer of such purchased securities substantially
similar to those described hereunder. The Company also agrees that during the Lock-Up Period, the Company will not file any registration
statement, preliminary prospectus or prospectus, or any amendment or supplement thereto, under the Securities Act for any such
transaction or which registers, or offers for sale, Common Stock or any securities convertible into or exercisable or exchangeable
for Common Stock, except for a registration statement on Form S 8 relating to employee benefit plans.

 

    	-25-

    	 

    

 

(b)          During
the Lock-Up Period, the Company shall be prohibited from effecting or entering into an agreement to effect any issuance by the
Company or any of its Subsidiaries of Common Stock or Common Stock Equivalents (or a combination of units thereof) involving a
Variable Rate Transaction. “Variable Rate Transaction” means a transaction in which the Company (i) issues or
sells any debt or equity securities that are convertible into, exchangeable or exercisable for, or include the right to receive
additional shares of Common Stock either (A) at a conversion price, exercise price or exchange rate or other price that is based
upon and/or varies with the trading prices of or quotations for the shares of Common Stock at any time after the initial issuance
of such debt or equity securities, or (B) with a conversion, exercise or exchange price that is subject to being reset at some
future date after the initial issuance of such debt or equity security or upon the occurrence of specified or contingent events
directly or indirectly related to the business of the Company or the market for the Common Stock or (ii) enters into any agreement,
including, but not limited to, an equity line of credit or an at-the-market offering agreement, whereby the Company may issue securities
at a future determined price.

 

4.12        Equal
Treatment of Purchasers. No consideration (including any modification of any Transaction Document) 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
is also offered to all of the parties to this Agreement. For clarification purposes, this provision constitutes a separate right
granted to each Purchaser by the Company and negotiated separately by each Purchaser, and is intended for the Company to treat
the Purchasers as a class and shall not in any way be construed as the Purchasers acting in concert or as a group with respect
to the purchase, disposition or voting of Securities or otherwise.

 

    	-26-

    	 

    

 

4.13        Certain
Transactions and Confidentiality. Each Purchaser, severally and not jointly with the other Purchasers, covenants that neither
it nor any Affiliate acting on its behalf or pursuant to any understanding with it will execute any purchases or sales, including
Short Sales of any of the Company’s securities during the period commencing with the execution of this Agreement and ending
at such time that the transactions contemplated by this Agreement are first publicly announced pursuant to the initial press release
as described in Section 4.4. Each Purchaser, severally and not jointly with the other Purchasers, covenants that until such time
as the transactions contemplated by this Agreement are publicly disclosed by the Company pursuant to the initial press release
as described in Section 4.4, such Purchaser will maintain the confidentiality of the existence and terms of this transaction. Notwithstanding
the foregoing and notwithstanding anything contained in this Agreement to the contrary, the Company expressly acknowledges and
agrees that (i) no Purchaser makes any representation, warranty or covenant hereby that it will not engage in effecting transactions
in any securities of the Company after the time that the transactions contemplated by this Agreement are first publicly announced
pursuant to the initial press release as described in Section 4.4, (ii) no Purchaser shall be restricted or prohibited from effecting
any transactions in any securities of the Company in accordance with applicable securities laws from and after the time that the
transactions contemplated by this Agreement are first publicly announced pursuant to the initial press release as described in
Section 4.4 and (iii) no Purchaser shall have any duty of confidentiality to the Company or its Subsidiaries after the issuance
of the initial press release as described in Section 4.4. Notwithstanding the foregoing, in the case of a Purchaser that is a multi-managed
investment vehicle whereby separate portfolio managers manage separate portions of such Purchaser’s assets and the portfolio
managers have no direct knowledge of the investment decisions made by the portfolio managers managing other portions of such Purchaser’s
assets, the covenant set forth above shall only apply with respect to the portion of assets managed by the portfolio manager that
made the investment decision to purchase the Securities covered by this Agreement.

 

4.14        Capital
Changes. Until the one year anniversary of the Closing Date, other than a stock split or reclassification that is effected
to maintain the listing of the Common Stock on the primary Trading Market, the Company shall not undertake a reverse or forward
stock split or reclassification of the Common Stock without the prior written consent of the Purchasers holding a majority in interest
of the Shares.

 

4.15        Exercise
Procedures. The form of Notice of Exercise included in the Warrants set forth the totality of the procedures required of the
Purchasers in order to exercise the Warrants. No additional legal opinion, other information or instructions shall be required
of the Purchasers to exercise their Warrants. Without limiting the preceding sentences, no ink-original Notice of Exercise shall
be required, nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice of Exercise form be required
in order to exercise the Warrants. The Company shall honor exercises of the Warrants and shall deliver Warrant Shares in accordance
with the terms, conditions and time periods set forth in the Transaction Documents.

4.16        Transfer
Restrictions.

 

(a)          Certificates
evidencing the Warrant Shares issuable upon exercise of the Warrants shall not contain any Securities Act legend: (i) while a registration
statement covering the resale of such security is effective under the Securities Act, (ii) following any sale of such Warrant Shares
pursuant to Rule 144, (iii) if such Warrant Shares are eligible for sale under Rule 144, without the requirement for the Company
to be in compliance with the current public information required under Rule 144 as to such Warrant Shares and without volume or
manner-of-sale restrictions or (iv) if such legend is not required under applicable requirements of the Securities Act (including
judicial interpretations and pronouncements issued by the staff of the Commission). The Company shall cause its counsel to issue
a legal opinion to the Transfer Agent promptly after the Effective Date if required by the Transfer Agent to effect the removal
of the legend hereunder. If a Warrant is exercised at a time when there is an effective registration statement to cover the resale
of the Warrant Shares issuable in respect thereof, or if such Warrant Shares may be sold under Rule 144 and the Company is then
in compliance with the current public information required under Rule 144, or if such Warrant Shares may be sold under Rule 144
without the requirement for the Company to be in compliance with the current public information required under Rule 144 as to such
Warrant Shares and without volume or manner-of-sale restrictions or if such legend is not otherwise required under applicable requirements
of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the Commission) then such Warrant
Shares shall be issued free of all legends. The Company agrees that following the Effective Date or at such time as such legend
is no longer required under this Section 4.16(c), it will, no later than three Trading Days following the delivery by a Purchaser
to the Company or the Transfer Agent of a certificate representing Warrant Shares issued with a restrictive legend (such third
Trading Day, the “Legend Removal Date”) deliver or cause to be delivered to such Purchaser a certificate representing
such shares that is free from all restrictive and other legends. The Company may not make any notation on its records or give instructions
to the Transfer Agent that enlarge the restrictions on transfer set forth in this Section 4. Certificates for such Warrant Shares
subject to legend removal hereunder shall be transmitted by the Transfer Agent to the Purchaser by crediting the account of the
Purchaser’s prime broker with the Depository Trust Company System as directed by such Purchaser.

 

(b)          In
addition to such Purchaser’s other available remedies, the Company shall pay to a Purchaser, in cash, as partial liquidated
damages and not as a penalty, for each $1,000 of Warrant Shares (based on the VWAP of the Common Stock on the date such Warrant
Shares are submitted to the Transfer Agent) delivered for removal of the restrictive legend and subject to Section 4.16(c), $10
per Trading Day for each Trading Day after the Legend Removal Date until such certificate is delivered without a legend. Nothing
herein shall limit such Purchaser’s right to pursue actual damages for the Company’s failure to deliver certificates
representing any Securities as required by the Transaction Documents, and such Purchaser shall have the right to pursue all remedies
available to it at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief.

5.1          Termination.
This Agreement may be terminated by any Purchaser, as to such Purchaser’s obligations hereunder only and without any effect
whatsoever on the obligations between the Company and the other Purchasers, by written notice to the other parties, if the Closing
has not been consummated on or before June 30, 2015; provided, however, that no such termination will affect the

in the case of an amendment, by the Company and the Purchasers who purchased at least a majority in interest of the Shares based
on the initial Subscription Amounts hereunder or, in the case of a waiver, by the party against whom enforcement of any such waived
provision is sought. No waiver of any default with respect to any provision, condition or requirement of this Agreement shall be
deemed to be a continuing waiver in the future or a waiver of any subsequent default or a waiver of any other provision, condition
or requirement hereof, nor shall any delay or omission of any party to exercise any right hereunder in any manner impair the exercise
of any such right.

 

5.6          Headings.

and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and their successors and permitted
assigns. The Company may not assign this Agreement or any rights or obligations hereunder without the prior written consent of
each Purchaser (other than by merger). Any Purchaser may assign any or all of its rights under this Agreement to any Person to
whom such Purchaser assigns or transfers any Securities, provided that such transferee agrees in writing to be bound, with respect
to the transferred Securities, by the provisions of the Transaction Documents that apply to the “Purchasers.”

 

    	-29-

    	 

    

 

5.8          No
Third-Party Beneficiaries. The Placement Agent shall be the third party beneficiary of the representations and warranties of
the Purchasers in Section 3.2. This Agreement is intended for the benefit of the parties hereto and their respective successors
and permitted assigns and is not for the benefit of, nor may any provision hereof be enforced by, any other Person, except as otherwise
set forth in Section 4.8 and this Section 5.8.

 

5.9          Governing
Law. All questions concerning the construction, validity, enforcement and interpretation of the Transaction Documents shall
be governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the
principles of conflicts of law thereof. Each party agrees that all legal proceedings concerning the interpretations, enforcement
and defense of the transactions contemplated by this Agreement and any other Transaction Documents (whether brought against a party
hereto or its respective affiliates, directors, officers, shareholders, partners, members, employees or agents) shall be commenced
exclusively in the state and federal courts sitting in the City of New York. Each party hereby irrevocably submits to the exclusive
jurisdiction of the state and federal courts sitting in the City of New York, Borough of Manhattan for the adjudication of any
dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein (including with respect
to the enforcement of any of the Transaction Documents), and hereby irrevocably waives, and agrees not to assert in any suit, action
or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding
is improper or is an inconvenient venue for such proceeding. Each party hereby irrevocably waives personal service of process and
consents to process being served in any such suit, action or proceeding by mailing a copy thereof via registered or certified mail
or overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Agreement
and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein
shall be deemed to limit in any way any right to serve process in any other manner permitted by law. If either party shall commence
an action, suit or proceeding to enforce any provisions of the Transaction Documents, then, in addition to the obligations of the
Company under Section 4.8, the prevailing party in such action, suit or proceeding shall be reimbursed by the other party for its
reasonable attorneys’ fees and other costs and expenses incurred with the investigation, preparation and prosecution of such
action or proceeding.

 

5.10        Survival.
The representations and warranties contained herein shall survive the Closing and the delivery of the Securities.

 

5.11        Execution.
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 each other party, it being
understood that the 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.

 

    	-30-

    	 

    

 

5.12         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.

 

5.13         Rescission
and Withdrawal Right. Notwithstanding anything to the contrary contained in (and without limiting any similar provisions of)
any of the other Transaction Documents, whenever any Purchaser exercises a right, election, demand or option under a Transaction
Document and the Company does not timely perform its related obligations within the periods therein provided, then such Purchaser
may rescind or withdraw, in its sole discretion from time to time upon written notice to the Company, any relevant notice, demand
or election in whole or in part without prejudice to its future actions and rights; provided, however, that in the
case of a rescission of an exercise of a Warrant, the applicable Purchaser shall be required to return any shares of Common Stock
subject to any such rescinded exercise notice concurrently with the return to such Purchaser of the aggregate exercise price paid
to the Company for such shares and the restoration of such Purchaser’s right to acquire such shares pursuant to such Purchaser’s
Warrant (including, issuance of a replacement warrant certificate evidencing such restored right).

 

5.14         Replacement
of Securities. If any certificate or instrument evidencing any Securities is mutilated, lost, stolen or destroyed, the Company
shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof (in the case of mutilation), or
in lieu of and substitution therefor, a new certificate or instrument, but only upon receipt of evidence reasonably satisfactory
to the Company of such loss, theft or destruction. The applicant for a new certificate or instrument under such circumstances shall
also pay any reasonable third-party costs (including customary indemnity) associated with the issuance of such replacement Securities.

 

5.15         Remedies.
In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages, each of
the Purchasers and the Company will be entitled to specific performance under the Transaction Documents. The parties agree that
monetary damages may not be adequate compensation for any loss incurred by reason of any breach of obligations contained in the
Transaction Documents and hereby agree to waive and not to assert in any action for specific performance of any such obligation
the defense that a remedy at law would be adequate.

 

5.16         Payment
Set Aside. To the extent that the Company makes a payment or payments to any Purchaser pursuant to any Transaction Document
or a Purchaser enforces or exercises its rights thereunder, and such payment or payments or the proceeds of such enforcement or
exercise or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside, recovered from,
disgorged by or are required to be refunded, repaid or otherwise restored to the Company, a trustee, receiver or any other Person
under any law (including, without limitation, any bankruptcy law, state or federal law, common law or equitable cause of action),
then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived
and continued in full force and effect as if such payment had not been made or such enforcement or setoff had not occurred.

 

    	-31-

    	 

    

 

5.17         Independent
Nature of Purchasers’ Obligations and Rights. The obligations of each Purchaser under any Transaction Document are several
and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance
or non-performance of the obligations of any other Purchaser under any Transaction Document. Nothing contained herein or in any
other Transaction Document, and no action taken by any Purchaser pursuant hereto or thereto, shall be deemed to constitute the
Purchasers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers
are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction
Documents. Each Purchaser shall be entitled to independently protect and enforce its rights including, without limitation, the
rights arising out of this Agreement or out of the other Transaction Documents, and it shall not be necessary for any other Purchaser
to be joined as an additional party in any proceeding for such purpose. Each Purchaser has been represented by its own separate
legal counsel in its review and negotiation of the Transaction Documents. For reasons of administrative convenience only, each
Purchaser and its respective counsel have chosen to communicate with the Company through counsel for the Placement Agent. Such
counsel does not represent any of the Purchasers and only represents the Placement Agent. The Company has elected to provide all
Purchasers with the same terms and Transaction Documents for the convenience of the Company and not because it was required or
requested to do so by any of the Purchasers. It is expressly understood and agreed that each provision contained in this Agreement
and in each other Transaction Document is between the Company and a Purchaser, solely, and not between the Company and the Purchasers
collectively and not between and among the Purchasers.

 

5.18         Liquidated
Damages. The Company’s obligations to pay any partial liquidated damages or other amounts owing under the Transaction
Documents is a continuing obligation of the Company and shall not terminate until all unpaid partial liquidated damages and other
amounts have been paid notwithstanding the fact that the instrument or security pursuant to which such partial liquidated damages
or other amounts are due and payable shall have been canceled.

 

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

 

5.20         Construction.
The parties agree that each of them and/or their respective counsel have reviewed and had an opportunity to revise the Transaction
Documents and, therefore, the normal rule of construction to the effect that any ambiguities are to be resolved against the drafting
party shall not be employed in the interpretation of the Transaction Documents or any amendments thereto. In addition, each and
every reference to share prices and shares of Common Stock in any Transaction Document shall be subject to adjustment for reverse
and forward stock splits, stock dividends, stock combinations and other similar transactions of the Common Stock that occur after
the date of this Agreement.

 

    	-32-

    	 

    

 

5.21         WAIVER
OF JURY TRIAL. IN ANY ACTION, SUIT, OR PROCEEDING IN ANY JURISDICTION BROUGHT BY ANY PARTY AGAINST ANY OTHER PARTY, THE PARTIES
EACH KNOWINGLY AND INTENTIONALLY, TO THE GREATEST EXTENT PERMITTED BY APPLICABLE LAW, HEREBY ABSOLUTELY, UNCONDITIONALLY, IRREVOCABLY
AND EXPRESSLY WAIVES FOREVER TRIAL BY JURY.

Schedule 3.1(d)

 

As disclosed in the Registration
Statement or the SEC filings incorporated by reference into the Registration Statement, the investors in the Company’s March
2014 private placement (the “2014 Investors”) were granted the right to participate in any equity offering (including
the offering evidenced by this Agreement) that the Company completes prior to March 12, 2016, with their participation right being
equal to, on an aggregate basis, of up to 50% of the equity offering (the “Participation Right”). The Participation
Right requires the Company to notify the 2014 Investors of the equity issuance, with the 2014 Investors generally having 5 business
days to elect to participate in the equity offering. In connection with the transactions contemplated by this Agreement, on June
9, 2015, the Company sent a notification via email to the 2014 Investors informing them that the Company intended to enter into
a securities purchase agreement with new investors for a registered direct offering with, among other things, a purchase price
per common share that will be at a discount to the trading price.

COMMON STOCK PURCHASE WARRANT

 

ROCK CREEK PHARMACEUTICALS, INC.

 

	
        Warrant Shares:
	Initial Exercise Date: December 20, 2015

 

THIS COMMON STOCK PURCHASE
WARRANT (the “Warrant”) certifies that, for value received,                           
or its assigns (the “Holder”) is entitled, upon the terms and subject to the limitations on exercise and the
conditions hereinafter set forth, at any time on or after December 20, 2015 (the “Initial Exercise Date”) and
on or prior to the close of business on the five (5) year anniversary of the Initial Exercise Date (the “Termination
Date”) but not thereafter, to subscribe for and purchase from Rock Creek Pharmaceuticals, Inc., a Delaware corporation
(the “Company”), up to              shares (as subject
to adjustment hereunder, the “Warrant Shares”) of Common Stock. The purchase price of one share of Common Stock
under this Warrant shall be equal to the Exercise Price, as defined in Section 2(b).

 

Definitions. Capitalized terms used
and not otherwise defined herein shall have the meanings set forth in that certain Securities Purchase Agreement (the “Purchase
Agreement”), dated June 16, 2015 (the “Subscription Date”), among the Company and the purchasers signatory
thereto.

 

Exercise.

 

Exercise of the purchase
rights represented by this Warrant may be made, in whole or in part, at any time or times on or after the Initial Exercise Date
and on or before the Termination Date by delivery to the Company (or such other office or agency of the Company as it may designate
by notice in writing to the registered Holder at the address of the Holder appearing on the books of the Company) of a duly executed
copy of the Notice of Exercise in the form annexed hereto by facsimile or email. Within three (3) Trading Days following the
date of exercise as aforesaid, the Holder shall deliver the aggregate Exercise Price for the shares specified in the applicable
Notice of Exercise by wire transfer or cashier’s check drawn on a United States bank unless the cashless exercise procedure
specified in Section 2(c) below is permitted and is specified in the applicable Notice of Exercise. No ink-original Notice
of Exercise shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice of
Exercise form be required.  Notwithstanding anything herein to the contrary, the Holder shall not be required to physically
surrender this Warrant to the Company until the Holder has purchased all of the Warrant Shares available hereunder and the Warrant
has been exercised in full, in which case, the Holder shall surrender this Warrant to the Company for cancellation within three
(3) Trading Days of the date the final Notice of Exercise is delivered to the Company. Partial exercises of this Warrant resulting
in purchases of a portion of the total number of Warrant Shares available hereunder shall have the effect of lowering the outstanding
number of Warrant Shares purchasable hereunder in an amount equal to the applicable number of Warrant Shares purchased.  The
Holder and the Company shall maintain records showing the number of Warrant Shares purchased and the date of such purchases. The
Company shall deliver any objection to any Notice of Exercise within one (1) Business Day of receipt of such notice.  The
Holder and any assignee, by acceptance of this Warrant, acknowledge and agree that, by reason of the provisions of this paragraph,
following the purchase of a portion of the Warrant Shares hereunder, the number of Warrant Shares available for purchase hereunder
at any given time may be less than the amount stated on the face hereof.

 

    	-1-

    	 

    

 

Exercise Price.
The exercise price per share of the Common Stock under this Warrant shall be $2.83, subject to adjustment hereunder (the “Exercise
Price”).

 

Cashless Exercise.
If at any time after the six (6) month anniversary of the Subscription Date, there is no effective Registration Statement
at the time of exercise hereof registering, or no current prospectus available for, the resale of the Warrant Shares by the Holder,
then this Warrant may also be exercised, in whole or in part, at such time by means of a “cashless exercise” in which
the Holder shall be entitled to receive a number of Warrant Shares equal to the quotient obtained by dividing [(A-B) (X)] by (A),
where:

 

(A) = the VWAP on the Trading Day
immediately preceding the date on which Holder elects to exercise this Warrant by means of a “cashless exercise,” as
set forth in the applicable Notice of Exercise;

 

(B) = the Exercise Price of this
Warrant, as adjusted hereunder; and

 

(X) = the number of Warrant Shares
that would be issuable upon exercise of this Warrant in accordance with the terms of this Warrant if such exercise were by means
of a cash exercise rather than a cashless exercise.

 

“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, 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. (New York City 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 OTC Markets, Inc. (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 Holders of a majority in interest of the Securities then outstanding and reasonably acceptable to
the Company, the fees and expenses of which shall be paid by the Company.

Mechanics of Exercise.

 

Delivery of Warrant
Shares Upon Exercise. The Company shall cause the Warrant Shares purchased hereunder to be transmitted by the Transfer Agent
to the Holder by crediting the account of the Holder’s prime broker with The Depository Trust Company through its Deposit
or Withdrawal at Custodian system (“DWAC”) if the Company is then a participant in such system and either (A) there
is an effective registration statement permitting the issuance of the Warrant Shares to or resale of the Warrant Shares by Holder
or (B) this Warrant is being exercised via cashless exercise, and otherwise by physical delivery to the address specified
by the Holder in the Notice of Exercise by the date that is one (1) Trading Day after the delivery to the Company of the Notice
of Exercise (such date, the “Warrant Share Delivery Date”), provided that the Company shall not be obligated
to deliver Warrant Shares hereunder unless the Company has received the aggregate Exercise Price on or before the Warrant Share
Delivery Date.   The Warrant Shares shall be deemed to have been issued, and Holder or any other person so designated
to be named therein shall be deemed to have become a holder of record of such shares for all purposes, as of the date the Warrant
has been exercised, with payment to the Company of the Exercise Price (or by cashless exercise, if permitted) and all taxes required
to be paid by the Holder, if any, pursuant to Section 2(d)(vi) prior to the issuance of such shares, having been paid.
If the Company fails for any reason to deliver to the Holder the Warrant Shares subject to a Notice of Exercise by the Warrant
Share Delivery Date, the Company shall pay to the Holder, in cash, as liquidated damages and not as a penalty, for each $1,000
of Warrant Shares subject to such exercise (based on the VWAP of the Common Stock on the date of the applicable Notice of Exercise),
$10 per Trading Day for each Trading Day after such Warrant Share Delivery Date until such Warrant Shares are delivered or Holder
rescinds such exercise.  The obligation of the Company to pay liquidated damages under this Section 2(d)(i) is subject
to delivery by the Holder of the aggregate Exercise Price in accordance with the terms of Section 2(a) herein.

 

Delivery of New Warrants
Upon Exercise. If this Warrant shall have been exercised in part, the Company shall, at the request of a Holder and upon surrender
of this Warrant certificate, at the time of delivery of the Warrant Shares, deliver to the Holder a new Warrant evidencing the
rights of the Holder to purchase the unpurchased Warrant Shares called for by this Warrant, which new Warrant shall in all other
respects be identical with this Warrant.

 

Rescission Rights.
If the Company fails to cause the Transfer Agent to transmit to the Holder the Warrant Shares pursuant to Section 2(d)(i) by
the Warrant Share Delivery Date, then the Holder will have the right to rescind such exercise. The right of rescission of the Holder
under this Section 2(d)(iii) is subject to delivery by the Holder of the aggregate Exercise Price in accordance with
the terms of Section 2(a) herein

 

Compensation for Buy-In
on Failure to Timely Deliver Warrant Shares Upon Exercise. In addition to any other rights available to the Holder, if the
Company fails to cause the Transfer Agent to transmit to the Holder the Warrant Shares pursuant to an exercise on or before the
Warrant Share Delivery Date, and if after such date the Holder is required by its broker to purchase (in an open market transaction
or otherwise) or the Holder’s brokerage firm otherwise purchases, shares of Common Stock to deliver in satisfaction of a
sale by the Holder of the Warrant Shares which the Holder anticipated receiving upon such exercise (a “Buy-In”),
then the Company shall (A) pay in cash to the Holder the amount, if any, by which (x) the Holder’s total purchase
price (including brokerage commissions, if any) for the shares of Common Stock so purchased exceeds (y) the amount obtained
by multiplying (1) the number of Warrant Shares that the Company was required to deliver to the Holder in connection with
the exercise at issue times (2) the price at which the sell order giving rise to such purchase obligation was executed, and
(B) at the option of the Holder, either reinstate the portion of the Warrant and equivalent number of Warrant Shares for which
such exercise was not honored (in which case such exercise shall be deemed rescinded) or deliver to the Holder the number of shares
of Common Stock that would have been issued had the Company timely complied with its exercise and delivery obligations hereunder. 
For example, if the Holder purchases Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an
attempted exercise of shares of Common Stock with an aggregate sale price giving rise to such purchase obligation of $10,000, under
clause (A) of the immediately preceding sentence the Company shall be required to pay the Holder $1,000. The Holder shall
provide the Company written notice indicating the amounts payable to the Holder in respect of the Buy-In and, upon request of the
Company, evidence of the amount of such loss.  Nothing herein shall limit a Holder’s right to pursue any other remedies
available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive
relief with respect to the Company’s failure to timely deliver shares of Common Stock upon exercise of the Warrant as required
pursuant to the terms hereof. The obligation of the Company to pay compensation for Buy-In under this Section 2(d)(iv) is
subject to delivery by the Holder of the aggregate Exercise Price in accordance with the terms of Section 2(a) herein

 

    	-3-

    	 

    

 

No Fractional Shares
or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this Warrant. 
As to any fraction of a share which the 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 final fraction in an amount equal to such fraction multiplied by
the Exercise Price or round up to the next whole share.

 

Charges, Taxes and
Expenses. Issuance of Warrant Shares shall be made without charge to the Holder for any issue or transfer tax or other incidental
expense in respect of the issuance of such Warrant Shares, all of which taxes and expenses shall be paid by the Company, and such
Warrant Shares shall be issued in the name of the Holder or in such name or names as may be directed by the Holder; provided, however,
that in the event Warrant Shares are to be issued in a name other than the name of the Holder, this Warrant when surrendered for
exercise shall be accompanied by the Assignment Form attached hereto duly executed by the Holder and the Company may require,
as a condition thereto, the payment of a sum sufficient to reimburse it for any transfer tax incidental thereto.  The Company
shall pay all Transfer Agent fees required for same-day processing of any Notice of Exercise and all fees to the Depository Trust
Company (or another established clearing corporation performing similar functions) required for same-day electronic delivery of
the Warrant Shares.

 

Closing of Books.
The Company will not close its stockholder books or records in any manner which prevents the timely exercise of this Warrant, pursuant
to the terms hereof.

Holder’s Exercise
Limitations. The Company shall not effect any exercise of this Warrant, and a Holder shall not have the right to exercise any
portion of this Warrant, pursuant to Section 2 or otherwise, to the extent that after giving effect to such issuance after
exercise as set forth on the applicable Notice of Exercise, the Holder (together with the Holder’s Affiliates, and any other
Persons acting as a group together with the Holder or any of the 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 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 (i) exercise of the remaining, nonexercised portion of this Warrant beneficially owned by the
Holder or any of its Affiliates and (ii) exercise or conversion of the unexercised or nonconverted portion of any other securities
of the Company (including, without limitation, any other  Common Stock Equivalents) subject to a limitation on conversion
or exercise analogous to the limitation contained herein beneficially owned by the Holder or any of its Affiliates.  Except
as set forth in the preceding sentence, for purposes of this Section 2(e), beneficial ownership shall be calculated in accordance
with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder, it being acknowledged
by the Holder that the Company is not representing to the Holder that such calculation is in compliance with Section 13(d) of
the Exchange Act and the Holder is solely responsible for any schedules required to be filed in accordance therewith.  
To the extent that the limitation contained in this Section 2(e) applies, the determination of whether this Warrant is
exercisable (in relation to other securities owned by the Holder together with any Affiliates) and of which portion of this Warrant
is exercisable shall be in the sole discretion of the Holder, and the submission of a Notice of Exercise shall be deemed to be
the Holder’s determination of whether this Warrant is exercisable (in relation to other securities owned by the Holder together
with any Affiliates) and of which portion of this Warrant is exercisable, in each case subject to the Beneficial Ownership Limitation,
and the Company shall have no obligation to verify or confirm the accuracy of such determination and shall have no liability for
exercises of the Warrant that are not in compliance with the Beneficial Ownership Limitation (other than to the extent that information
on the number of outstanding shares of Common Stock of the Company is provided by the Company and relied upon by the Holder).  
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 and the rules and regulations promulgated thereunder and the Company shall have no obligation to verify or
confirm the accuracy of such determination and shall have no liability for exercises of the Warrant that are not in compliance
with the Beneficial Ownership Limitation.  For purposes of this Section 2(e), in determining the number of outstanding
shares of Common Stock, a 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 filed with the Commission, as the case may be, (B) a more recent public announcement
by the Company or (C) a more recent written notice by the Company or the Transfer Agent setting forth the number of shares
of Common Stock outstanding.  Upon the written or oral request of a Holder, the Company shall within two Trading Days confirm
orally and in writing to the 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 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 Holder, upon not less than 61 days’ prior notice to the Company, may increase or decrease the Beneficial Ownership Limitation
provisions of this Section 2(e), provided that the Beneficial Ownership Limitation in no event exceeds 4.99% 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 Holder and the provisions of this Section 2(e) 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 paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 2(e) to
correct this paragraph (or any portion hereof) which may be defective or inconsistent with the intended Beneficial Ownership Limitation
herein contained or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitations
contained in this paragraph shall apply to a successor holder of this Warrant.

Certain Adjustments.

 

Subsequent Issuances.
The Exercise Price shall be adjusted from time to time as follows:

 

(i)  Adjustment
upon Issuance of shares of Common Stock. If and whenever on or after the Subscription Date and prior to the six (6) month anniversary
of the Subscription Date, the Company issues or sells, or in accordance with this Section 3 is deemed to have issued or sold, any
shares of Common Stock (including the issuance or sale of shares of Common Stock owned or held by or for the account of the Company,
but excluding shares of Common Stock deemed to have been issued by the Company in connection with any Excluded Securities (as defined
below) (the "Additional Shares") for a consideration per share (the "New Issuance Price") less
than a price (the "Applicable Price") equal to the Exercise Price in effect immediately prior to such issue or
sale or deemed issuance or sale (the foregoing a "Dilutive Issuance"), then immediately after such Dilutive Issuance,
the Exercise Price then in effect shall be reduced to the lowest price per share at which any share of Common Stock was issued
or sold or deemed to be issued or sold

 

For purposes
of determining the adjusted Exercise Price under this Section 3(a), the following shall be applicable:

 

(ii) Issuance
of Options. If the Company in any manner grants any Options (as defined below) and the lowest price per share for which one
share of Common Stock is issuable upon the exercise of any such Option or upon conversion, exercise or exchange of any Convertible
Securities (as defined below) issuable upon exercise of any such Option is less than the Applicable Price, then such share of Common
Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the granting or sale of
such Option for such price per share. For purposes of this Section 3(a)(ii), the "lowest price per share for which one share
of Common Stock is issuable upon exercise of such Options or upon conversion, exercise or exchange of such Convertible Securities
issuable upon exercise of any such Option" shall be equal to the sum of the lowest amounts of consideration (if any) received
or receivable by the Company with respect to any one share of Common Stock upon the granting or sale of the Option, upon exercise
of the Option and upon conversion, exercise or exchange of any Convertible Security issuable upon exercise of such Option less
any consideration paid or payable by the Company with respect to such one share of Common Stock upon the granting or sale of such
Option, upon exercise of such Option and upon conversion exercise or exchange of any Convertible Security issuable upon exercise
of such Option. No further adjustment of the Exercise Price shall be made upon the actual issuance of such shares of Common Stock
or of such Convertible Securities upon the exercise of such Options or upon the actual issuance of such shares of Common Stock
upon conversion, exercise or exchange of such Convertible Securities.

 

    	-6-

    	 

    

 

(iii) Issuance
of Convertible Securities. If the Company in any manner issues or sells any Convertible Securities and the lowest price per
share for which one share of Common Stock is issuable upon the conversion, exercise or exchange thereof is less than the Applicable
Price, then such share of Common Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the
time of the issuance or sale of such Convertible Securities for such price per share. For the purposes of this Section 3(a)(iii),
the "lowest price per share for which one share of Common Stock is issuable upon the conversion, exercise or exchange thereof"
shall be equal to the sum of the lowest amounts of consideration (if any) received or receivable by the Company with respect to
one share of Common Stock upon the issuance or sale of the Convertible Security and upon conversion, exercise or exchange of such
Convertible Security less any consideration paid or payable by the Company with respect to such one share of Common Stock upon
the issuance or sale of such Convertible Security and upon conversion, exercise or exchange of such Convertible Security. No further
adjustment of the Exercise Price or number of Warrant Shares shall be made upon the actual issuance of such shares of Common Stock
upon conversion, exercise or exchange of such Convertible Securities, and if any such issue or sale of such Convertible Securities
is made upon exercise of any Options for which adjustment of this Warrant has been or is to be made pursuant to other provisions
of this Section 3(a), no further adjustment of the Exercise Price shall be made by reason of such issue or sale.

 

(iv) Change
in Option Price or Rate of Conversion. If the purchase price provided for in any Options, the additional consideration, if
any, payable upon the issue, conversion, exercise or exchange of any Convertible Securities, or the rate at which any Convertible
Securities are convertible into or exercisable or exchangeable for shares of Common Stock increases or decreases at any time, the
Exercise Price in effect at the time of such increase or decrease shall be adjusted to the Exercise Price which would have been
in effect at such time had such Options or Convertible Securities provided for such increased or decreased purchase price, additional
consideration or increased or decreased conversion rate, as the case may be, at the time initially granted, issued or sold. For
purposes of this Section 3(a)(iv), if the terms of any Option or Convertible Security that was outstanding as of the date of issuance
of this Warrant are increased or decreased in the manner described in the immediately preceding sentence, then such Option or Convertible
Security and the shares of Common Stock deemed issuable upon exercise, conversion or exchange thereof shall be deemed to have been
issued as of the date of such increase or decrease. No adjustment pursuant to this Section 3(a) shall be made if such adjustment
would result in an increase of the Exercise Price then in effect.

 

    	-7-

    	 

    

 

(v) Calculation
of Consideration Received. In case any Option is issued in connection with the issue or sale of other securities of the Company,
together comprising one integrated transaction, (x) the Options will be deemed to have been issued for the Option Value of such
Options and (y) the other securities issued or sold in such integrated transaction shall be deemed to have been issued for the
difference of (I) the aggregate consideration received by the Company less any consideration paid or payable by the Company pursuant
to the terms of such other securities of the Company, less (II) the Option Value. If any shares of Common Stock, Options or Convertible
Securities are issued or sold or deemed to have been issued or sold for cash, the consideration received therefor will be deemed
to be the net amount received by the Company therefor. If any shares of Common Stock, Options or Convertible Securities are issued
or sold for a consideration other than cash, the amount of such consideration received by the Company will be the fair value of
such consideration, except where such consideration consists of securities, in which case the amount of consideration received
by the Company will be the Closing Sale Price of such security on the date of receipt. If any shares of Common Stock, Options or
Convertible Securities are issued to the owners of the non-surviving entity in connection with any merger in which the Company
is the surviving entity, the amount of consideration therefor will be deemed to be the fair value of such portion of the net assets
and business of the non-surviving entity as is attributable to such shares of Common Stock, Options or Convertible Securities,
as the case may be. The fair value of any consideration other than cash or securities will be determined jointly by the Company
and the holder of a least a majority in interest of the number of Warrant Shares issuable upon exercise of the Warrants then outstanding
(the “Required Holders”). If such parties are unable to reach agreement within ten (10) days after the occurrence
of an event requiring valuation (the "Valuation Event"), the fair value of such consideration will be determined
within five (5) Trading Days after the tenth (10th) day following the Valuation Event by an independent, reputable appraiser jointly
selected by the Company and the Required Holders. The determination of such appraiser shall be final and binding upon all parties
absent manifest error and the fees and expenses of such appraiser shall be borne by the Company.

 

(v) Record
Date. If the Company takes a record of the holders of shares of Common Stock for the purpose of entitling them (A) to receive
a dividend or other distribution payable in shares of Common Stock, Options or in Convertible Securities or (B) to subscribe for
or purchase shares of Common Stock, Options or Convertible Securities, then such record date will be deemed to be the date of the
issue or sale of the shares of Common Stock deemed to have been issued or sold upon the declaration of such dividend or the making
of such other distribution or the date of the granting of such right of subscription or purchase, as the case may be.

 

Voluntary Adjustment
By Company. The Company may at any time during the term of this Warrant reduce the then current Exercise Price to any amount
and for any period of time deemed appropriate by the Board of Directors of the Company.

 

Stock Dividends
and Splits. If the Company, at any time while this Warrant is outstanding: (i) pays a stock dividend or otherwise makes
a distribution or distributions on shares of its Common Stock or any other equity or equity equivalent securities payable in shares
of Common Stock (which, for avoidance of doubt, shall not include any shares of Common Stock issued by the Company upon exercise
of this Warrant), (ii) subdivides outstanding shares of Common Stock into a larger number of shares, (iii) combines (including
by way of reverse stock split) outstanding shares of Common Stock into a smaller number of shares, or (iv) issues by reclassification
of shares of the Common Stock any shares of capital stock of the Company, then in each case the Exercise Price shall be multiplied
by a fraction of which the numerator shall be the number of shares of Common Stock (excluding treasury shares, if any) outstanding
immediately before such event and of which the denominator shall be the number of shares of Common Stock outstanding immediately
after such event, and the number of shares issuable upon exercise of this Warrant shall be proportionately adjusted such that the
aggregate Exercise Price of this Warrant shall remain unchanged.  Any adjustment made pursuant to this Section 3(a) shall
become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution
and shall become effective immediately after the effective date in the case of a subdivision, combination or re-classification.

 

    	-8-

    	 

    

 

Subsequent Rights
Offerings. In addition to any adjustments pursuant to Section 3(a) above, if at any time the Company grants, issues
or sells any Common Stock Equivalents or rights to purchase stock, warrants, securities or other property pro rata to the record
holders of any class of shares of Common Stock (the “Purchase Rights”), then the Holder will be entitled to
acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired
if the Holder had held the number of shares of Common Stock acquirable upon complete exercise of this Warrant (without regard to
any limitations on exercise hereof, including without limitation, the Beneficial Ownership Limitation) immediately before the date
on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as
of which the record holders of shares of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights
(provided, however, to the extent that the Holder’s right to participate in any such Purchase Right would result in the Holder
exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate in such Purchase Right to such
extent (or beneficial ownership of such shares of Common Stock as a result of such Purchase Right to such extent) and such Purchase
Right to such extent shall be held in abeyance for the Holder until such time, if ever, as its right thereto would not result in
the Holder exceeding the Beneficial Ownership Limitation).

 

Pro Rata Distributions.
During such time as this Warrant is outstanding, if the Company shall declare or make any dividend or other distribution of its
assets (or rights to acquire its assets) to holders of shares of Common Stock, by way of return of capital or otherwise (including,
without limitation, any distribution of cash, stock or other securities, property or options by way of a dividend, spin off, reclassification,
corporate rearrangement, scheme of arrangement or other similar transaction) (a “Distribution”), at any time
after the issuance of this Warrant, then, in each such case, the Holder shall be entitled to participate in such Distribution to
the same extent that the Holder would have participated therein if the Holder had held the number of shares of Common Stock acquirable
upon complete exercise of this Warrant (without regard to any limitations on exercise hereof, including without limitation, the
Beneficial Ownership Limitation) immediately before the date of which a record is taken for such Distribution, or, if no such record
is taken, the date as of which the record holders of shares of Common Stock are to be determined for the participation in such
Distribution (provided, however, to the extent that the Holder’s right to participate in any such Distribution
would result in the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate
in such Distribution to such extent (or in the beneficial ownership of any shares of Common Stock as a result of such Distribution
to such extent) and the portion of such Distribution shall be held in abeyance for the benefit of the Holder until such time, if
ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation). To the extent that this
Warrant has not been partially or completely exercised at the time of such Distribution, such portion of the Distribution shall
be held in abeyance for the benefit of the Holder until the Holder has exercised this Warrant.

Fundamental Transaction.
If, at any time while this Warrant is outstanding, (i) the Company, directly or indirectly, in one or more related transactions effects
any merger or consolidation of the Company with or into another Person, (ii) the Company, directly or indirectly, effects
any sale, lease, license, assignment, transfer, conveyance or other disposition of all or substantially all of its assets
in one or a series of related transactions, (iii) any, direct or indirect, purchase offer, tender offer or exchange offer
(whether by the Company or another Person) is completed pursuant to which holders of Common Stock are permitted to sell, tender
or exchange their shares for other securities, cash or property and has been accepted by the holders of 50% or more of the outstanding
Common Stock, (iv) the Company, directly or indirectly, in one or more related transactions effects any reclassification,
reorganization or recapitalization of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively
converted into or exchanged for other securities, cash or property, or (v) the Company, directly or indirectly, in one or
more related transactions consummates a stock or share purchase agreement or other business combination (including, without
limitation, a reorganization, recapitalization, spin-off or scheme of arrangement) with another Person or group of Persons
whereby such other Person or group acquires more than 50% of the outstanding shares of Common Stock (not including any
shares of Common Stock held by the other Person or other Persons making or party to, or associated or affiliated with the other
Persons making or party to, such stock or share purchase agreement or other business combination) (each a “Fundamental
Transaction”), then, upon any subsequent exercise of this Warrant, the Holder shall have the right to receive, for each
Warrant Share that would have been issuable upon such exercise immediately prior to the occurrence of such Fundamental Transaction,
at the option of the Holder (without regard to any limitation in Section 2(e) on the exercise of this Warrant), the number
of shares of Common Stock of the successor or acquiring corporation or of the Company, if it is the surviving corporation, and
any additional consideration (the “Alternate Consideration”) receivable as a result of such Fundamental Transaction
by a holder of the number of shares of Common Stock for which this Warrant is exercisable immediately prior to such Fundamental
Transaction (without regard to any limitation in Section 2(e) on the exercise of this Warrant).  For purposes of
any such exercise, the determination of the Exercise Price shall be appropriately adjusted to apply to such Alternate Consideration
based on the amount of Alternate Consideration issuable in respect of one share of Common Stock in such Fundamental Transaction,
and the Company shall apportion the Exercise Price among the Alternate Consideration in a reasonable manner reflecting the relative
value of any different components of the Alternate Consideration.  If holders of Common Stock are given any choice as to the
securities, cash or property to be received in a Fundamental Transaction, then the Holder shall be given the same choice as to
the Alternate Consideration it receives upon any exercise of this Warrant following such Fundamental Transaction.  The Company
shall cause any successor entity in a Fundamental Transaction in which the Company is not the survivor (the “Successor
Entity”) to assume in writing all of the obligations of the Company under this Warrant and the other Transaction Documents
in accordance with the provisions of this Section 3(e) pursuant to customary written agreements prior to such Fundamental
Transaction and shall, at the option of the Holder, deliver to the Holder in exchange for this Warrant a security of the Successor
Entity evidenced by a written instrument substantially similar in form and substance to this Warrant which is exercisable for a
corresponding number of shares of capital stock of such Successor Entity (or its parent entity) equivalent to the shares of Common
Stock acquirable and receivable upon exercise of this Warrant (without regard to any limitations on the exercise of this Warrant)
prior to such Fundamental Transaction, and with an exercise price which applies the exercise price hereunder to such shares of
capital stock (but taking into account the relative value of the shares of Common Stock pursuant to such Fundamental Transaction
and the value of such shares of capital stock, such number of shares of capital stock and such exercise price being for the purpose
of protecting the economic value of this Warrant immediately prior to the consummation of such Fundamental Transaction), and which
is reasonably satisfactory in form and substance to the Holder. Upon the occurrence of any such Fundamental Transaction, the Successor
Entity shall succeed to, and be substituted for, the Company (so that from and after the date of such Fundamental Transaction,
the provisions of this Warrant and the other Transaction Documents referring to the “Company” shall refer instead to
the Successor Entity), and the Successor Entity may exercise every right and power of the Company and shall assume all of the obligations
of the Company under this Warrant and the other Transaction Documents with the same effect as if such Successor Entity had been
named as the Company herein.

Calculations.
All calculations under this Section 3 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may
be. For purposes of this Section 3, the number of shares of Common Stock deemed to be issued and outstanding as of a given
date shall be the sum of the number of shares of Common Stock (excluding treasury shares, if any) issued and outstanding.

 

Notice to Holder.

 

Adjustment to Exercise
Price. Whenever the Exercise Price is adjusted pursuant to any provision of this Section 3, the Company shall promptly
mail to the Holder a notice setting forth the Exercise Price after such adjustment and any resulting adjustment to the number of
Warrant Shares and setting forth a brief statement of the facts requiring such adjustment.

 

Notice to Allow Exercise
by Holder. If, during the period in which this Warrant is outstanding, (A) the Company shall declare a dividend (or any
other distribution in whatever form) on the Common Stock, (B) the Company shall declare a special nonrecurring cash dividend
on or a redemption of the Common Stock, (C) the Company shall authorize the granting to all holders of the Common Stock rights
or warrants to subscribe for or purchase any shares of capital stock of any class or of any rights, (D) the approval of any
stockholders of the Company shall be required in connection with any reclassification of the Common Stock, any consolidation or
merger to which the Company is a party, any sale or transfer of all or substantially all of the assets of the Company, or any compulsory
share exchange whereby the Common Stock is converted into other securities, cash or property, or (E) the Company shall authorize
the voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Company, then, in each case, the Company
shall cause to be mailed to the Holder at its last address as it shall appear upon the Warrant Register of the Company, at least
20 calendar days prior to the applicable record or effective date hereinafter specified, a notice stating (x) the date on
which a record is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is
not to be taken, the date as of which the holders of the Common Stock of record to be entitled to such dividend, distributions,
redemption, rights or warrants are to be determined or (y) the date on which such reclassification, consolidation, merger,
sale, transfer or share exchange is expected to become effective or close, and the date as of which it is expected that holders
of the Common Stock of record shall be entitled to exchange their shares of the Common Stock for securities, cash or other property
deliverable upon such reclassification, consolidation, merger, sale, transfer or share exchange; provided that the failure to mail
such notice or any defect therein or in the mailing thereof shall not affect the validity of the corporate action required to be
specified in such notice.  To the extent that any notice provided hereunder constitutes, or contains, material, non-public
information regarding the Company or any of the Subsidiaries, the Company shall simultaneously file such notice with the Commission
pursuant to a Current Report on Form 8-K.  The Holder shall remain entitled to exercise this Warrant during the period
commencing on the date of such notice to the effective date of the event triggering such notice except as may otherwise be expressly
set forth herein.

pursuant to the Purchase Agreement and securities issued upon the exercise or conversion of those securities, and (iv) shares of
Common Stock issued or issuable by reason of a dividend, stock split or other distribution on shares of Common Stock (but only

provisions of this Warrant.

 

“Options”
means any rights, warrants or options to subscribe for or purchase shares of Common Stock or Convertible Securities.

 

“Option Value”
means the value of an Option based on the Black and Scholes Option Pricing model obtained from the “OV” function on

Option for pricing purposes and reflecting (i) a risk-free interest rate corresponding to the U.S. Treasury rate for a period equal
to the remaining term of the applicable Option as of the applicable date of determination, (ii) an expected volatility equal to

    	-12-

    	 

    

 

“Weighted
Average Price” means, for any security as of any date, the dollar volume-weighted average price for such security on
the principal market on which the Company’s Common Stock is then trading (the “Principal Market”) during the
period beginning at 9:30:01 a.m., New York time (or such other time as the Principal Market publicly announces is the official
open of trading), and ending at 4:00:00 p.m., New York time (or such other time as the Principal Market publicly announces is the
official close of trading), as reported by Bloomberg through its “Volume at Price” function or, if the foregoing does
not apply, the dollar volume-weighted average price of such security in the over-the-counter market on the electronic bulletin

publicly announces is the official open of trading), and ending at 4:00:00 p.m., New York time (or such other time as the Principal
Market publicly announces is the official close of trading), as reported by Bloomberg, or, if no dollar volume-weighted average
price is reported for such security by Bloomberg for such hours, the average of the highest closing bid price and the lowest closing

Average Price of such security on such date shall be the fair market value as mutually determined by the Company and the Holder.
All such determinations shall be appropriately adjusted for any stock dividend, stock split, stock combination or other similar
transaction during the applicable calculation period.

 

Transfer of Warrant.

 

Transferability.
Subject to compliance with any applicable securities laws and the conditions set forth in Section 4(d) hereof and to
the provisions of Section 4.1 of the Purchase Agreement, this Warrant and all rights hereunder (including, without limitation,
any registration rights) are transferable, in whole or in part, upon surrender of this Warrant at the principal office of the Company
or its designated agent, together with a written assignment of this Warrant substantially in the form attached hereto duly executed
by the Holder or its agent or attorney and funds sufficient to pay any transfer taxes payable upon the making of such transfer. 
Upon such surrender and, if required, such payment, the Company shall execute and deliver a new Warrant or Warrants in the name
of the assignee or assignees, as applicable, and in the denomination or denominations specified in such instrument of assignment,
and shall issue to the assignor a new Warrant evidencing the portion of this Warrant not so assigned, and this Warrant shall promptly
be cancelled.  Notwithstanding anything herein to the contrary, the Holder shall not be required to physically surrender
this Warrant to the Company unless the Holder has assigned this Warrant in full, in which case, the Holder shall surrender this
Warrant to the Company within three (3) Trading Days of the date the Holder delivers an assignment form to the Company assigning
this Warrant full.  The Warrant, if properly assigned in accordance herewith, may be exercised by a new holder for the
purchase of Warrant Shares without having a new Warrant issued.

 

New Warrants.
This Warrant may be divided or combined with other Warrants upon presentation hereof at the aforesaid office of the Company, together
with a written notice specifying the names and denominations in which new Warrants are to be issued, signed by the Holder or its
agent or attorney.  Subject to compliance with Section 4(a), as to any transfer which may be involved in such division
or combination, the Company shall execute and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants to be divided
or combined in accordance with such notice. All Warrants issued on transfers or exchanges shall be dated the initial issuance date
of this Warrant and shall be identical with this Warrant except as to the number of Warrant Shares issuable pursuant thereto.

 

    	-13-

    	 

    

 

Warrant Register.
The Company shall register this Warrant, upon records to be maintained by the Company for that purpose (the “Warrant Register”),
in the name of the record Holder hereof from time to time.  The Company may deem and treat the registered Holder of this Warrant
as the absolute owner hereof for the purpose of any exercise hereof or any distribution to the Holder, and for all other purposes,
absent actual notice to the contrary.

 

Transfer Restrictions.
If, at the time of the surrender of this Warrant in connection with any transfer of this Warrant, the transfer of this Warrant
shall not be either (i) registered pursuant to an effective registration statement under the Securities Act and under applicable
state securities or blue sky laws or (ii) eligible for resale without volume or manner-of-sale restrictions or current public
information requirements pursuant to Rule 144, the Company may require, as a condition of allowing such transfer, that the
Holder or transferee of this Warrant, as the case may be, comply with the provisions of Section 5.7 and Section 4.16(a) of
the Purchase Agreement.

 

Representation by
the Holder. The Holder, by the acceptance hereof, represents and warrants that it is acquiring this Warrant and, upon any exercise
hereof, will acquire the Warrant Shares issuable upon such exercise, for its own account and not with a view to or for distributing
or reselling such Warrant Shares or any part thereof in violation of the Securities Act or any applicable state securities law,
except pursuant to sales registered or exempted under the Securities Act.

 

Miscellaneous.

 

No Rights as Stockholder
Until Exercise. This Warrant does not entitle the Holder to any voting rights, dividends or other rights as a stockholder of
the Company prior to the exercise hereof as set forth in Section 2(d)(i), except as expressly set forth in Section 3.

 

Loss, Theft, Destruction
or Mutilation of Warrant. The Company covenants that upon receipt by the Company of evidence reasonably satisfactory to it
of the loss, theft, destruction or mutilation of this Warrant or any stock certificate relating to the Warrant Shares, and in case
of loss, theft or destruction, of indemnity or security reasonably satisfactory to it (which, in the case of the Warrant, shall
not include the posting of any bond), and upon surrender and cancellation of such Warrant or stock certificate, if mutilated, the
Company will make and deliver a new Warrant or stock certificate of like tenor and dated as of such cancellation, in lieu of such
Warrant or stock certificate.

 

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

 

    	-14-

    	 

    

 

Authorized Shares.

 

The Company covenants
that, during the period the Warrant is outstanding, it will reserve from its authorized and unissued Common Stock a sufficient
number of shares to provide for the issuance of the Warrant Shares upon the exercise of any purchase rights under this Warrant. 
The Company further covenants that its issuance of this Warrant shall constitute full authority to its officers who are charged
with the duty of executing stock certificates to execute and issue the necessary Warrant Shares upon the exercise of the purchase
rights under this Warrant.  The Company will take all such reasonable action as may be necessary to assure that such Warrant
Shares may be issued as provided herein without violation of any applicable law or regulation, or of any requirements of the Trading
Market upon which the Common Stock may be listed.  The Company covenants that all Warrant Shares which may be issued upon
the exercise of the purchase rights represented by this Warrant will, upon exercise of the purchase rights represented by this
Warrant and payment for such Warrant Shares in accordance herewith, be duly authorized, validly issued, fully paid and nonassessable
and free from all taxes, liens and charges created by the Company in respect of the issue thereof (other than taxes in respect
of any transfer occurring contemporaneously with such issue).

 

Except and to the extent
as waived or consented to by the Holder, the Company shall not by any action, including, without limitation, amending its certificate
of incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities
or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will
at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary
or appropriate to protect the rights of Holder as set forth in this Warrant against impairment.  Without limiting the generality
of the foregoing, the Company will (i) not increase the par value of any Warrant Shares above the amount payable therefor upon
such exercise immediately prior to such increase in par value, (ii) take all such action as may be necessary or appropriate
in order that the Company may validly and legally issue fully paid and nonassessable Warrant Shares upon the exercise of this Warrant
and (iii) use commercially reasonable efforts to obtain all such authorizations, exemptions or consents from any public regulatory
body having jurisdiction thereof, as may be, necessary to enable the Company to perform its obligations under this Warrant.

 

Before taking any action
which would result in an adjustment in the number of Warrant Shares for which this Warrant is exercisable or in the Exercise Price,
the Company shall obtain all such authorizations or exemptions thereof, or consents thereto, as may be necessary from any public
regulatory body or bodies having jurisdiction thereof.

 

Jurisdiction.
All questions concerning the construction, validity, enforcement and interpretation of this Warrant shall be determined in accordance
with the provisions of the Purchase Agreement.

 

Restrictions.
The Holder acknowledges that the Warrant Shares acquired upon the exercise of this Warrant, if not registered, and the Holder does
not utilize cashless exercise, will have restrictions upon resale imposed by state and federal securities laws.

 

No Net Cash Settlement.
The Holder acknowledges that, in the event that this Warrant is not exercisable for cash pursuant to Section 2 hereof, the
Warrant Shares may not be settled with the Company for the cash value or in assets or otherwise.

 

    	-15-

    	 

    

 

Nonwaiver and Expenses.
No course of dealing or any delay or failure to exercise any right hereunder on the part of Holder shall operate as a waiver of
such right or otherwise prejudice the Holder’s rights, powers or remedies. Without limiting any other provision of this Warrant
or the Purchase Agreement, if the Company willfully and knowingly fails to comply with any provision of this Warrant, which results
in any material damages to the Holder, the Company shall pay to the Holder such amounts as shall be sufficient to cover any costs
and expenses including, but not limited to, reasonable attorneys’ fees, including those of appellate proceedings, incurred
by the Holder in collecting any amounts due pursuant hereto or in otherwise enforcing any of its rights, powers or remedies hereunder.

 

Notices. Any
notice, request or other document required or permitted to be given or delivered to the Holder by the Company shall be delivered
in accordance with the notice provisions of the Purchase Agreement.

 

Limitation of Liability.
No provision hereof, in the absence of any affirmative action by the Holder to exercise this Warrant to purchase Warrant Shares,
and no enumeration herein of the rights or privileges of the Holder, shall give rise to any liability of the Holder for the purchase
price of any Common Stock or as a stockholder of the Company, whether such liability is asserted by the Company or by creditors
of the Company.

 

Remedies. The
Holder, in addition to being entitled to exercise all rights granted by law, including recovery of damages, will be entitled to
specific performance of its rights under this Warrant.  The Company agrees that monetary damages would not be adequate compensation
for any loss incurred by reason of a breach by it of the provisions of this Warrant and hereby agrees to waive and not to assert
the defense in any action for specific performance that a remedy at law would be adequate.

 

Successors and Assigns.
Subject to applicable securities laws, this Warrant and the rights and obligations evidenced hereby shall inure to the benefit
of and be binding upon the successors and permitted assigns of the Company and the successors and permitted assigns of Holder. 
The provisions of this Warrant are intended to be for the benefit of any Holder from time to time of this Warrant and shall be
enforceable by the Holder or holder of Warrant Shares.

 

Amendment. This
Warrant may be modified or amended or the provisions hereof waived with the written consent of the Company and the Holder.

 

Severability.
Wherever possible, each provision of this Warrant shall be interpreted in such manner as to be effective and valid under applicable
law, but if any provision of this Warrant shall be prohibited by or invalid under applicable law, such provision shall be ineffective
to the extent of such prohibition or invalidity, without invalidating the remainder of such provisions or the remaining provisions
of this Warrant.

 

Headings. The
headings used in this Warrant are for the convenience of reference only and shall not, for any purpose, be deemed a part of this
Warrant.
