A. The Bubble
Real Estate Company, LLC, a California limited liability company (“Landlord”), as Landlord, and Sublessor, as
Tenant, executed that certain lease dated March 29, 2012 (the “Master Lease”) for approximately 2,245
square feet of office space located in the Building at 8840 Wilshire Blvd., 3rd Floor, Beverly Hills, California 90211
(the “Premises”), a copy of which is attached hereto as Exhibit A and incorporated herein by this
reference.

 

B. By the terms

renewed.

 

C. Sublessor
previously entered into a month to month sublease for the Subleased Premises with Frank Litvack (“Litvack”),

NOW, THEREFORE,
the parties mutually agree as follows:

hereby subleases, demises and lets to Sublessee, and Sublessee hereby hires and takes from Sublessor, one office and one administrative
bay located in the Premises, as more particularly described on Exhibit B, attached hereto and incorporated herein (the "Subleased

upon which spaces in the new area shall subject to this Sublease and shall indicate such change on an amended Exhibit B.
In addition to the foregoing, Sublessee shall have the right, in conjunction with other tenants of the Building in which the Premises

2.          Conversion
Rights. This Note may be converted into Shares on the terms and conditions set forth in this Section 2.

 

(a)          Conversion
at Option of the Holder. On or after the Conversion Commencement Date, the Holder shall be entitled to convert all or any part
of the Principal (and the Interest Amount thereon) or any Interest accrued hereunder into fully paid and nonassessable Shares (the
“Conversion Shares”) in accordance with this Section 2 at the Conversion Rate (as defined in Section
2(b)). The Company shall not issue any fraction of a Share upon any conversion. If the issuance would result in the issuance
of a fraction of a Share, then the Company shall round such fraction of a Share up or down to the nearest whole share (with 0.5
rounded up). Notwithstanding anything herein to the contrary, the Company shall not issue to the Holder, and the Holder may not
acquire, a number of Shares upon conversion of this Note or otherwise issue any shares of Common Stock pursuant hereto or the Facility
Agreement to the extent that, upon such conversion, the number of Shares then beneficially owned by the Holder and its Affiliates
and any other persons or entities whose beneficial ownership of Common Stock would be aggregated with the Holder’s for purposes
of Section 13(d) of the Exchange Act (including shares held by any “group” of which the Holder is a member, but excluding
shares beneficially owned by virtue of the ownership of securities or rights to acquire securities that have limitations on the
right to convert, exercise or purchase similar to the limitation set forth herein) would exceed 9.985% of the total number of shares
of Common Stock then issued and outstanding (the “9.985% Cap”), provided, however, that the 9.985% Cap shall
only apply to the extent that the Common Stock is deemed to constitute an “equity security” pursuant to Rule 13d-1(i)
promulgated under the Exchange Act. For purposes hereof, “group” has the meaning set forth in Section 13(d) of the
Exchange Act and applicable regulations of the Securities and Exchange Commission (“SEC”), and the percentage
held by the Holder shall be determined in a manner consistent with the provisions of Section 13(d) of the Exchange Act. Upon the
written request of the Holder, the Company shall, within two (2) Trading Days, confirm orally and in writing to the Holder the
number of Shares then outstanding.

 

(b)          Conversion
Rate. The number of Conversion Shares issuable upon a conversion of any portion of this Note pursuant to Section 2 shall
be determined according to the following formula (the “Conversion Rate”):

_______Conversion Amount_______

 Conversion Price

 

(c)          Mechanics
of Conversion. The conversion of this Note shall be conducted in the following manner:

 

(i)          Holder’s
Delivery Requirements. To convert a Conversion Amount into Conversion Shares on any date (the “Conversion Date”),
the Holder shall (A) transmit by facsimile or electronic mail (or otherwise deliver), for receipt on or prior to 5:00 p.m.
New York City time on such date, a copy of an executed conversion notice in the form attached hereto as Exhibit A (the “Conversion
Notice”) to the Company (Attention: Steven A. Shallcross, 209 Perry Parkway, Suite 7, Gaithersburg, MD 20877,
Fax: (240) 299-2690, Email: [____________]), and (B) if required by Section 2(c)(vi), surrender to a common
carrier for delivery to the Company, no later than three (3) Business Days after the Conversion Date, the original Note being converted
(or an indemnification undertaking in customary form with respect to this Note in the case of its loss, theft or destruction).

 

    	6

    	 

    

 

(ii)         Company’s
Response. Upon receipt or deemed receipt by the Company of a copy of a Conversion Notice, the Company (I) shall immediately
send, via facsimile, a confirmation of receipt of such Conversion Notice to the Holder and the Company’s designated transfer
agent (the “Transfer Agent”), which confirmation shall constitute an instruction to the Transfer Agent to process
such Conversion Notice in accordance with the terms herein and (II) on or before the second (2nd) Business Day following
the date of receipt or deemed receipt by the Company of such Conversion Notice (the “Share Delivery Date”) (A)
provided that the Transfer Agent is participating in The Depository Trust Company (“DTC”) Fast Automated Securities
Transfer Program and provided that the Holder is eligible to receive Shares through DTC, credit such aggregate number of Conversion
Shares to which the Holder shall be entitled to the Holder’s or its designee’s balance account with DTC through its
Deposit Withdrawal Agent Commission system, or (B) if the foregoing shall not apply, issue and deliver to the address as specified
in the Conversion Notice, a stock certificate, registered in the name of the Holder or its designee, for the number of Conversion
Shares to which the Holder shall be entitled. If this Note is submitted for conversion, as may be required by Section 2(c)(vi),
and the Principal represented by this Note is greater than the Principal being converted, then the Company shall, as soon as practicable
and in no event later than three (3) Business Days after receipt of this Note (the “Note Delivery Date”) and
at its own expense, issue and deliver to the Holder a new Note representing the Principal not converted and cancel this Note. This
Note and the Conversion Shares will be free-trading, and freely transferable, and will not contain a legend restricting the resale
or transferability of the Conversion Shares if the Unrestricted Conditions (as defined below) are met.

 

(iii)        Dispute
Resolution. In the case of a dispute as to the determination of the Conversion Price or the arithmetic calculation of the Conversion
Rate, the Company shall instruct the Transfer Agent to issue to the Holder the number of Conversion Shares that is not disputed
and shall transmit an explanation of the disputed determinations or arithmetic calculations to the Holder via facsimile within
two (2) Business Days of receipt or deemed receipt of the Holder’s Conversion Notice or other date of determination. If the
Holder and the Company are unable to agree upon the determination of the Conversion Price or arithmetic calculation of the Conversion
Rate within one (1) Business Day of such disputed determination or arithmetic calculation being transmitted to the Holder, then
the Company shall promptly (and in any event within two (2) Business Days) submit via facsimile (A) the disputed determination
of the Conversion Price to an independent, reputable investment banking firm agreed to by the Company and the Required Note Holders,
or (B) the disputed arithmetic calculation of the Conversion Rate to the Company’s independent registered public accounting
firm, as the case may be. The Company shall direct the investment bank or the accounting firm, as the case may be, to perform the
determinations or calculations and notify the Company and the Holder of the results no later than two (2) Business Days from the
time it receives the disputed determinations or calculations. Such investment bank’s or accounting firm’s determination
or calculation, as the case may be, shall be binding upon all parties absent manifest error.

 

    	7

    	 

    

 

(iv)        Record
Holder. The person or persons entitled to receive the Conversion Shares issuable upon a conversion of this Note shall be treated
for all purposes as the legal and record holder or holders of such Shares upon delivery of the Conversion Notice via facsimile,
electronic mail or otherwise in accordance with the terms hereof.

 

(v)         Company’s
Failure to Timely Convert.

 

(A)         Cash
Damages. If within three (3) Business Days after the Company’s receipt of the facsimile or electronic mail copy of a
Conversion Notice or deemed receipt of a Conversion Notice the Company shall fail to issue and deliver a certificate to the Holder
for, or credit the Holder’s or its designee’s balance account with DTC with, the number of Conversion Shares (free
of any restrictive legend if the Unrestricted Conditions (as defined below) are met) to which the Holder is entitled upon the Holder’s
conversion of any Conversion Amount, or if the Company fails to issue and deliver a new Note representing the Principal to which
such Holder is entitled on or before the Note Delivery Date pursuant to Section 2(c)(ii), then in addition to all other
available remedies that the Holder may pursue hereunder and under the Facility Agreement, the Company shall pay additional damages
to the Holder for each day after the Share Delivery Date such conversion is not timely effected and/or each day after the Note
Delivery Date such Note is not delivered in an amount equal to one percent (1%) of the sum of the following: (a) in the event the
Company has failed to deliver the Conversion Shares to the Holder or its designee on or prior to the Share Delivery Date, the product
of (I) the number of Conversion Shares not issued to the Holder or its designee on or prior to the Share Delivery Date and to which
the Holder is entitled and (II) the Volume Weighted Average Price of the Common Stock on the Share Delivery Date (such product
is referred to herein as the “Share Product Amount”), and (b) in the event the Company has failed to deliver
a Note to the Holder on or prior to the Note Delivery Date, the product of (y) the number of Conversion Shares issuable upon conversion
of the Principal represented by the Note to have been delivered as of the Note Delivery Date and (z) the Volume Weighted Average
Price of the Common Stock on the Note Delivery Date. Alternatively, subject to Section 2(c)(iii), at the election of the
Holder made in the Holder’s sole discretion, the Company shall pay to the Holder, in lieu of the additional damages referred
to in the preceding sentence (but in addition to all other available remedies that the Holder may pursue hereunder and under the
Facility Agreement), 115% of the amount by which (A) the Holder’s total purchase price (including brokerage commissions,
if any) for the Shares purchased to make delivery in satisfaction of a sale by the Holder of the Conversion Shares to which the
Holder is entitled but has not received upon a conversion exceeds (B) the net proceeds received by the Holder from the sale of
the Shares to which the Holder is entitled but has not received upon such conversion. If the Company fails to pay the additional
damages set forth in this Section 2(c)(v)(A) within five (5) Business Days of the date incurred, then the Holder entitled
to such payments shall have the right at any time, so long as the Company continues to fail to make such payments, to require the
Company, upon written notice, to immediately issue, in lieu of such cash damages, the number of Shares equal to the quotient of
(X) the aggregate amount of the damages payments described herein divided by (Y) the Conversion Price in effect on such Conversion
Date as specified by the Holder in the Conversion Notice.

 

    	8

    	 

    

 

(B)         Void
Conversion Notice. If for any reason the Holder has not received all of the Conversion Shares prior to the tenth (10th) Business
Day after the Share Delivery Date with respect to a conversion of this Note (a “Conversion Failure”), then the
Holder, upon written notice to the Company (a “Void Conversion Notice”), may void its Conversion Notice with
respect to, and retain or have returned, as the case may be, any portion of this Note that has not been converted pursuant to the
Holder’s Conversion Notice; provided, that the voiding of the Holder’s Conversion Notice shall not affect the
Company’s obligations to make any payments that have accrued prior to the date of such notice pursuant to Section 2(c)(v)(A)
or otherwise.

 

(C)         Event
of Default. A Conversion Failure shall constitute an Event of Default under the Facility Agreement and entitle the Lenders
to all payments and remedies provided under the Facility Agreement upon the occurrence of an Event of Default.

 

(vi)        Book-Entry.
Notwithstanding anything to the contrary set forth herein, upon conversion or redemption of this Note in accordance with the terms
hereof, the Holder shall not be required to physically surrender this Note to the Company unless all of the Principal is being
converted or redeemed. The Holder and the Company shall maintain records showing the Principal converted or redeemed and the dates
of such conversions or redemptions or shall use such other method, reasonably satisfactory to the Holder and the Company, so as
not to require physical surrender of this Note upon any such partial conversion or redemption. Notwithstanding the foregoing, if
this Note is converted or redeemed as aforesaid, the Holder may not transfer this Note unless the Holder first physically surrenders
this Note to the Company, whereupon the Company will forthwith issue and deliver upon the order of the Holder a new Note of like
tenor, registered as the Holder may request, representing in the aggregate the remaining Principal represented by this Note. The
Holder and any assignee, by acceptance of this Note, acknowledge and agree that, by reason of the provisions of this paragraph,
following conversion or redemption of any portion of this Note, the Principal of this Note may be less than the principal amount
stated on the face hereof.

 

(d)          Taxes.
The Company shall pay any and all taxes (excluding income taxes, franchise taxes or other taxes levied on gross earnings, profits
or the like of the Holder) that may be payable with respect to the issuance and delivery of Conversion Shares upon the conversion
of this Note.

 

(e)          Legends.

 

(i)          Restrictive
Legend. The Holder understands that until such time as this Note or the Conversion Shares have been registered under the Securities
Act as contemplated by the Registration Rights Agreement or otherwise may be sold pursuant to Rule 144 under the Securities Act
or an exemption from registration under the Securities Act without any restriction as to the number of securities as of a particular
date that can then be immediately sold, this Note and the Conversion Shares, as applicable, may bear a restrictive legend in substantially
the following form (and a stop-transfer order may be placed against transfer of the certificates for such securities):

 

    	9

    	 

    

 

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE
HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS. THE SECURITIES MAY
NOT BE SOLD, TRANSFERRED, ASSIGNED, PLEDGED, HYPOTHECATED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF AN EFFECTIVE REGISTRATION
STATEMENT FOR THE SECURITIES UNDER SAID ACT, OR PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER SAID ACT INCLUDING, WITHOUT LIMITATION,
PURSUANT TO RULES 144 OR 144A UNDER SAID ACT OR PURSUANT TO A PRIVATE SALE EFFECTED UNDER APPLICABLE FORMAL OR INFORMAL SEC INTERPRETATION
OR GUIDANCE, SUCH AS A SO-CALLED “4(1) AND A HALF” SALE.”

 

“THE SALE, TRANSFER OR ASSIGNMENT OF THE SECURITIES
REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO THE TERMS AND CONDITIONS OF A CERTAIN REGISTRATION RIGHTS AGREEMENT DATED AS OF
MARCH __, 2014, AS AMENDED FROM TIME TO TIME, AMONG THE COMPANY AND CERTAIN HOLDERS OF ITS OUTSTANDING SECURITIES. COPIES OF SUCH
AGREEMENT MAY BE OBTAINED AT NO COST BY WRITTEN REQUEST MADE BY THE HOLDER OF RECORD OF THIS CERTIFICATE TO THE SECRETARY OF THE
COMPANY.”

 

(ii)         Removal
of Restrictive Legends. This Note and the certificates evidencing the Conversion Shares, as applicable, shall not contain any
legend restricting the transfer thereof (including the legend set forth above in subsection 2(e)(i)): (A) while a registration
statement (including a Registration Statement, as defined in the Registration Rights Agreement) covering the sale or resale of
such security is effective under the Securities Act, or (B) following any sale of such Note and/or Conversion Shares pursuant to
Rule 144, or (C) if such Note or Conversion Shares, as the case may be, are eligible for sale under Rule 144(b)(1), or (D) if such
legend is not required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements
issued by the staff of the SEC) (collectively, the “Unrestricted Conditions”). The Company shall cause its counsel
to issue a legal opinion to the Transfer Agent promptly after the Effective Date (as defined below), or at such other time as the
Unrestricted Conditions have been satisfied, if required by the Company’s transfer agent to effect the issuance of this Note
or the Conversion Shares, as applicable, without a restrictive legend or removal of the legend hereunder. If the Unrestricted Conditions
are met at the time of issuance of the Conversion Shares, then the Conversion Shares shall be issued free of all legends. The Company
agrees that following the Effective Date or at such time as the Unrestricted Conditions are met or such legend is otherwise no
longer required under this Section 2(e), it will, no later than three (3) Trading Days following the delivery (the “Unlegended
Shares Delivery Deadline”) by the Holder to the Company or the Transfer Agent of this Note and a certificate representing
Conversion Shares, as applicable, issued with a restrictive legend (such third Trading Day, the “Legend Removal Date”),
deliver or cause to be delivered to such Holder this Note and/or a certificate (or electronic transfer) representing such shares
that is free from all restrictive and other legends. For purposes hereof, “Effective Date” shall mean the date
that the Registration Statement that the Company is required to file pursuant to the Registration Rights Agreement has been declared
effective by the SEC.

 

    	10

    	 

    

 

(iii)        Sale
of Unlegended Shares. Holder agrees that the removal of the restrictive legend from this Note and any certificates representing
securities as set forth in Section 2(e) above is predicated upon the Company’s reliance that the Holder will sell
this Note or any Conversion Shares, as applicable, pursuant to either the registration requirements of the Securities Act, including
any applicable prospectus delivery requirements, or an exemption therefrom, and that if such securities are sold pursuant to a
Registration Statement, they will be sold in compliance with the plan of distribution set forth therein.

 

3.          Rights
Upon Major Transaction. In the event that a Major Transaction occurs, then the Holder, at its option, may require the Company
to redeem the Principal Amount outstanding on the Holder’s Notes in accordance with Section 3(b) below. In the event
the Holder shall not have exercised any of its rights under the immediately preceding sentence above within the applicable time
periods set forth herein, then the Major Transaction shall be treated as an Assumption (as defined below) in accordance with Section
3(a) below unless the Holder waives its rights under this Section 3 with respect to such Major Transaction.

 

(a)          Assumption.
In addition to any other rights provided to the Holder hereunder, under the Facility Agreement or otherwise, prior to the consummation
of any Major Transaction that is to be treated as an Assumption pursuant to this Section 3, the Company will secure from
the Person purchasing the Company’s assets or Common Stock, or any successor entity resulting from such Major Transaction
(in each case, the “Successor Entity”) a written agreement, in form and substance reasonably satisfactory to
the Required Note Holders and approved by the Required Note Holders (which approval shall not be unreasonably withheld), to deliver
to the Holder in exchange for this Note, a security of the Successor Entity evidenced by a written instrument substantially similar
in form and substance to this Note and reasonably satisfactory to the Required Note Holders and approved by the Required Note Holders
(which approval shall not be unreasonably withheld), which instrument shall have a principal amount and interest rate equal to
the Principal and the interest rate of the Note, have similar ranking and have similar conversion rights, provided that
such new instrument shall ensure (in a manner reasonably satisfactory to the Required Note Holders) that the Holder will thereafter
have the right to acquire and receive, in lieu of or in addition to (as the case may be) the Shares immediately theretofore acquirable
and receivable upon the conversion of this Note (without regard to any limitations or restrictions on conversion), such shares
of stock, securities or assets of the Successor Entity that would have been issued or payable in such Major Transaction with respect
to or in exchange for the number of Shares that would have been acquirable and receivable upon the conversion of this Note as of
the date of such Major Transaction (without taking into account any limitations or restrictions on the conversion of this Note).
Prior to the consummation of any other Major Transaction, the Company shall make appropriate provision (in form and substance reasonably
satisfactory to the Required Note Holders and approved by the Required Note Holders (which approval shall not be unreasonably withheld))
to ensure that the Holder will thereafter have the right to acquire and receive, in lieu of or in addition to (as the case may
be) the Shares immediately theretofore acquirable and receivable upon the conversion of this Note (without regard to any limitations
or restrictions on conversion), such shares of stock, securities or assets that would have been issued or payable in such Major
Transaction with respect to or in exchange for the number of Shares that would have been acquirable and receivable upon the conversion
of this Note as of the date of such Major Transaction (without taking into account any limitations or restrictions on the conversion
of this Note). Any assumption of Company obligations under this paragraph shall be referred to herein as an “Assumption.”

 

    	11

    	 

    

 

(b)          Notice;
Major Transaction Early Termination Right. At least thirty (30) days prior to the consummation of any Major Transaction, but,
in any event, within five (5) Business Days following the first to occur of (x) the date of the public announcement of such Major
Transaction if such announcement is made before 4:00 p.m., New York City time, or (y) the day following the public announcement
of such Major Transaction if such announcement is made on and after 4:00 p.m., New York City time, the Company shall deliver written
notice thereof via facsimile and overnight courier to the Holder (a “Major Transaction Notice”). At any time
during the period beginning after the Holder’s receipt of a Major Transaction Notice and ending five (5) Trading Days prior
to the consummation of such Major Transaction (the “Early Termination Period”), the Holder may require the Company
to redeem (an “Early Termination Upon Major Transaction”) all or any portion of this Note (without taking into
consideration the 9.985% Cap or whether the Conversion Commencement Date has occurred) by delivering written notice thereof (“Major
Transaction Early Termination Notice”) to the Company, which Major Transaction Early Termination Notice shall indicate
the portion of the Note (the “Early Termination Amount”), calculated with reference to the number of Shares
into which such portion is convertible relative to the total number of shares into which the Note is convertible, that the Holder
is electing to have redeemed. The portion of this Note subject to early termination pursuant to this Section 3(b) (the “Redeemable
Shares”), shall be redeemed by the Company at a price (the “Major Transaction Note Early Termination Price”)
payable in cash equal to the “Black Scholes Value” of the Redeemable Shares determined by use of the Black Scholes
Option Pricing Model using the criteria set forth in Schedule 1 hereto (the “Black Scholes Value”).

 

(c)          Escrow;
Payment of Major Transaction Note Early Termination Price. Following the receipt of a Major Transaction Early Termination Notice
from the Holder, the Company shall not effect a Major Transaction that is being treated as an early termination unless either (i)
it obtains the written agreement of the Successor Entity that payment of the Major Transaction Note Early Termination Price shall
be made to the Holder prior to consummation of such Major Transaction and such payment shall be a condition precedent to consummation
of such Major Transaction or (ii) it shall first place into an escrow account with an independent escrow agent, at least three
(3) business days prior to the closing date of the Major Transaction (the “Major Transaction Escrow Deadline”),
an amount in cash, equal to the Major Transaction Note Early Termination Price. Concurrently upon closing of such Major Transaction,
the Company shall pay or shall instruct the escrow agent to pay the Major Transaction Note Early Termination Price. For purposes
of determining the amount required to be placed in escrow pursuant to the provisions of this subsection (c) and without affecting
the amount of the actual Major Transaction Note Early Termination Price, the calculation of the price referred to in clause (1)
of the first column of Schedule 1 hereto with respect to Stock Price shall be determined based on the Closing Market Price (as
defined on Schedule 1) of the Common Stock on the Trading Day immediately preceding the date that the funds are deposited with
the escrow agent.

 

    	12

    	 

    

 

(d)          Injunction.
Following the receipt of a Major Transaction Early Termination Notice from the Holder, in the event that the Company attempts to
consummate a Major Transaction without either (i) placing the Major Transaction Note Early Termination Price in escrow in accordance
with subsection (c) above, (ii) payment of the Major Transaction Note Early Termination Price to the Holder prior to consummation
of such Major Transaction or (iii) obtaining the written agreement of the Successor Entity described in subsection (c) above, the
Holder shall have the right to apply for an injunction in any state or federal courts sitting in the City of New York, borough
of Manhattan to prevent the closing of such Major Transaction until the Major Transaction Note Early Termination Price is paid
to the Holder, in full.

 

An early termination
required by this Section 3 shall have priority to payments to holders of Common Stock in connection with a Major Transaction,
and to the extent an early termination required by this Section 3 is deemed or determined by a court of competent jurisdiction
to be prepayments of the Note by the Company, such early termination shall be deemed to be voluntary prepayments. Notwithstanding
anything to the contrary in this Section 3, until the Major Transaction Note Early Termination Price is paid in full, this
Note may be converted, in whole or in part, by the Holder into Shares, or in the event the Conversion Date is after the consummation
of the Major Transaction, shares of publicly traded common stock (or their equivalent) of the Successor Entity pursuant to this
Section 3. The parties hereto agree that in the event of the early termination of any portion of the Note under this Section
3, the Holder’s damages would be uncertain and difficult to estimate because of the parties’ inability to predict
future interest rates and the uncertainty of the availability of a suitable substitute investment opportunity for the Holder. Accordingly,
any premium due under this Section 3 is intended by the parties to be, and shall be deemed, a reasonable estimate of the
Holder’s actual loss of its investment opportunity and not as a penalty.

 

4.          Registration
Failures. Upon any Registration Failure, in addition to all other available remedies that the Holder may pursue hereunder and
under the Facility Agreement, the Registration Rights Agreement and the Warrants, the Company shall pay additional damages to the
Holder for each 30-day period (prorated for any partial period) after the date of such Registration Failure in an amount in cash
equal to two percent (2%) of such Holder’s original principal amount of this Note on the date of such Registration Failure.
Such payments shall accrue until the earlier of (i) such time as the Registration Failure has been cured and (ii) the date on which
all of the Conversion Shares may be sold without restriction under Rule 144 (including, without limitation, volume restrictions
and without the need for the availability of current public information under Rule 144). All such payments that accrue under this
Section (4) shall be payable no later than five business days following such date of accrual.

 

5.          Voting
Rights. Except as required by law, the Holder shall have no voting rights with respect to any of the Conversion Shares until
the Conversion Date relating to the conversion of this Note upon which such Conversion Shares are issuable (or in the case of Conversion
Shares the issuance of which is subject to a bona fide dispute that is subject to and being resolved pursuant to, and in
compliance with the time periods and other provisions of, the dispute resolution provisions of Section 2(c)(iii), the first
Business Day after the resolution of such bona fide dispute).

 

    	13

    	 

    

 

6.          Amendment;
Waiver. The terms and provisions of this Note shall not be amended or waived except in a writing signed by the Company and
the Holder.

 

7.          Remedies,
Characterizations, Other Obligations, Breaches and Injunctive Relief. The remedies provided in this Note shall be cumulative
and in addition to all other remedies available under this Note, the Facility Agreement, at law or in equity (including a decree
of specific performance and/or other injunctive relief). No remedy contained herein shall be deemed a waiver of compliance with
the provisions giving rise to such remedy, and nothing herein shall limit the Holder’s right to pursue actual damages for
any failure by the Company to comply with the terms of this Note. The Company covenants to the Holder that there shall be no characterization
concerning this instrument other than as expressly provided herein. Amounts set forth or provided for herein with respect to payments,
conversion and the like (and the computation thereof) shall be the amounts to be received by the Holder thereof and shall not,
except as expressly provided herein, be subject to any other obligation of the Company (or the performance thereof). The Company
acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the Holder and that the remedy at
law for any such breach may be inadequate. The Company therefore agrees that, in the event of any such breach or threatened breach,
the Holder shall be entitled, in addition to all other available remedies, to an injunction restraining any breach, without the
necessity of showing economic loss and without any bond or other security being required.

 

8.          Specific
Shall Not Limit General; Construction. No specific provision contained in this Note shall limit or modify any more general
provision contained herein. This Note shall be deemed to be jointly drafted by the Company and all purchasers of Notes pursuant
to the Facility Agreement and shall not be construed against any Person as the drafter hereof.

 

9.          Failure
or Indulgence Not Waiver. No failure or delay on the part of the Holder in the exercise of any power, right or privilege hereunder
shall operate as a waiver thereof, nor shall any single or partial exercise of any such power, right or privilege preclude other
or further exercise thereof or of any other right, power or privilege.

 

10.         Notices.
Whenever notice is required to be given under this Note, unless otherwise provided herein, such notice shall be given in accordance
with Section 6.1 of the Facility Agreement.

 

11.         Restrictions
on Transfer.

 

(a)          Registration
or Exemption Required. This Note has been issued in a transaction exempt from the registration requirements of the Securities
Act by virtue of Regulation D. None of the Note or the Conversion Shares may be pledged, transferred, sold, assigned, hypothecated
or otherwise disposed of except pursuant to an effective registration statement or an exemption to the registration requirements
of the Securities Act and applicable state laws including, without limitation, a so-called “4(1) and a half” transaction.

 

    	14

    	 

    

 

(b)          Assignment.
Subject to Section 11(a), the Holder may sell, transfer, assign, pledge, hypothecate or otherwise dispose of this Note,
in whole or in part. Holder shall deliver a written notice to Company, substantially in the form of the Assignment attached hereto
as Exhibit B, indicating the Person or Persons to whom the Note shall be assigned and the respective principal amount of
the Note to be assigned to each assignee. The Company shall effect the assignment within three (3) business days (the “Transfer
Delivery Period”), and shall deliver to the assignee(s) designated by Holder a Note or Notes of like tenor and terms
for the appropriate principal amount. This Note and the rights evidenced hereby shall inure to the benefit of and be binding upon
the successors and assigns of the Holder. The provisions of this Note are intended to be for the benefit of all Holders from time
to time of this Note, and shall be enforceable by any such Holder. For avoidance of doubt, in the event Holder notifies the Company
that such sale or transfer is a so called “4(1) and half” transaction, the parties hereto agree that a legal opinion
from outside counsel for the Holder delivered to counsel for the Company substantially in the form attached hereto as Exhibit
C shall be the only requirement to satisfy an exemption from registration under the Securities Act to effectuate such “4(1)
and half” transaction.

 

12.         Payment
of Collection, Enforcement and Other Costs. If (a) this Note is placed in the hands of an attorney for collection or enforcement
or is collected or enforced through any legal proceeding; or (b) an attorney is retained to represent the Holder in any bankruptcy,
reorganization, receivership of the Company or other proceedings affecting Company creditors’ rights and involving a claim
under this Note, then the Company shall pay the costs incurred by the Holder for such collection, enforcement or action, including
reasonable attorneys’ fees and disbursements.

 

13.         Cancellation.
After all Principal, Interest and other amounts at any time owed under, or on account of, this Note have been paid in full or converted
into Shares in accordance with the terms hereof, this Note shall automatically be deemed cancelled, shall be surrendered to the
Company for cancellation and shall not be reissued.

 

14.         Registered
Note. In order to qualify as a “registered note” for purposes of the Code, transfer of this Note may be effected
only by (i) surrender of this Note to the Company and the re-issuance of this Note to the transferee, or the Company’s issuance
to the Holder of a new note in the same form as this Note but with the transferee denoted as the Holder, or (ii) the recording
of the identity of the transferee by the Affiliate of the Holder that is maintaining a record ownership register of this Note as
a non-fiduciary agent of, and on behalf of, the Company for the tax purposes set forth herein. Such Affiliate in its capacity as
such agent shall notify the Company in writing immediately upon any change in such identity. Any attempted transfer in violation
of the relevant provisions of this Note shall be void and of no force and effect. Until there has been a valid transfer of this
Note and of all of the rights hereunder by the Holder in accordance with this Note, the Company shall deem and treat the Holder
as the absolute beneficial owner and holder of this Note and of all of the rights hereunder for all purposes (including, without
limitation, for the purpose of receiving all payments to be made under this Note).

 

    	15

    	 

    

 

15.         Waiver
of Notice. To the extent permitted by law, the Company hereby waives demand, notice, presentment, protest and all other demands
and notices in connection with the delivery, acceptance, performance, default or enforcement of this Note and the Facility Agreement.

 

16.         Governing
Law. This Note shall be construed and enforced in accordance with, and all questions concerning the construction, validity,
interpretation and performance of this Note and all disputes arising hereunder shall be governed by, the laws of the State of New
York, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of New York or any
other jurisdictions) that would cause the application of the laws of any jurisdictions other than the State of New York. The Company
(a) agrees that any legal action or proceeding with respect to this Note or any other agreement, document, or other instrument
executed in connection herewith, shall be brought exclusively in any state or federal court located within New York, New York,
(b) irrevocably waives any objections which the Company may now or hereafter have to the venue of any suit, action or proceeding
arising out of or relating to this Note, or any other agreement, document, or other instrument executed in connection herewith,
brought in the aforementioned courts, (c) further irrevocably waives any claim that any such suit, action, or proceeding brought
in any such court has been brought in an inconvenient forum and (d) hereby consents that personal service of summons or other legal
process may be made as set forth in Section 5.4 of the Facility Agreement. EACH OF THE COMPANY AND THE HOLDER (BY ACCEPTANCE HEREOF)
IRREVOCABLY WAIVES THE RIGHT TO A TRIAL BY JURY IN ANY ACTION OR PROCEEDING BROUGHT TO ENFORCE ANY PROVISION OF THIS NOTE OR ANY
OTHER TRANSACTION DOCUMENT.
