	Issuance Date: October 19, 2010	 	Original Principal Amount: U.S. $[                ]

FOR VALUE RECEIVED, Biovest International, Inc., a Delaware corporation (the “Company”), and debtor in
possession, hereby promises to pay to [BUYER] or registered assigns (the “Holder”) the amount set out above as the Original Principal Amount (as reduced pursuant to the terms hereof pursuant to redemption, conversion or otherwise,
the “Principal”) when due, whether upon the Maturity Date (as defined below), acceleration, redemption, conversion or otherwise (in each case in accordance with the terms hereof) and to pay interest (“Interest”) on
any outstanding Principal at the Interest Rate from the date identified above as the Issuance Date (the “Issuance Date”) until the same becomes due and payable, whether upon an Interest Date (as defined below), the Maturity Date,
acceleration, conversion, redemption or otherwise (in each case in accordance with the terms hereof). This Debtor in Possession Secured Convertible Note (including all Debtor in Possession Secured Convertible Notes issued in exchange, transfer or
replacement hereof, this “Note”) is one of an issue of Debtor in Possession Secured Convertible Notes (collectively, the “Notes” and such other Debtor in Possession Secured Convertible Notes, the “Other
Notes”) issued on the Closing Date pursuant to the Securities Purchase Agreement (as defined below). Certain capitalized terms used herein are defined in Section 30. 

  
 (1) PAYMENTS OF
PRINCIPAL. On the Maturity Date, the Company shall pay to the Holder an amount in cash representing all outstanding Principal and accrued and unpaid Interest. The “Maturity Date” shall be December 15, 2010, as may be
extended at the option of the Holder (i) in the event that, and for so long as, an Event of Default (as defined in Section 4(a)) shall have occurred and be continuing on the Maturity Date (as may be extended pursuant to this
Section 1) or any event shall have occurred and be continuing on the Maturity Date (as may be extended pursuant to this Section 1) that with the passage of time and the failure to cure would result in an Event of Default and
(ii) through the date that is ten (10) Business Days after the consummation of a Change of Control in the event that a Change of Control is publicly announced or a Change of Control Notice (as defined in Section 5(b)) is delivered
prior to the Maturity Date. Other than as specifically permitted by this Note, the Company may not prepay any portion of the outstanding Principal and accrued and unpaid Interest. 

(2) INTEREST; INTEREST RATE. (a) Interest on this Note shall commence accruing on the Issuance Date and shall be computed on
the basis of a 360-day year and twelve 30-day months and shall be payable in arrears on the first calendar day of each succeeding month after the Issuance Date (each, an “Interest Date”) with the first Interest Date being
December 1, 2010. Interest shall be payable on each Interest Date, to the record holder of this Note on the applicable Interest Date, in shares of Common Stock (“Interest Shares”) so long as there has been no Equity Conditions
Failure; provided however, that the Company may, at its option following notice to the Holder, pay Interest on any Interest Date in cash (“Cash Interest”) or in a combination of Cash Interest and Interest Shares. The Company shall
deliver a written notice to each holder of the Notes on or prior to the twenty-fifth (25th) Trading Day prior to the applicable Interest Date (the date such notice is delivered to all of the holders of Notes, the “Interest Notice
Date”) which notice (i) either (A) confirms that Interest to be paid on such Interest Date shall be paid entirely in Interest Shares or (B) elects to pay Interest as Cash Interest or a combination of Cash Interest and
Interest Shares and specifies the amount of Interest that shall be paid as Cash Interest and the amount of Interest, if any, that shall be paid in Interest Shares and (ii) certifies that the Equity Conditions are satisfied as of such Interest
Notice Date; provided that the Company must simultaneously take the same action in the same proportion with respect to the Other Notes. If the Equity Conditions are not satisfied as of the Interest Notice Date, then unless the Company has elected to
pay such Interest as Cash Interest, the Interest Notice shall indicate that unless the Holder waives the Equity Conditions, the Interest shall be paid as Cash Interest. If the Equity Conditions were satisfied as of the Interest Notice Date but the
Equity Conditions are no longer satisfied at any time prior to the Interest Date, the Company shall provide the Holder a subsequent notice to that effect indicating that unless the Holder waives the Equity Conditions, the Interest shall be paid as
Cash Interest. Interest to be paid on an Interest Date in Interest Shares shall be paid in a number of fully paid and nonassessable shares (rounded up to the nearest whole share in accordance with Section 3(a)) of Common Stock equal to the
quotient of (1) the amount of Interest payable on such Interest Date less any Cash Interest paid on such Interest Date and (2) the Interest Conversion Price in effect on the applicable Interest Date. 

(b) When any Interest Shares are to be paid on an Interest Date, the Company shall (i) (A) provided that the Company’s
transfer agent (the “Transfer Agent”) is participating in the Depository Trust Company (“DTC”) Fast Automated Securities Transfer Program, credit such aggregate number of Interest 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 

  
 - 2 -

 
Commission system, or (B) if the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program, issue and deliver on the applicable Interest Date, to the address
set forth in the register maintained by the Company for such purpose pursuant to the Securities Purchase Agreement or to such address as specified by the Holder in writing to the Company at least two (2) Business Days prior to the applicable
Interest Date, a certificate, registered in the name of the Holder or its designee, for the number of Interest Shares to which the Holder shall be entitled and (ii) with respect to each Interest Date, pay to the Holder, in cash by wire transfer
of immediately available funds, the amount of any Cash Interest. 
 (c) From and after the occurrence and during the
continuance of an Event of Default, the Interest Rate shall be increased to fifteen percent (15.0%) per annum. In the event that such Event of Default is subsequently cured, the adjustment referred to in the preceding sentence shall cease to be
effective as of the date of such cure; provided that the Interest as calculated and unpaid at such increased rate during the continuance of such Event of Default shall continue to apply to the extent relating to the days after the occurrence of such
Event of Default through and including the date of cure of such Event of Default. The Company shall pay any and all transfer, stamp, and similar taxes that may be payable with respect to the issuance and delivery of Interest Shares. 

(3) CONVERSION OF NOTES. This Note shall be convertible into shares of the Company’s common stock, par value $0.01 per share
(the “Common Stock”), on the terms and conditions set forth in this Section 3. 
 (a) Conversion
Right. Subject to the provisions of Section 3(d), at any time or times on or after the date hereof, the Holder shall be entitled to convert any portion of the outstanding and unpaid Conversion Amount (as defined below) into fully paid and
nonassessable shares of Common Stock in accordance with Section 3(c), at the Conversion Rate (as defined below). The Company shall not issue any fraction of a share of Common Stock upon any conversion. If the issuance would result in the
issuance of a fraction of a share of Common Stock, the Company shall round such fraction of a share of Common Stock up to the nearest whole share. The Company shall pay any and all transfer, stamp and similar taxes that may be payable with respect
to the issuance and delivery of Common Stock upon conversion of any Conversion Amount. 
 (b) Conversion Rate. The
number of shares of Common Stock issuable upon conversion of any Conversion Amount pursuant to Section 3(a) shall be determined by dividing (x) such Conversion Amount by (y) the Conversion Price (the “Conversion
Rate”). 
 (i) “Conversion Amount” means the sum of (A) the portion of the
Principal to be converted, redeemed or otherwise with respect to which this determination is being made, and (B) accrued and unpaid Interest with respect to such Principal. 

(ii) “Conversion Price” means, as of any Conversion Date (as defined below) or other date of
determination, $0.91, subject to adjustment as provided herein.

 (c) Mechanics of
Conversion. 
 (i) Optional Conversion. To convert any Conversion Amount into shares of Common Stock
on any date (a “Conversion Date”), the Holder shall (A) transmit by facsimile (or otherwise deliver), for receipt on or prior to 11:59 p.m., New York time, on such date, a copy of an executed notice of conversion in the form
attached hereto as Exhibit I (the “Conversion Notice”) to the Company and the Transfer Agent and (B) if required by Section 3(c)(iv), surrender this Note to a common carrier for delivery to the Company as soon as
practicable on or following such date (or an indemnification undertaking with respect to this Note in the case of its loss, theft or destruction). On or before the first (1st) Business Day following the date of receipt of a Conversion Notice,
the Company shall transmit by facsimile a confirmation of receipt of such Conversion Notice to the Holder and the Transfer Agent. On or before the third (3rd) Trading Day following the date of receipt of a Conversion Notice (the “Share
Delivery Date”), the Company shall (x) provided that the Transfer Agent is participating in the DTC Fast Automated Securities Transfer Program, credit such aggregate number of shares of Common Stock 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 (y) if the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program, issue
and deliver to the address as specified in the Conversion Notice, a certificate, registered in the name of the Holder or its designee, for the number of shares of Common Stock to which the Holder shall be entitled. If this Note is physically
surrendered for conversion as required by Section 3(c)(iv) and the outstanding Principal of this Note is greater than the Principal portion of the Conversion Amount being converted, then the Company shall, as soon as practicable and in no event
later than five (5) Business Days after receipt of this Note and at its own expense, issue and deliver to the holder a new Note (in accordance with Section 17(d)) representing the outstanding Principal not converted. The Person or Persons
entitled to receive the shares of Common Stock issuable upon a conversion of this Note shall be treated for all purposes as the record holder or holders of such shares of Common Stock on the Conversion Date. 

(ii) Make-Whole Amount Upon Conversion. In addition to the foregoing, on each Share Delivery Date, any applicable
Make-Whole Amount on such Conversion Amount (the “Make-Whole Conversion Amount”) shall be paid to the Holder in shares of Common Stock (“Make-Whole Shares”) so long as there has been no Equity Conditions Failure;
provided however, that the Company may, at its option following notice to the Holder, pay such Make-Whole Conversion Amount in cash (“Make-Whole Cash”) or in a combination of Make-Whole Shares and Make-Whole Cash. In the event that
the Company desires to elect to pay any portion of its Make-Whole Conversion Amount as a Make-Whole Cash, then the Company shall deliver a written notice (“Make-Whole Notice”) to the Holder no later than one (1) Trading Day
following the receipt of the Conversion Notice by the Company (the “Make-Whole Notice Date”), which notice elects to pay the Make-Whole Conversion Amount in the form of a Make-Whole Cash or a combination of a Make-Whole Cash and
Make-Whole Shares and specifies the amount of the Make-Whole Conversion Amount that shall be paid as a Make-Whole Cash and the amount of Make-Whole Conversion Amount, if any, that shall be paid in Make-Whole Shares. If the Equity Conditions are not
satisfied as of the 

  
 - 4 -

 
Conversion Date, then unless the Company has elected to pay such Make-Whole Conversion Amount as a Make-Whole Cash, the Make-Whole Notice shall indicate that unless the Holder waives the Equity
Conditions, the Make-Whole Conversion Amount shall be paid in the form of a Make-Whole Cash. If the Equity Conditions were satisfied as of the Conversion Date but the Equity Conditions are no longer satisfied at any time prior to the Share Delivery
Date, the Company shall provide the Holder a subsequent notice to that effect indicating that unless the Holder waives the Equity Conditions, the Make-Whole Conversion Amount shall be paid in the form of a Make-Whole Cash. The Make-Whole Conversion
Amount to be paid on such Share Delivery Date in Make-Whole Shares shall be paid in a number of fully paid and nonassessable shares of Common Stock (rounded to the nearest whole share in accordance with Section 3(a)) equal to the quotient of
(1) the Make-Whole Conversion Amount payable on the applicable Conversion Date less any Make-Whole Cash paid and (2) the Interest Conversion Price in effect on the applicable Conversion Date. Delivery of the Make-Whole Shares shall be made
in the manner set forth in Section 2(b)(i) of this Note replacing the terms “Interest Shares” with “Make-Whole Shares” and “Interest Date” with “Share Delivery Date.” 

(iii) Company’s Failure to Timely Convert. If the Company shall fail to issue a certificate to the Holder or
credit the Holder’s balance account with DTC, as applicable, for the number of shares of Common Stock to which the Holder is entitled upon conversion of any Conversion Amount on or prior to the date which is three (3) Trading Days after
the Conversion Date (a “Conversion Failure”), then (A) the Company shall pay damages to the Holder for each Trading Day of such Conversion Failure in an amount equal to 1.5% of the product of (1) the sum of the number of
shares of Common Stock not issued to the Holder on or prior to the Share Delivery Date and to which the Holder is entitled, and (2) the Closing Sale Price of the Common Stock on the Share Delivery Date and (B) the Holder, upon written
notice to the Company, 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 such Conversion Notice; provided that the voiding of a
Conversion Notice shall not affect the Company’s obligations to make any payments which have accrued prior to the date of such notice pursuant to this Section 3(c)(iii) or otherwise. In addition to the foregoing, if within three
(3) Trading Days after the Company’s receipt of the facsimile copy of a Conversion Notice, the Company shall fail to issue and deliver a certificate to the Holder or credit the Holder’s balance account with DTC for the number of
shares of Common Stock to which the Holder is entitled upon such holder’s conversion of any Conversion Amount, and if on or after such Trading Day the Holder purchases (in an open market transaction or otherwise) Common Stock to deliver in
satisfaction of a sale by the Holder of Common Stock issuable upon such conversion that the Holder anticipated receiving from the Company (a “Buy-In”), then the Company shall, within five (5) Trading Days after the
Holder’s request and in the Holder’s discretion, either (i) pay cash to the Holder in an amount equal to the Holder’s total purchase price (including brokerage commissions and other out-of-pocket expenses, if any) for the shares
of Common Stock so purchased (the “Buy-In Price”), at which point the Company’s obligation to deliver such certificate (and to issue such Common Stock) shall terminate, or (ii) promptly honor its obligation to deliver to
the Holder a certificate or certificates representing such Common Stock and pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In Price over the product of (A) such number of shares of Common Stock, times (B) the
Closing Bid Price on the Conversion Date.

 (iv)
Registration; Book-Entry. The Company shall maintain a register (the “Register”) for the recordation of the names and addresses of the holders of each Note and the principal amount of the Notes held by such holders (the
“Registered Notes”). The entries in the Register shall be conclusive and binding for all purposes absent manifest error. The Company and the holders of the Notes shall treat each Person whose name is recorded in the Register as the
owner of a Note for all purposes, including, without limitation, the right to receive payments of Principal and Interest, if any, hereunder, notwithstanding notice to the contrary. A Registered Note may be assigned or sold in whole or in part only
by registration of such assignment or sale on the Register. Upon its receipt of a request to assign or sell all or part of any Registered Note by a Holder, the Company shall record the information contained therein in the Register and issue one or
more new Registered Notes in the same aggregate principal amount as the principal amount of the surrendered Registered Note to the designated assignee or transferee pursuant to Section 17. Notwithstanding anything to the contrary in this
Section 3(c)(iv), a Holder may assign any Note or any portion thereof to an Affiliate of such Holder or a Related Fund of such Holder without delivering a request to assign or sell such Note to the Company and the recordation of such assignment
or sale in the Register (a “Related Party Assignment”); provided, that (x) the Company may continue to deal solely with such assigning or selling Holder unless and until such Holder has delivered a request to assign or
sell such Note or portion thereof to the Company for recordation in the Register; (y) the failure of such assigning or selling Holder to deliver a request to assign or sell such Note or portion thereof to the Company shall not affect the
legality, validity, or binding effect of such assignment or sale; and (z) such assigning or selling Holder shall, acting solely for this purpose as a non-fiduciary agent of the Company, maintain a register (the “Related Party
Register”) comparable to the Register on behalf of the Company, and any such assignment or sale shall be effective upon recordation of such assignment or sale in the Related Party Register. Notwithstanding anything to the contrary set forth
herein, upon conversion of any portion of this Note in accordance with the terms hereof, the Holder shall not be required to physically surrender this Note to the Company unless (A) the full Conversion Amount represented by this Note is being
converted or (B) the Holder has provided the Company with prior written notice (which notice may be included in a Conversion Notice) requesting physical surrender and reissue of this Note. The Holder and the Company shall maintain records
showing the Principal and Interest converted and the dates of such conversions 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 conversion. 

(v) Pro Rata Conversion; Disputes. In the event that the Company receives a Conversion Notice from more than one
holder of Notes for the same Conversion Date and the Company can convert some, but not all, of such portions of the Notes submitted for conversion, the Company, subject to Section 3(d), shall convert from each holder of Notes electing to have
Notes converted on such date a pro rata amount of such holder’s portion of its Notes submitted for conversion based on the principal amount of Notes submitted for conversion on such date by such holder relative to the aggregate

  
 - 6 -

 
principal amount of all Notes submitted for conversion on such date. In the event of a dispute as to the number of shares of Common Stock issuable to the Holder in connection with a conversion of
this Note, the Company shall issue to the Holder the number of shares of Common Stock not in dispute and resolve such dispute in accordance with Section 22. 

(d) Limitations on Conversions; Beneficial Ownership. The Company shall not effect any conversion of this
Note, and the Holder of this Note shall not have the right to convert any portion of this Note pursuant to Section 3(a), to the extent that after giving effect to such conversion, the Holder (together with the Holder’s Affiliates) would
beneficially own in excess of 4.99% (the “Maximum Percentage”) of the number of shares of Common Stock outstanding immediately after giving effect to such conversion. 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 conversion of this Note with respect to which the determination of such sentence is being made, but shall exclude the
number of shares of Common Stock which would be issuable upon (A) conversion of the remaining, nonconverted portion of this Note beneficially owned by the Holder or any of its Affiliates and (B) exercise or conversion of the unexercised or
nonconverted portion of any other securities of the Company (including, without limitation, any Other Notes or warrants) 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 3(d), beneficial ownership shall be calculated in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended (the
“Exchange Act”). For purposes of this Section 3(d), in determining the number of outstanding shares of Common Stock, the Holder may rely on the number of outstanding shares of Common Stock as reflected in (x) the
Company’s most recent Form 10-K, Form 10-Q or Form 8-K, as the case may be, (y) a more recent public announcement by the Company or (z) any other notice by the Company or the Transfer Agent setting forth the number of shares of Common
Stock outstanding. For any reason at any time, upon the written or oral request of the Holder, the Company shall within one (1) Business Day 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 Note, by the Holder or its Affiliates since the date as of which such
number of outstanding shares of Common Stock was reported. By written notice to the Company, the Holder may increase or decrease the Maximum Percentage to any other percentage not in excess of 9.99% specified in such notice; provided that
(i) any such increase will not be effective until the sixty-first (61st) day after such notice is delivered to the Company, and (ii) any such increase or decrease will apply only to the Holder and not to any other holder of Notes. The provisions of this paragraph
shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 3(d) 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.

proceeds of such insurance or indemnity within thirty (30) days of the issuance of such judgment; provided that no payments made on account of allowed claims pursuant to the terms of the Company’s Plan of Reorganization and confirmation
order entered by the Bankruptcy Court relating to the Company’s Chapter 11 Case shall constitute an Event of Default;

Section 12. To the extent redemptions required by this Section 4(b) are deemed or determined by a court of competent jurisdiction to be prepayments of the Note by the Company, such redemptions shall be deemed to be voluntary prepayments.
The parties hereto agree that in the event of the Company’s redemption of any portion of the Note under this Section 4(b), 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 Event of Default redemption premium due under this Section 4(b) 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. 
 (5) RIGHTS UPON FUNDAMENTAL TRANSACTION AND CHANGE OF CONTROL. 
 (a)
Assumption. The Company shall not enter into or be party to a Fundamental Transaction unless (i) the Successor Entity assumes in writing all of the obligations of the Company under this Note and the other Transaction Documents in
accordance with the provisions of this Section 5(a) pursuant to written agreements in form and substance reasonably satisfactory to the Required Holders and approved by the Required Holders prior to such

  
 - 11 -

 
Fundamental Transaction, including agreements to deliver to each holder of Notes in exchange for such Notes a security of the Successor Entity evidenced by a written instrument substantially
similar in form and substance to the Notes, including, without limitation, having a principal amount and interest rate equal to the principal amounts and the interest rates of the Notes then outstanding held by such holder, having similar conversion
rights and having similar ranking and security to the Notes, and satisfactory to the Required Holders and (ii) the Successor Entity (including its Parent Entity) is a publicly traded corporation whose common stock is quoted on or listed for
trading on an Eligible Market. Upon the occurrence of any Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Fundamental Transaction, the provisions of this Note referring
to the “Company” shall refer instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations of the Company under this Note with the same effect as if such Successor Entity
had been named as the Company herein. Upon consummation of the Fundamental Transaction, the Successor Entity shall deliver to the Holder confirmation that there shall be issued upon conversion or redemption of this Note at any time after the
consummation of the Fundamental Transaction, in lieu of the shares of the Company’s Common Stock (or other securities, cash, assets or other property) issuable upon the conversion or redemption of the Notes prior to such Fundamental
Transaction, such shares of the publicly traded common stock (or their equivalent) of the Successor Entity (including its Parent Entity), as adjusted in accordance with the provisions of this Note. The provisions of this Section shall apply
similarly and equally to successive Fundamental Transactions and shall be applied without regard to any limitations on the conversion or redemption of this Note. 
 (b) Redemption Right. No sooner than fifteen (15) days nor later than ten (10) days prior to the consummation of a Change of Control, but not prior to the public announcement of such
Change of Control, the Company shall deliver written notice thereof via facsimile and overnight courier to the Holder (a “Change of Control Notice”). At any time during the period beginning after the Holder’s receipt of a
Change of Control Notice and ending twenty (20) Trading Days after the date of the consummation of such Change of Control, the Holder may require the Company to redeem (a “Change of Control Redemption”) all or any portion of
this Note by delivering written notice thereof (“Change of Control Redemption Notice”, and the date thereof, the “Change of Control Redemption Notice Date”) to the Company, which Change of Control Redemption Notice
shall indicate the Conversion Amount the Holder is electing to require the Company to redeem. The portion of this Note subject to redemption pursuant to this Section 5(b) shall be redeemed by the Company in cash at a price equal to 110% of the
sum of (i) any Make-Whole Amount and (ii) the greater of (x) the Conversion Amount to be redeemed and (y) the product of (A) the Conversion Rate in effect at such time as the Holder delivers a Change of Control Redemption
Notice with respect to such Conversion Amount being redeemed and (B) the greatest Weighted Average Price of the Common Stock during the period beginning on the date immediately preceding the earlier to occur of (1) the consummation of the
Change of Control and (2) the public announcement of such Change of Control and ending on the date the Holder delivers the Change of Control Redemption Notice (the “Change of Control Redemption Price”). Redemptions required by
this Section 5 shall be made in accordance with the provisions of Section 12 and shall have priority to payments to stockholders in connection with a Change of Control. To the extent redemptions required by this Section 5(b) are
deemed or determined by a court of competent jurisdiction to be prepayments of the Note by the Company, such redemptions shall be deemed to be voluntary prepayments. Notwithstanding anything to the contrary in this Section 5,

  
 - 12 -

 
but subject to Section 3(d), until the Change of Control Redemption Price (together with any interest thereon) is paid in full, the Conversion Amount submitted for redemption under this
Section 5(b) (together with any interest thereon) may be converted, in whole or in part, by the Holder into Common Stock pursuant to Section 3. The parties hereto agree that in the event of the Company’s redemption of any portion of
the Note under this Section 5(b), 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 Change of Control redemption premium due under this Section 5(b) 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. 
 (6) DISTRIBUTION OF ASSETS; RIGHTS UPON ISSUANCE OF PURCHASE RIGHTS AND OTHER
CORPORATE EVENTS. 
 (a) Distribution of Assets. If the Company shall declare or make any dividend or other
distributions of its assets (or rights to acquire its assets) to any or all 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) (the “Distributions”), the Company shall make appropriate provision to insure that upon a
conversion of this Note, the Holder will thereafter have the right to receive in addition to the shares of Common Stock receivable upon such conversion, such Distributions to which the Holder would have been entitled with respect to such shares of
Common Stock had such shares of Common Stock been held by the Holder immediately prior to the date on which a record is taken for such Distribution or, if no such record is taken, the date as of which the record holders of Common Stock are to be
determined for such Distributions (without taking into account any limitations or restrictions on the convertibility of this Note). 
 (b) Purchase Rights. If at any time the Company grants, issues or sells any Options, Convertible Securities or rights to purchase stock, warrants, securities or other property pro rata to the
record holders of any class 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 conversion of this Note (without taking into account any limitations or restrictions on the convertibility of this Note) immediately prior to 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.

 (c) Other Corporate Events. In addition to and not in substitution for any other rights hereunder, prior to the
consummation of any Fundamental Transaction pursuant to which holders of shares of Common Stock are entitled to receive securities or other assets with respect to or in exchange for shares of Common Stock (a “Corporate Event”), the
Company shall make appropriate provision to insure that the Holder will thereafter have the right to receive upon a conversion of this Note, (i) in addition to the shares of Common Stock receivable upon such conversion, such securities or other
assets to which the Holder would have been entitled with respect to such shares of Common Stock had such shares of Common Stock been held by the 

  
 - 13 -

 
Holder upon the consummation of such Corporate Event (without taking into account any limitations or restrictions on the convertibility of this Note) or (ii) in lieu of the shares of Common
Stock otherwise receivable upon such conversion, such securities or other assets received by the holders of shares of Common Stock in connection with the consummation of such Corporate Event in such amounts as the Holder would have been entitled to
receive had this Note initially been issued with conversion rights for the form of such consideration (as opposed to shares of Common Stock) at a conversion rate for such consideration commensurate with the Conversion Rate. Provision made pursuant
to the preceding sentence shall be in a form and substance satisfactory to the Required Holders. The provisions of this Section shall apply similarly and equally to successive Corporate Events and shall be applied without regard to any limitations
on the conversion or redemption of this Note. 
 (7) RIGHTS UPON ISSUANCE OF OTHER SECURITIES. 

(a) Adjustment of Conversion Price upon Issuance of Common Stock. If and whenever on or after the Subscription Date, the Company
issues or sells, or in accordance with this Section 7(a) is deemed to have issued or sold, any shares of Common Stock (excluding Excluded Securities and shares of Common Stock deemed to have been issued or sold by the Company in connection with
any Excluded Securities) for a consideration per share (the “New Issuance Price”) less than a price (the “Applicable Price”) equal to the Conversion Price in effect immediately prior to such issue or sale or deemed
issuance (the foregoing a “Dilutive Issuance”), then immediately after such Dilutive Issuance the Conversion Price then in effect shall be reduced concurrently with such Dilutive Issuance to (A) in the event that the Dilutive
Issuance is completed at a time during which at least one-third of the Original Principal Amount of the Notes remains outstanding (the “Ratchet Period”), to the New Issuance Price, and (B) in the event that the Dilutive
Issuance is completed at a time that less than one-third of the Original Principal Amount of the Notes remain outstanding, an amount determined by multiplying the Conversion Price then in effect by a fraction, (x) the numerator of which shall
be the sum of (1) the number of shares of Common Stock Deemed Outstanding immediately prior to such Dilutive Issuance plus (2) the number of shares of Common Stock which the aggregate consideration received by the Company for such
additional shares in the Dilutive Issuance would purchase at the Conversion Price then in effect; and (y) the denominator of which shall be the number of shares of Common Stock Deemed Outstanding immediately after such Dilutive Issuance but
before giving effect to anti-dilution rights contained in other securities of the Company that would be triggered by the same Dilutive Issuance. For purposes of this paragraph, “Common Stock Deemed Outstanding” shall mean at any
given time, the number of shares of Common Stock outstanding at such time, plus the number of shares of Common Stock deemed to be outstanding pursuant to Sections 7(a)(i) and 7(a)(ii) hereof regardless of whether the Options or Convertible
Securities are actually exercisable at such time, but excluding any Common Stock owned or held by or for the account of the Company or issuable upon conversion or exercise, as applicable, of the Notes and the Warrants. For purposes of determining
the adjusted Conversion Price under this Section 7(a), the following shall be applicable: 
 (i)
Issuance of Options. If the Company in any manner grants any Options 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 issuable upon exercise of any such Option is less than the 

  
 - 14 -

 
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 7(a)(i), 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 Conversion 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. 

(ii) 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 7(a)(ii), 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 Conversion Price 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 the Conversion Price has been or is to be made pursuant to other provisions of this Section 7(a),
no further adjustment of the Conversion Price shall be made by reason of such issue or sale. 
 (iii) Change
in Option Price or Rate of Conversion. If the purchase price provided for in any Options issued after the Subscription Date, the additional consideration, if any, payable upon the issue, conversion, exercise or exchange of any Convertible
Securities issued after the Subscription Date, or the rate at which any Convertible Securities issued after the Subscription Date are convertible into or exercisable or exchangeable for shares of Common Stock increases or decreases at any time, the
Conversion Price at the time of such increase or decrease shall be adjusted to the Conversion 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 

  
 - 15 -

 
consideration or increased or decreased conversion rate, as the case may be, at the time initially granted, issued or sold. Additionally, if the terms of any Option or Convertible Security that
was outstanding as of the Subscription Date is 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, but in such event the amount of the adjustment to the Conversion Price pursuant to this Section 7 will not be proportionately greater than the
proportionate amount of the increase or decrease. No adjustment pursuant to this Section 7(a) shall be made if such adjustment would result in an increase of the Conversion Price then in effect. 

(iv) 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 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 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. 

  
 - 16 -

  
 (vi)
Variable-Priced Securities. If the Company issues or sells, or in accordance with Section 7 is deemed to have issued or sold, any Options or Convertible Securities after the Issuance Date, that are convertible into or exchangeable or
exercisable for shares of Common Stock at a price which varies or may vary with the market price of the shares of Common Stock, including by way of one or more reset(s) to a fixed price (each of the formulations for such variable price being herein
referred to as, a “Variable Price Formulation”), the Company shall provide written notice thereof via facsimile and overnight courier to the Holder (the “Variable Notice”) on the date of issuance or deemed issuance
of such Convertible Securities or Options. From and after the date the Company issues or is deemed to have issued any such Convertible Securities or Options with a Variable Price Formulation, but only for so long as such Convertible Securities or
Options are outstanding, the Holder shall have the right, but not the obligation, in its sole discretion to substitute any applicable Variable Price Formulation for the Conversion Price upon the Conversion of this Note by designating in the
Conversion Notice delivered upon any conversion of this Notes that solely for purposes of such conversion the Holder is relying on the Variable Price Formulation rather than the Conversion Price then in effect. The Holder’s election to rely on
a Variable Price Formulation for a particular conversion of this Note shall not obligate the Holder to rely on a Variable Price Formulation for any future conversion of this Note. In connection with determining the “lowest price per share for
which one share of Common Stock is issuable upon exercise of any Option” pursuant to Section 7(a)(i) and the “lowest price per share for which one share of Common Stock is issuable upon the conversion, exercise or exchange of a
Convertible Security” pursuant to Section 7(a)(ii), as such terms pertain solely to any Variable Price Formulation contained in any Option or Convertible Securities issued after the Issuance Date, such lowest price shall equal the lesser
of (i) the fixed exercise, conversion or exchange price set forth in the applicable Option or Convertible Security and (ii) the Variable Price Formulation contained in the applicable Option or Convertible Security, calculated as if such
Option or Convertible Security were converted, exercised or exchanged as of the date of issuance of the applicable Option or Convertible Security. 
 (b) Adjustment of Conversion Price upon Subdivision or Combination of Common Stock. If the Company at any time on or after the Subscription Date subdivides (by any stock split, stock dividend,
recapitalization or otherwise) one or more classes of its outstanding shares of Common Stock into a greater number of shares, the Conversion Price in effect immediately prior to such subdivision will be proportionately reduced. If the Company at any
time on or after the Subscription Date combines (by combination, reverse stock split or otherwise) one or more classes of its outstanding shares of Common Stock into a smaller number of shares, the Conversion Price in effect immediately prior to
such combination will be proportionately increased. 
 (c) De Minimis Adjustments. No adjustment in the Conversion Price
shall be required unless such adjustment would require an increase or decrease of at least $0.01 in such price; provided, however, that any adjustment which by reason of this Section 7(c) is not required to be made shall be carried forward and
taken into account in any subsequent adjustments 

  
 - 17 -

 
under this Section 7. All calculations under this Section 7 shall be made by the Company in good faith and shall be made to the nearest cent or to the nearest one hundredth of a share,
as applicable. No adjustment need be made for a change in the par value or no par value of the Company’s Common Stock. 

(d) Voluntary Adjustment By Company. The Company may at any time during the term of this Note reduce the then current Conversion
Price to any amount and for any period of time deemed appropriate by the Board of Directors of the Company. 
 (8)
NONCIRCUMVENTION. The Company hereby covenants and agrees that the Company will not, by amendment of its Certificate of Incorporation, Bylaws or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement,
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 Note, and will at all times in good faith carry out all of the provisions of this Note and take
all action as may be required to protect the rights of the Holder of this Note. 
 (9) RESERVATION OF AUTHORIZED SHARES.

 (a) Reservation. The Company shall initially reserve out of its authorized and unissued Common Stock a number of
shares of Common Stock for each of the Notes equal to 130% of the Conversion Rate with respect to the Conversion Amount of each such Note as of the Issuance Date. So long as any of the Notes are outstanding, the Company shall take all action
necessary to reserve and keep available out of its authorized and unissued Common Stock, solely for the purpose of effecting the conversion of the Notes, 130% of the number of shares of Common Stock as shall from time to time be necessary to effect
the conversion of all of the Notes then outstanding; provided that at no time shall the number of shares of Common Stock so reserved be less than the number of shares required to be reserved by the previous sentence (without regard to any
limitations on conversions) (the “Required Reserve Amount”). The initial number of shares of Common Stock reserved for conversions of the Notes and each increase in the number of shares so reserved shall be allocated pro rata among
the holders of the Notes based on the principal amount of the Notes held by each holder at the Closing (as defined in the Securities Purchase Agreement) or increase in the number of reserved shares, as the case may be (the “Authorized Share
Allocation”). In the event that a holder shall sell or otherwise transfer any of such holder’s Notes, each transferee shall be allocated a pro rata portion of such holder’s Authorized Share Allocation. Any shares of Common Stock
reserved and allocated to any Person which ceases to hold any Notes shall be allocated to the remaining holders of Notes, pro rata based on the principal amount of the Notes then held by such holders. 

(b) Insufficient Authorized Shares. If at any time while any of the Notes remain outstanding the Company does not have a
sufficient number of authorized and unreserved shares of Common Stock to satisfy its obligation to reserve for issuance upon conversion of the Notes at least a number of shares of Common Stock equal to the Required Reserve Amount (an
“Authorized Share Failure”), then the Company shall immediately take all action necessary to increase the Company’s authorized shares of Common Stock to an amount sufficient to allow the Company to reserve the Required Reserve
Amount for the Notes then outstanding. Without limiting the generality of the foregoing sentence, as soon as practicable after 

  
 - 18 -

 
the date of the occurrence of an Authorized Share Failure, but in no event later than sixty (60) days after the occurrence of such Authorized Share Failure, the Company shall either
(x) obtain the written consent of its stockholders for the approval of an increase in the number of authorized shares of Common Stock and provide each stockholder with an information statement with respect thereto or (y) hold a meeting of
its stockholders for the approval of an increase in the number of authorized shares of Common Stock. In connection with such meeting, the Company shall provide each stockholder with a proxy statement and shall use its best efforts to solicit its
stockholders’ approval of such increase in authorized shares of Common Stock and to cause its board of directors to recommend to the stockholders that they approve such proposal. 

(10) COMPANY’S RIGHT OF MANDATORY CONVERSION. 
 (a) Mandatory Conversion. At any time after the effective date (the “Effective Date”) of the Company’s Plan of Reorganization with respect to the Company’s Chapter 11
Case (the “Mandatory Conversion Eligibility Date”), if (i) the Weighted Average Price of the Common Stock listed on the Principal Market equals or exceeds 150% of the Conversion Price as of the Issuance Date (subject to
appropriate adjustments for stock splits, stock dividends, stock combinations and other similar transactions after the Issuance Date) for a period of ten (10) consecutive Trading Days commencing after the Mandatory Conversion Eligibility Date
(the “Mandatory Conversion Measuring Period”), and (ii) no Equity Conditions Failure has occurred, the Company shall have the right to require the Holder to convert all or any portion of the Conversion Amount then remaining
under this Note, in each case as designated in the Mandatory Conversion Notice (as defined below) into fully paid, validly issued and nonassessable shares of Common Stock in accordance with Section 3(c) hereof at the Conversion Rate as of the
Mandatory Conversion Date (as defined below) (a “Mandatory Conversion”). The Company may exercise its right to require conversion under this Section 10(a) by delivering within not more than two (2) Trading Days following
the end of such Mandatory Conversion Measuring Period a written notice thereof by facsimile and overnight courier to all, but not less than all, of the holders of Notes and the Transfer Agent (the “Mandatory Conversion Notice” and
the date all of the holders of the Notes received such notice by facsimile is referred to as the “Mandatory Conversion Notice Date”). The Mandatory Conversion Notice shall be irrevocable. The Mandatory Conversion Notice shall
(y) state (I) the Trading Day selected for the Mandatory Conversion, which Trading Day shall be no sooner than twenty (20) Trading Days nor later than sixty (60) Trading Days following the Mandatory Conversion Notice Date (the
“Mandatory Conversion Date”), (II) the aggregate Conversion Amount of the Notes subject to Mandatory Conversion from the Holder and all of the holders of the Notes pursuant to this Section 10(a) (and analogous provisions under
the Other Notes), (III) the number of shares of Common Stock to be issued to the Holder on the Mandatory Conversion Date and (z) certify that there has been no Equity Conditions Failure; provided, however, that the Company may not effect a
Mandatory Conversion under this Section in excess of the Holder Pro Rata Amount of the applicable Mandatory Conversion Volume Limitation. Notwithstanding the foregoing, the Company may not effect a Mandatory Conversion until a minimum of thirty
(30) consecutive days have elapsed after any prior Mandatory Conversion Date. 
 (b) Pro Rata Conversion
Requirement. If the Company elects to cause a conversion of any Conversion Amount of this Note pursuant to Section 10(a), then it must simultaneously take the same action in the same proportion with respect to the Other Notes. If the

  
 - 19 -

 
Company elects a Mandatory Conversion of this Note pursuant to Section 10(a) (or similar provisions under the Other Notes) with respect to less than all of the Conversion Amounts of the
Notes then outstanding, then the Company shall require conversion of a Conversion Amount from each of the holders of the Notes equal to the product of (1) the aggregate Conversion Amount of Notes which the Company has elected to cause to be
converted pursuant to Section 10(a), multiplied by (2) a fraction, the numerator of which is the sum of the aggregate Original Principal Amount of the Notes purchased by such holder of outstanding Notes and the denominator of which is the
sum of the aggregate Original Principal Amount of the Notes purchased by all holders holding outstanding Notes (such fraction with respect to each holder is referred to as its “Conversion Allocation Percentage,” and such amount with
respect to each holder is referred to as its “Pro Rata Conversion Amount”); provided, however, that in the event that any holder’s Pro Rata Conversion Amount exceeds the outstanding Principal amount of such holder’s Note,
then such excess Pro Rata Conversion Amount shall be allocated amongst the remaining holders of Notes in accordance with the foregoing formula. In the event that the initial holder of any Notes shall sell or otherwise transfer any of such
holder’s Notes, the transferee shall be allocated a pro rata portion of such holder’s Conversion Allocation Percentage and the Pro Rata Conversion Amount. 
 (11) OPTIONAL REDEMPTION AT THE COMPANY’S ELECTION. 
 (a)
General. At any time after the date hereof, so long as there has been no Equity Conditions Failure, the Company shall have the right to redeem all or any portion of the Conversion Amount then remaining under this Note (the “Company
Optional Redemption Amount”) as designated in the Company Optional Redemption Notice on the Company Optional Redemption Date (each as defined below) (a “Company Optional Redemption”). The portion of this Note subject to
redemption pursuant to this Section 11(a) shall be redeemed by the Company in cash at a price equal to 110% of the sum of (x) any Make-Whole Amount and (y) the Conversion Amount being redeemed (the “Company Optional Redemption
Price”). The Company may exercise its right to require redemption under this Section 11 by delivering a written notice thereof by facsimile and overnight courier to all, but not less than all, of the holders of Notes (the
“Company Optional Redemption Notice” and the date all of the holders received such notice is referred to as the “Company Optional Redemption Notice Date”). Each Company Optional Redemption Notice shall be
irrevocable. The Company Optional Redemption Notice shall state (1) the date on which the Company Optional Redemption shall occur (the “Company Optional Redemption Date”), which date shall not be less than thirty
(30) Business Days nor more than sixty (60) Business Days following the Company Optional Redemption Notice Date, and (2) the aggregate Conversion Amount of the Notes which the Company has elected to be subject to Company Optional
Redemption from the Holder and all of the other holders of the Notes pursuant to this Section 11(a) (and analogous provisions under the Other Notes) on the Company Optional Redemption Date. The Company may not effect a Company Optional
Redemption until a minimum of five (5) consecutive Trading Days have elapsed after any prior Company Optional Redemption Date. Notwithstanding anything to the contrary in this Section 11, until the Company Optional Redemption Price is paid
in full, the Company Optional Redemption Amount may be converted, in whole or in part, by the Holders into shares of Common Stock pursuant to Section 3. If the Holder so elects, any or all of the Conversion Amounts converted by the Holder after
the Company Optional Redemption Notice Date shall reduce the Company Optional Redemption Amount of this Note required to be redeemed on the Company Optional Redemption Date. Redemptions made pursuant to this Section 11 shall be made in
accordance with Section 12. 

  
 - 20 -

  
 (b) Pro Rata
Redemption Requirement. If the Company elects to cause a Company Optional Redemption pursuant to Section 11(a), then it must simultaneously take the same action in the same proportion with respect to the Other Notes. If the Company elects
to cause a Company Optional Redemption pursuant to Section 11(a) (or similar provisions under the Other Notes) with respect to less than all of the Conversion Amounts of the Notes then outstanding, then the Company shall require redemption of a
Conversion Amount from each of the holders of the Notes equal to the product of (i) the aggregate Conversion Amount of Notes which the Company has elected to cause to be redeemed pursuant to Section 11(a), multiplied by (ii) a
fraction, the numerator of which is the sum of the aggregate Original Principal Amount of the Notes purchased by such holder of outstanding Notes and the denominator of which is the sum of the aggregate Original Principal Amount of the Notes
purchased by all holders holding outstanding Notes (such fraction with respect to each holder is referred to as its “Company Redemption Allocation Percentage”, and such amount with respect to each holder is referred to as its
“Pro Rata Company Redemption Amount”); provided, however that in the event that any holder’s Pro Rata Company Redemption Amount exceeds the outstanding Principal amount of such holder’s Note, then such excess Pro Rata
Company Redemption Amount shall be allocated amongst the remaining holders of Notes in accordance with the foregoing formula. In the event that the initial holder of any Notes shall sell or otherwise transfer any of such holder’s Notes, the
transferee shall be allocated a pro rata portion of such holder’s Company Redemption Allocation Percentage and Pro Rata Company Redemption Amount. 
 (12) REDEMPTIONS. 
 (a) Mechanics. The Company shall deliver the
applicable Event of Default Redemption Price to the Holder within five (5) Business Days after the Company’s receipt of the Holder’s Event of Default Redemption Notice (the “Event of Default Redemption Date”). If the
Holder has submitted a Change of Control Redemption Notice in accordance with Section 5(b), the Company shall deliver the applicable Change of Control Redemption Price to the Holder (i) concurrently with the consummation of such Change of

New Notes. Whenever the Company is required to issue a new Note pursuant to the terms of this Note, such new Note (i) shall be of like tenor with this Note, (ii) shall represent, as indicated on the face of such new Note, the Principal
remaining outstanding (or in the case of a new Note being issued pursuant to Section 17(a) or Section 17(c), the Principal designated by the Holder which, when added to the principal represented by the other new Notes issued in connection

Issuance Date of this Note, (iv) shall have the same rights and conditions as this Note, and (v) shall represent accrued and unpaid Interest of this Note, from the Issuance Date. 

(18) 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 and any of the other Transaction Documents at law or in equity (including a decree of specific performance and/or other injunctive relief), and nothing herein shall limit the
Holder’s right to pursue actual and consequential damages for any failure by the Company to comply with the terms of this Note. 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 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,

reorganization, receivership of the Company or other proceedings affecting Company creditors’ rights and involving a claim under this Note (other than the Company’s Chapter 11 Case), then the Company shall pay the costs incurred by the
Holder for such collection, enforcement or action or in connection with such bankruptcy, reorganization, receivership or other proceeding, including, but not limited to, attorneys’ fees and disbursements.

(21) 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 unless a waiver signed by the Holder is set forth in writing, 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 except as otherwise set forth in a written instrument signed by Holder.

the case may be, to the Holder. If the Holder and the Company are unable to agree upon such determination or calculation within one (1) Business Day of such disputed determination or arithmetic calculation being submitted to the Holder, then
the Company shall, within one Business Day submit via facsimile (a) the disputed determination of the Closing Bid Price, the Closing Sale Price or the Weighted Average Price to an independent, reputable investment bank selected by the Holder

notify the Company and the Holder of the results no later than five (5) Business Days from the time it receives the disputed determinations or calculations. Such investment bank’s or accountant’s determination or calculation, as the
case may be, shall be binding upon all parties absent demonstrable error.

may elect to receive a payment of cash via wire transfer of immediately available funds by providing the Company with prior written notice setting out such request and the Holder’s wire transfer instructions. Whenever any amount expressed to be
due by the terms of this Note is due on any 

  
 - 26 -

 
day which is not a Business Day, the same shall instead be due on the next succeeding day which is a Business Day and, in the case of any Interest Date which is not the date on which this Note is
paid in full, the extension of the due date thereof shall not be taken into account for purposes of determining the amount of Interest due on such date. 
 (24) CANCELLATION. After all Principal, accrued Interest and other amounts at any time owed on this Note have been paid in full, this Note shall automatically be deemed canceled, shall be
surrendered to the Company for cancellation and shall not be reissued.

by law, the Company hereby waives demand, notice, protest and all other demands and notices in connection with the delivery, acceptance, performance, default or enforcement of this Note and the Securities Purchase Agreement.

successor trustee or estate representative, or any other creditor or party in interest in the Chapter 11 Case or any successor case; provided, however, that the foregoing provision shall (i) be limited solely to a Superpriority Claim
against only the Collateral and not against any other assets of the Company and (ii) not create any priority or seniority to any claims of Laurus Master Fund Ltd. (In Liquidation) and its Affiliates, Corps Real, LLC or Accentia
Biopharmaceuticals, Inc. in any and all assets of the Company (excluding the Collateral). No cost or expense of administration in the Company’s Chapter 11 Case under any provision of the Bankruptcy Code, including, but not limited to, sections
105, 326, 328, 330, 331, 363, 364, 503, 506, 507, 546, 726, 1113 or 1114 or any other provision of the Bankruptcy Code or otherwise (whether incurred in the Company’s Chapter 11 Case or any successor case under any chapter of the Bankruptcy
Code), shall be senior to, equal to, or pari passu with, the allowed Superpriority Claims granted the holders of the Notes hereunder; provided, however, that the foregoing provision shall (i) be limited solely to a Superpriority
Claim against only the Collateral and not against any other assets of the Company and (ii) not create any priority or seniority to any claims of Laurus Master Fund Ltd. (In Liquidation) and its Affiliates, Corps Real, LLC or Accentia
Biopharmaceuticals, Inc. in any and all assets of the Company (excluding the Collateral). The allowed Superpriority Claim granted the Holder and the holder of the Other Notes hereunder against only the Collateral and not against any other assets of
the Company shall continue in the Company’s Chapter 11 Case and in any successor case under any chapter of the Bankruptcy Code, and shall maintain their priority until all of the aggregate outstanding Principal and unpaid and accrued Interest
owing under the Notes has been indefeasibly paid in full and the Notes have been cancelled. 

  
 - 27 -

  
 (27) EXCHANGE OF
NOTES. On the Effective Date, this Note shall be mandatorily exchanged for the Exchange Note attached to the Securities Purchase Agreement in the form attached thereto as Exhibit A-2 (the “Exchange Note”). On the
Effective Date, the Holder shall deliver this Note to the Company and concurrently with such delivery, the Company shall issue the Exchange Note to the Holder and cancel this Note.  

(28) GOVERNING LAW; JURISDICTION; JURY TRIAL. For the period from the entry of the Approval Order until the Effective Date, all
disputes under this Note and any other Transaction Document shall be subject to the exclusive jurisdiction of the Bankruptcy Court. This Note shall be construed and enforced in accordance with, and all questions concerning the construction,
validity, interpretation and performance of this Note shall be governed by, the internal 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. After the Effective Date, except as provided in Section 22, the Company hereby irrevocably submits to the exclusive jurisdiction
of the state and federal courts sitting in The City of New York, Borough of Manhattan, for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably
waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is brought in an inconvenient forum or that the venue of such
suit, action or proceeding is improper. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law. Nothing contained herein shall be deemed or operate to preclude the Holder from bringing
suit or taking other legal action against the Company in any other jurisdiction to collect on the Company’s obligations to the Holder, to realize on any collateral or any other security for such obligations, or to enforce a judgment or other
court ruling in favor of the Holder. THE COMPANY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION WITH OR ARISING OUT OF THIS NOTE OR ANY
TRANSACTION CONTEMPLATED HEREBY. 
 (29) SEVERABILITY. If any provision of this Note is prohibited by law or
otherwise determined to be invalid or unenforceable by a court of competent jurisdiction, the provision that would otherwise be prohibited, invalid or unenforceable shall be deemed amended to apply to the broadest extent that it would be valid and
enforceable, and the invalidity or unenforceability of such provision shall not affect the validity of the remaining provisions of this Note so long as this Note as so modified continues to express, without material change, the original intentions
of the parties as to the subject matter hereof and the prohibited nature, invalidity or unenforceability of the provision(s) in question does not substantially impair the respective expectations or reciprocal obligations of the parties or the
practical realization of the benefits that would otherwise be conferred upon the parties. The parties will endeavor in good faith negotiations to replace the prohibited, invalid or unenforceable provision(s) with a valid provision(s), the effect of
which comes as close as possible to that of the prohibited, invalid or unenforceable provision(s). If it shall be found that any default interest or other amount deemed interest due hereunder violates the applicable law governing usury, the
applicable rate of interest due hereunder shall automatically be lowered to equal the maximum rate of interest permitted under applicable law. The Company covenants (to the extent that it may lawfully do so) that it shall

  
 - 28 -

 
not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law or other law which would prohibit or forgive the
Company from paying all or any portion of the principal of or default interest on this Note as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this indenture, and
the Company (to the extent it may lawfully do so) hereby expressly waives all benefits or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the
Holder, but will suffer and permit the execution of every such as though no such law has been enacted.

 Number of Shares of Common Stock:                      

Date of Issuance: October 19, 2010 (“Issuance Date”) 

Biovest International, Inc., a company organized under the laws of Delaware (the “Company”), hereby
certifies that, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, [BUYER], the registered holder hereof or its permitted assigns (the “Holder”), is entitled, subject to the terms set
forth below, to purchase from the Company, at the Exercise Price (as defined below) then in effect, upon surrender of this Warrant to Purchase Common Stock (including any Warrants to Purchase Common Stock issued in exchange, transfer or replacement
hereof, the “Warrant”), at any time or times on or after the Effective Date (as defined in the Securities Purchase Agreement) (the “Initial Exercisability Date”), but not after 11:59 p.m., New York time, on the
Expiration Date (as defined below),                     
(                    )1 fully paid nonassessable shares of Common Stock, par value $0.01 per share, subject to adjustment as provided herein
(the “Warrant Shares”). Except as otherwise defined herein, capitalized terms in this Warrant shall have the meanings set forth in Section 16. This Warrant is one of the Series A Warrants to purchase Common Stock (the
“SPA Warrants”) issued pursuant to Section 1 of that certain Securities Purchase Agreement, dated as of October 19, 2010 (the “Subscription Date”), by and among the Company and the investors (the
“Buyers”) referred to therein (the “Securities Purchase Agreement”). 
  

	1	 Insert number of shares equal to such holder’s pro rata share of the aggregate principal amount of SPA Securities sold by the Company pursuant to
the Securities Purchase Agreement divided by $0.91. 

 1. EXERCISE OF WARRANT. 

(a) Mechanics of Exercise. Subject to the terms and conditions hereof (including, without limitation, the
limitations set forth in Section 1(f)), this Warrant may be exercised by the Holder on any time or times on or after the Initial Exercisability Date, in whole or in part, by (i) delivery of a written notice, in the form attached hereto as
Exhibit A (the “Exercise Notice”), of the Holder’s election to exercise this Warrant and (ii) (A) payment to the Company of an amount equal to the applicable Exercise Price multiplied by the number of Warrant Shares
as to which this Warrant is being exercised (the “Aggregate Exercise Price”) in cash or by wire transfer of immediately available funds or (B) by notifying the Company that this Warrant is being exercised pursuant to a Cashless
Exercise (as defined in Section 1(d)). The Holder shall not be required to deliver the original Warrant in order to effect an exercise hereunder. Execution and delivery of the Exercise Notice with respect to less than all of the Warrant Shares
shall have the same effect as cancellation of the original Warrant and issuance of a new Warrant evidencing the right to purchase the remaining number of Warrant Shares. On or before the first (1st) Trading Day following the date on which the Company has
received the Exercise Notice), the Company shall transmit by facsimile an acknowledgment of confirmation of receipt of the Exercise Notice to the Holder and the Company’s transfer agent (the “Transfer Agent”). On or before the
third (3rd) Trading Day following the date on which
the Company has received the Exercise Notice (the “Share Delivery Date”) so long as the Holder delivers the Aggregate Exercise Price (or notice of a Cashless exercise) on or prior to the Share Delivery Date, the Company shall
(X) provided that the Transfer Agent is participating in The Depository Trust Company (“DTC”) Fast Automated Securities Transfer Program, upon the request of the Holder, credit such aggregate number of Warrant Shares to which
the Holder is entitled pursuant to such exercise to the Holder’s or its designee’s balance account with DTC through its Deposit / Withdrawal At Custodian system, or (Y) if the Transfer Agent is not participating in the DTC Fast
Automated Securities Transfer Program, issue and dispatch by overnight courier to the address as specified in the Exercise Notice, a certificate, registered in the Company’s share register in the name of the Holder or its designee, for the
number of shares of Common Stock to which the Holder is entitled pursuant to such exercise. The Company shall be responsible for all fees and expenses of the Transfer Agent and all fees and expenses with respect to the issuance of Warrant Shares via
DTC, if any. Upon delivery of the Exercise Notice, so long as the Holder delivers the Aggregate Exercise Price (or notice of a Cashless Exercise) on or prior to the Share Delivery Date, the Holder shall be deemed for all corporate purposes to have
become the holder of record of the Warrant Shares with respect to which this Warrant has been exercised, irrespective of the date such Warrant Shares are credited to the Holder’s DTC account or the date of delivery of the certificates
evidencing such Warrant Shares, as the case may be. If this Warrant is submitted in connection with any exercise pursuant to this Section 1(a) and the number of Warrant Shares represented by this Warrant submitted for exercise is greater than
the number of Warrant Shares being acquired upon an exercise, then the Company shall as soon as practicable and in no event later than three (3) Trading Days after any exercise and at its own expense, issue a new Warrant (in accordance with
Section 7(d)) representing the right to purchase the number of Warrant Shares issuable immediately prior to such exercise under this Warrant, less the number of Warrant Shares with respect to which this Warrant is exercised. No

  

 - 2 - 

 
fractional shares of Common Stock are to be issued upon the exercise of this Warrant, but rather the number of shares of Common Stock to be issued shall be rounded up to the nearest whole number.
The Company shall pay any and all taxes which may be payable with respect to the issuance and delivery of Warrant Shares upon exercise of this Warrant. 
 (b) Exercise Price. For purposes of this Warrant, “Exercise Price” means $1.45, subject to adjustment as provided herein. 

(c) Company’s Failure to Timely Deliver Securities. If the Company shall fail for any reason or for no reason to issue to
the Holder within three (3) Trading Days of receipt of the Exercise Notice, so long as the Holder delivers the Aggregate Exercise Price (or notice of Cashless Exercise) on or prior to the Share Delivery Date, a certificate for the number of
shares of Common Stock to which the Holder is entitled and register such shares of Common Stock on the Company’s share register or to credit the Holder’s balance account with DTC for such number of shares of Common Stock to which the
Holder is entitled upon the Holder’s exercise of this Warrant or pursuant to the Company’s obligation pursuant to clause (ii) below, and if on or after such Trading Day the Holder purchases (in an open market transaction or otherwise)
shares of Common Stock to deliver in satisfaction of a sale by the Holder of shares of Common Stock issuable upon such exercise that the Holder anticipated receiving from the Company (a “Buy-In”), then the Company shall, within
three (3) Trading Days after the Holder’s request and in the Holder’s discretion, either (i) pay cash to the Holder in an amount equal to the Holder’s total purchase price (including brokerage commissions and other
reasonable out-of-pocket expenses, if any) for the shares of Common Stock so purchased (the “Buy-In Price”), at which point the Company’s obligation to deliver such certificate (and to issue such shares of Common Stock) or
credit such Holder’s balance account with DTC shall terminate, or (ii) promptly honor its obligation to deliver to the Holder a certificate or certificates representing such shares of Common Stock or credit such Holder’s balance
account with DTC and pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In Price over the product of (A) such number of shares of Common Stock, times (B) the Closing Bid Price on the date of exercise. 

(d) Cashless Exercise. Notwithstanding anything contained herein to the contrary, if, after the Effective Date, any Warrant
Shares that are the subject of the Exercise Notice cannot be issued pursuant to Section 1145 of the Bankruptcy Code (as defined in the Securities Purchase Agreement) or is otherwise not freely transferable without any restrictions or
limitations, the Holder may, in its sole discretion, exercise this Warrant in whole or in part and, in lieu of making the cash payment otherwise contemplated to be made to the Company upon such exercise in payment of the Aggregate Exercise Price,
elect instead to receive upon such exercise the “Net Number” of shares of Common Stock determined according to the following formula (a “Cashless Exercise”): 

Net Number = (A x B) - (A x C) 
                                   
  B 

  
 - 3 -

 For purposes of the foregoing formula: 

 

			
	A=	 	the total number of shares with respect to which this Warrant is then being exercised.
		
	B=	 	the Weighted Average Price of the Common Stock (as reported by Bloomberg) for the five (5) consecutive Trading Days ending on the date immediately preceding the date of the
Exercise Notice.
		
	C=	 	the Exercise Price then in effect for the applicable Warrant Shares at the time of such exercise.

(e) Disputes. In the case of a dispute as to the determination of the Exercise Price or the arithmetic calculation of the Warrant
Shares, the Company shall promptly issue to the Holder the number of Warrant Shares that are not disputed and resolve such dispute in accordance with Section 12. 
 (f) Limitations on Exercises. The Company shall not effect the exercise of this Warrant, and the Holder shall not have the right to exercise this Warrant, to the extent that after giving effect to
such exercise, such Person (together with such Person’s affiliates) would beneficially own in excess of 4.99% (the “Maximum Percentage”) of the shares of Common Stock outstanding immediately after giving effect to such
exercise. For purposes of the foregoing sentence, the aggregate number of shares of Common Stock beneficially owned by such Person and its affiliates shall include the number of shares of Common Stock issuable upon exercise of this Warrant with
respect to which the determination of such sentence is being made, but shall exclude shares of Common Stock which would be issuable upon (i) exercise of the remaining, unexercised portion of this Warrant beneficially owned by such Person and
its affiliates and (ii) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company beneficially owned by such Person and its affiliates (including, without limitation, any convertible notes or
convertible preferred stock or warrants) subject to a limitation on conversion or exercise analogous to the limitation contained herein. Except as set forth in the preceding sentence, for purposes of this paragraph, beneficial ownership shall be
calculated in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended (the “1934 Act”). For purposes of this Warrant, in determining the number of outstanding shares of Common Stock, the Holder may rely
on the number of outstanding shares of Common Stock as reflected in (1) the Company’s most recent Form 10-K, Form 10-Q, Current Report on Form 8-K or other public filing with the Securities and Exchange Commission, as the case may be,
(2) a more recent public announcement by the Company or (3) any other notice by the Company or the Transfer Agent setting forth the number of shares of Common Stock outstanding. For any reason at any time, upon the written or oral request
of the Holder, the Company shall within one (1) Business Day 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 
  

 - 4 - 

 
conversion or exercise of securities of the Company, including the SPA Warrants, by the Holder and its affiliates since the date as of which such number of outstanding shares of Common Stock was
reported. By written notice to the Company, the Holder may from time to time increase or decrease the Maximum Percentage to any other percentage not in excess of 9.99% specified in such notice; provided that (i) any such increase will not be
effective until the sixty-first (61st) day after such
notice is delivered to the Company, and (ii) any such increase or decrease will apply only to the Holder and not to any other holder of SPA Warrants. The provisions of this paragraph shall be construed and implemented in a manner otherwise than
in strict conformity with the terms of this Section 1(f) 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. 
 (g) Insufficient Authorized Shares. If
at any time while this Warrant remains outstanding the Company does not have a sufficient number of authorized and unreserved shares of Common Stock to satisfy its obligation to reserve for issuance upon exercise of this Warrant at least a number of
shares of Common Stock equal to 130% (the “Required Reserve Amount”) of the maximum number of shares of Common Stock as shall from time to time be necessary to effect the exercise of all of this Warrant then outstanding (an
“Authorized Share Failure”), then the Company shall immediately take all action necessary to increase the Company’s authorized shares of Common Stock to an amount sufficient to allow the Company to reserve the Required Reserve
Amount for this Warrant then outstanding. Without limiting the generality of the foregoing sentence, as soon as practicable after the date of the occurrence of an Authorized Share Failure, but in no event later than sixty (60) days after the
occurrence of such Authorized Share Failure, the Company shall hold a meeting of its stockholders for the approval of an increase in the number of authorized shares of Common Stock. In connection with such meeting, the Company shall provide each
stockholder with a proxy statement and shall use its reasonable best efforts to solicit its stockholders’ approval of such increase in authorized shares of Common Stock and to cause its board of directors to recommend to the stockholders that
they approve such proposal. 
 2. ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES. The Exercise Price and the
number of Warrant Shares shall be adjusted from time to time as follows: 
 (a) Adjustment upon Issuance of shares of Common
Stock. If and whenever on or after the Subscription Date, the Company issues or sells, or in accordance with this Section 2 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 in the SPA Securities)) 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 an amount equal to the New Issuance Price. Upon each such adjustment of the Exercise Price hereunder, the number of Warrant
Shares issuable immediately prior to such Dilutive Issuance shall be adjusted to the number of shares of Common Stock determined by multiplying the Exercise Price in effect immediately prior to such

  

 - 5 - 

 
adjustment by the number of Warrant Shares acquirable upon exercise of this Warrant immediately prior to such adjustment and dividing the product thereof by the Exercise Price resulting from such
adjustment. For purposes of determining the adjusted Exercise Price under this Section 2(a), the following shall be applicable: 
 (i) Issuance of Options. If the Company in any manner grants any Options 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 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 2(a)(i), 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 or number of Warrant Shares 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. 
 (ii) 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 2(a)(ii), 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 

 

 - 6 - 

 
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 2(a), no further adjustment of the Exercise Price or number of Warrant Shares shall be made by reason of such issue or sale. 
 (iii) Change in Option Price or Rate of Conversion. If the purchase price provided for in any Options issued after the Subscription Date, the additional consideration, if any, payable upon the
issue, conversion, exercise or exchange of any Convertible Securities issued after the Subscription Date, or the rate at which any Convertible Securities issued after the Subscription Date are convertible into or exercisable or exchangeable for
shares of Common Stock increases or decreases at any time, the Exercise Price and the number of Warrant Shares in effect at the time of such increase or decrease shall be adjusted to the Exercise Price and the number of Warrant Shares 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. Additionally, if the terms of any Option or Convertible Security that was outstanding as of the date of the Subscription Date is 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, but in such event the amount of the
adjustment to the Exercise Price pursuant to this Section 2 will not be proportionately greater than the proportionate amount of the increase or decrease. No adjustment pursuant to this Section 2(a) shall be made if such adjustment would
result in an increase of the Exercise Price then in effect or a decrease in the number of Warrant Shares. 
 (iv) 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 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 or receivable by the Company therefor. If any shares 

 

 - 7 - 

 
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 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. 
 (c) Adjustment upon Subdivision or Combination of shares of Common Stock.
If the Company at any time on or after the Subscription Date subdivides (by any stock split, stock dividend, recapitalization or otherwise) one or more classes of its outstanding shares of Common Stock into a greater number of shares, the Exercise
Price in effect immediately prior to such subdivision will be proportionately reduced and the number of Warrant Shares will be proportionately increased. If the Company at any time on or after the Subscription Date combines (by combination, reverse
stock split or otherwise) one or more classes of its outstanding shares of Common Stock into a smaller number of shares, the Exercise Price in effect immediately prior to such combination will be proportionately increased and the

  

 - 8 - 

 
number of Warrant Shares will be proportionately decreased. Any adjustment under this Section 2(c) shall become effective at the close of business on the date the subdivision or combination
becomes effective. 
 (d) Holder’s Right of Alternative Exercise Price Following Issuance of Variable Securities.
If the Company issues or sells or, in accordance with this Section 2 is deemed to have issued or sold any Options or Convertible Securities after the Issuance Date that are convertible into or exchangeable or exercisable for shares of Common
Stock at a price which varies or may vary with the market price of the shares of Common Stock, including by way of one or more reset(s) to a fixed price (each of the formulations for such variable price being herein referred to as, a
“Variable Price Formulation”), the Company shall provide written notice thereof via facsimile and overnight courier to the Holder (the “Variable Notice”) on the date of issuance or deemed issuance of such
Convertible Securities or Options. From and after the date the Company issues or is deemed to have issued any such Convertible Securities or Options with a Variable Price Formulation, but only for so long as such Convertible Securities or Options
are outstanding, the Holder shall have the right, but not the obligation, in its sole discretion to substitute any of the applicable Variable Price Formulation for the Exercise Price upon exercise of the Warrants held by it by designating in the
Exercise Notice delivered upon exercise of such Warrant that solely for purposes of such exercise the Holder is relying on the Variable Price Formulation rather than the Exercise Price then in effect. The Holder’s election to rely on a Variable
Price Formulation for a particular exercise of Warrants shall not obligate the Holder to rely on a Variable Price Formulation for any future exercise of Warrants. In connection with determining the “lowest price per share for which one share of
Common Stock is issuable upon exercise of any Option” pursuant to Section 2(a)(i) and the “lowest price per share for which one share of Common Stock is issuable upon the conversion, exercise or exchange of a Convertible
Security” pursuant to Section 2(a)(ii), as such terms pertain solely to any Variable Price Formulation contained in any Option or Convertible Securities issued after the Issuance Date, such lowest price shall equal the lesser of
(i) the fixed exercise, conversion or exchange price set forth in the applicable Option or Convertible Security and (ii) the Variable Price Formulation contained in the applicable Option or Convertible Security, calculated as if such
Option or Convertible Security were converted, exercised or exchanged as of the date of issuance of the applicable Option or Convertible Security. 
 (e) Price Adjusted Market Price Adjustment. If the Price Adjusted Market Price is less than the Exercise Price in effect on the Issuance Date, then on December 22, 2010, the Exercise Price
then in effect shall be reduced (but in no event increased) to 120% of the Price Adjusted Market Price, provided that the Exercise Price shall not be reduced below $0.60 (subject to adjustment for stock splits, stock dividends, recapitalizations or
other similar events with respect to the Company’s Common Stock) pursuant to this Section 2(e). For the avoidance of doubt, if the adjustment in the immediately preceding sentence would otherwise result in an increase in the Exercise Price
hereunder, no adjustment shall be made. Upon the foregoing adjustment to the Exercise Price, the number of Warrant Shares issuable immediately prior to such adjustment shall be adjusted to the number of shares of Common Stock determined by
multiplying .9375 by the product of (A) the Exercise Price in effect immediately prior to such adjustment and (B) the number of Warrant Shares acquirable upon exercise in full of this Warrant immediately prior to such adjustment and dividing the
product thereof by the Exercise Price resulting from such adjustment.

 3. RIGHTS UPON DISTRIBUTION OF ASSETS. 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, upon an exercise of this Warrant, in whole or in part, the Holder will be entitled to receive the amount of any such Distribution that the Holder would have received if the Holder had held, immediately before the date on which a record is
taken for the declaration or payment of the Distribution, or, if no such record date is taken, the date as of which the record holders of shares of Common Stock are to be determined for the declaration or payment of the Distribution, the number of
shares of Common Stock that the Holder is entitled to receive upon such exercise (without taking into account any limitations or restrictions on the convertibility of this Warrant). 

4. PURCHASE RIGHTS; FUNDAMENTAL TRANSACTIONS. 
 (a) Purchase Rights. In addition to any adjustments pursuant to Section 2 above, if at any time the Company grants, issues or sells any Options, Convertible Securities or rights to purchase
stock, warrants, securities or other property pro rata to the record holders of any class 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 the exercise of this Warrant)
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. 
 (b) Fundamental Transactions. The Company shall not enter into or be party to
a Fundamental Transaction unless (i) the Successor Entity assumes 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 (4)(b) pursuant to
written agreements in form and substance satisfactory to the Required Holders and approved by the Required Holders prior to such Fundamental Transaction, including agreements to deliver to each holder of the SPA Warrants in exchange for such
Warrants a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to this Warrant, including, without limitation, an adjusted exercise price equal to the value for the shares of Common Stock
reflected by the terms of such Fundamental Transaction, and exercisable for a corresponding number of shares of capital stock 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 satisfactory to the Required Holders and (ii) the Successor Entity (including its Parent Entity) is a publicly traded corporation whose common stock is
quoted on or listed for trading on an Eligible Market. Upon the occurrence of any Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Fundamental Transaction, the provisions
of this Warrant referring to the “Company” shall refer instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations of the Company under this Warrant with

  

 - 10 - 

 
the same effect as if such Successor Entity had been named as the Company herein. Upon consummation of the Fundamental Transaction, the Successor Entity shall deliver to the Holder confirmation
that there shall be issued upon exercise of this Warrant at any time after the consummation of the Fundamental Transaction, in lieu of the shares of Common Stock (or other securities, cash, assets or other property) issuable upon the exercise of the
Warrant prior to such Fundamental Transaction, such shares of the publicly traded common stock or common shares (or its equivalent) of the Successor Entity (including its Parent Entity) which the Holder would have been entitled to receive upon the
happening of such Fundamental Transaction had this Warrant been converted immediately prior to such Fundamental Transaction, as adjusted in accordance with the provisions of this Warrant. In addition to and not in substitution for any other rights
hereunder, prior to the consummation of any Fundamental Transaction pursuant to which holders of shares of Common Stock are entitled to receive securities or other assets with respect to or in exchange for shares of Common Stock (a
“Corporate Event”), the Company shall make appropriate provision to insure that the Holder will thereafter have the right to receive upon an exercise of this Warrant at any time after the consummation of the Corporate Event but
prior to the Expiration Date, in lieu of shares of Common Stock (or other securities, cash, assets or other property) purchasable upon the exercise of this Warrant prior to such Corporate Event, such shares of stock, securities, cash, assets or any
other property whatsoever (including warrants or other purchase or subscription rights) which the Holder would have been entitled to receive upon the happening of such Corporate Event had this Warrant been exercised immediately prior to such
Corporate Event. Provision made pursuant to the preceding sentence shall be in a form and substance reasonably satisfactory to the Required Holders. The provisions of this Section shall apply similarly and equally to successive Fundamental
Transactions and Corporate Events and shall be applied without regard to any limitations on the exercise of this Warrant. 
 (c) Notwithstanding the foregoing, in the event of a Change of Control, at the request of the Holder delivered before the ninetieth (90th) day after the consummation of such Change of Control, the Company (or the Successor Entity) shall purchase this
Warrant from the Holder by paying to the Holder, within five (5) Business Days after such request (or, if later, on the effective date of the Change of Control), cash in an amount equal to the Black Scholes Value of the remaining unexercised
portion of this Warrant on the date of such Change of Control. 
 5. NONCIRCUMVENTION. The Company hereby covenants and
agrees that the Company will not, by amendment of its Certificate of Incorporation or Bylaws, or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, 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, and will at all times in good faith carry out all the provisions of this Warrant and take all action as may be required to protect the rights
of the Holder. Without limiting the generality of the foregoing, the Company (i) shall not increase the par value of any shares of Common Stock receivable upon the exercise of this Warrant above the Exercise Price then in effect,
(ii) shall take all such actions as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable shares of Common Stock upon the exercise of this Warrant, and (iii) shall, so long as
any of the SPA Warrants are outstanding, take all action necessary to reserve and keep available out of its authorized and unissued shares of Common Stock, solely for the purpose of effecting the exercise of the SPA Warrants, 130% of the number of
shares of Common Stock as shall from time to time be necessary to effect the exercise of the SPA Warrants then outstanding (without regard to any limitations on exercise). 

 

 - 11 - 

 6. WARRANT HOLDER NOT DEEMED A STOCKHOLDER. Except as otherwise specifically provided
herein, the Holder, solely in such Person’s capacity as a holder of this Warrant, shall not be entitled to vote or receive dividends or be deemed the holder of share capital of the Company for any purpose, nor shall anything contained in this
Warrant be construed to confer upon the Holder, solely in such Person’s capacity as the Holder of this Warrant, any of the rights of a stockholder of the Company or any right to vote, give or withhold consent to any corporate action (whether
any reorganization, issue of stock, reclassification of stock, consolidation, merger, conveyance or otherwise), receive notice of meetings, receive dividends or subscription rights, or otherwise, prior to the issuance to the Holder of the Warrant
Shares which such Person is then entitled to receive upon the due exercise of this Warrant. In addition, nothing contained in this Warrant shall be construed as imposing any liabilities on the Holder to purchase any securities (upon exercise of this
Warrant or otherwise) or as a stockholder of the Company, whether such liabilities are asserted by the Company or by creditors of the Company. Notwithstanding this Section 6, the Company shall provide the Holder with copies of the same notices
and other information given to the stockholders of the Company generally, contemporaneously with the giving thereof to the stockholders. 
 7. REISSUANCE OF WARRANTS. 
 (a) Transfer of Warrant. If this
Warrant is to be transferred, the Holder shall surrender this Warrant to the Company, whereupon the Company will forthwith issue and deliver upon the order of the Holder a new Warrant (in accordance with Section 7(d)), registered as the Holder
may request, representing the right to purchase the number of Warrant Shares being transferred by the Holder and, if less than the total number of Warrant Shares then underlying this Warrant is being transferred, a new Warrant (in accordance with
Section 7(d)) to the Holder representing the right to purchase the number of Warrant Shares not being transferred. 
 (b)
Lost, Stolen or Mutilated Warrant. Upon receipt by the Company of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant, and, in the case of loss, theft or destruction, of any
indemnification undertaking by the Holder to the Company in customary form and, in the case of mutilation, upon surrender and cancellation of this Warrant, the Company shall execute and deliver to the Holder a new Warrant (in accordance with
Section 7(d)) representing the right to purchase the Warrant Shares then underlying this Warrant. 
 (c) Exchangeable
for Multiple Warrants. This Warrant is exchangeable, upon the surrender hereof by the Holder at the principal office of the Company, for a new Warrant or Warrants (in accordance with Section 7(d)) representing in the aggregate the right to
purchase the number of Warrant Shares then underlying this Warrant, and each such new Warrant will represent the right to purchase such portion of such Warrant Shares as is designated by the Holder at the time of such surrender; provided, however,
that no Warrants for fractional shares of Common Stock shall be given. 
  

 - 12 - 

 (d) Issuance of New Warrants. Whenever the Company is required to issue a new
Warrant pursuant to the terms of this Warrant, such new Warrant (i) shall be of like tenor with this Warrant, (ii) shall represent, as indicated on the face of such new Warrant, the right to purchase the Warrant Shares then underlying this
Warrant (or in the case of a new Warrant being issued pursuant to Section 7(a) or Section 7(c), the Warrant Shares designated by the Holder which, when added to the number of shares of Common Stock underlying the other new Warrants issued
in connection with such issuance, does not exceed the number of Warrant Shares then underlying this Warrant), (iii) shall have an issuance date, as indicated on the face of such new Warrant which is the same as the Issuance Date, and
(iv) shall have the same rights and conditions as this Warrant. 
 8. NOTICES. Whenever notice is required to be
given under this Warrant, unless otherwise provided herein, such notice shall be given in accordance with Section 9(f) of the Securities Purchase Agreement. The Company shall provide the Holder with prompt written notice of all actions taken
pursuant to this Warrant, including in reasonable detail a description of such action and the reason therefor. Without limiting the generality of the foregoing, the Company will give written notice to the Holder (i) immediately upon any
adjustment of the Exercise Price, setting forth in reasonable detail, and certifying, the calculation of such adjustment and (ii) at least fifteen (15) days prior to the date on which the Company closes its books or takes a record
(A) with respect to any dividend or distribution upon the shares of Common Stock, (B) with respect to any grants, issuances or sales of any Options, Convertible Securities or rights to purchase stock, warrants, securities or other property
to holders of shares of Common Stock or (C) for determining rights to vote with respect to any Fundamental Transaction, dissolution or liquidation, provided in each case that such information shall be made known to the public prior to or in
conjunction with such notice being provided to the Holder. 
 9. AMENDMENT AND WAIVER. Except as otherwise provided
herein, the provisions of this Warrant may be amended and the Company may take any action herein prohibited, or omit to perform any act herein required to be performed by it, only if the Company has obtained the written consent of the Required
Holders. No such amendment shall be effective to the extent that it applies to less than all of the holders of the SPA Warrants then outstanding. 
 10. GOVERNING LAW. This Warrant shall be governed by and construed and enforced in accordance with, and all questions concerning the construction, validity, interpretation and performance of this
Warrant shall be governed by, the internal laws of the State of Florida, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of Florida or any other jurisdictions) that would cause the application of
the laws of any jurisdictions other than the State of Florida. The Holder and the Company hereby irrevocably submit to the exclusive jurisdiction of the Bankruptcy Court for the adjudication of any dispute hereunder or in connection herewith or with
any transaction contemplated hereby or discussed herein, and hereby irrevocably waive, and agree 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 brought in an inconvenient forum or that the venue of such suit, action or proceeding is improper. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law.
Nothing contained herein shall be deemed or operate to preclude the Holder from bringing suit or taking other legal action against the Company in any other jurisdiction to collect on the Company’s obligations to the Holder, to

  

 - 13 - 

 
realize on any collateral or any other security for such obligations, or to enforce a judgment or other court ruling in favor of the Holder. THE COMPANY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT
MAY HAVE, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION WITH OR ARISING OUT OF THIS WARRANT OR ANY TRANSACTION CONTEMPLATED HEREBY. 

11. CONSTRUCTION; HEADINGS. This Warrant shall be deemed to be jointly drafted by the Company and all the Buyers and shall not be
construed against any person as the drafter hereof. The headings of this Warrant are for convenience of reference and shall not form part of, or affect the interpretation of, this Warrant. 

12. DISPUTE RESOLUTION. In the case of a dispute as to the determination of the Exercise Price or the arithmetic calculation of
the Warrant Shares, the Company shall submit the disputed determinations or arithmetic calculations via facsimile within two (2) Business Days of receipt of the Exercise Notice giving rise to such dispute, as the case may be, to the Holder. If
the Holder and the Company are unable to agree upon such determination or calculation of the Exercise Price or the Warrant Shares within three (3) Business Days of such disputed determination or arithmetic calculation being submitted to the
Holder, then the Company shall, within two (2) Business Days submit via facsimile (a) the disputed determination of the Exercise Price to an independent, reputable investment bank selected by the Company and approved by the Holder or
(b) the disputed arithmetic calculation of the Warrant Shares to the Company’s independent, outside accountant. The Company shall cause at its expense the investment bank or the accountant, as the case may be, to perform the determinations
or calculations and notify the Company and the Holder of the results no later than ten Business Days from the time it receives the disputed determinations or calculations. Such investment bank’s or accountant’s determination or
calculation, as the case may be, shall be binding upon all parties absent demonstrable error. 
 13. REMEDIES, OTHER
OBLIGATIONS, BREACHES AND INJUNCTIVE RELIEF. The remedies provided in this Warrant shall be cumulative and in addition to all other remedies available under this Warrant and the other Transaction Documents, at law or in equity (including a
decree of specific performance and/or other injunctive relief), and nothing herein shall limit the right of the Holder to pursue actual damages for any failure by the Company to comply with the terms of this Warrant. 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
of this Warrant 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. 

14. TRANSFER. This Warrant may be offered for sale, sold, transferred or assigned without the consent of the Company, except as
may otherwise be required by Section 2(f) of the Securities Purchase Agreement. 
 15. SEVERABILITY. If any
provision of this Warrant is prohibited by law or otherwise determined to be invalid or unenforceable by a court of competent jurisdiction, the 

  
 - 14 -

 
provision that would otherwise be prohibited, invalid or unenforceable shall be deemed amended to apply to the broadest extent that it would be valid and enforceable, and the invalidity or
unenforceability of such provision shall not affect the validity of the remaining provisions of this Warrant so long as this Warrant as so modified continues to express, without material change, the original intentions of the parties as to the
subject matter hereof and the prohibited nature, invalidity or unenforceability of the provision(s) in question does not substantially impair the respective expectations or reciprocal obligations of the parties or the practical realization of the
benefits that would otherwise be conferred upon the parties. The parties will endeavor in good faith negotiations to replace the prohibited, invalid or unenforceable provision(s) with a valid provision(s), the effect of which comes as close as
possible to that of the prohibited, invalid or unenforceable provision(s). 
 16. CERTAIN DEFINITIONS. For purposes of
this Warrant, the following terms shall have the following meanings: 
 (a) “Black Scholes Value” means the
