 (d) Adjustment to Conversion Price. The Conversion Price in effect at any time shall be

 (i) Common Stock Dividends; Common Stock
Splits; Reverse Common Stock Splits. If the Company, at any time while this Note is outstanding, (A) shall pay a stock dividend on its Common Stock, (B) subdivide outstanding shares of Common Stock into a larger number of shares, or
(C) combine outstanding shares of Common Stock into a smaller number of shares, the Conversion Price shall be multiplied by a fraction the numerator of which shall be the number of shares of Common Stock (excluding treasury shares, if any)
outstanding before such event and the denominator of which shall be the number of shares of Common Stock outstanding after such event. Any adjustment made pursuant to this Section 3(d)(i) shall become effective immediately after the record date
for the determination of stockholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or re-classification. 

(ii) Subscription Rights. If the Company, at any time while this Note is outstanding, shall fix a record date for the distribution to
all of the holders of Common Stock evidence of its indebtedness or assets or rights, options, warrants or other securities entitling them to subscribe for, purchase, convert to, exchange for or to otherwise acquire any security (excluding those
referred to in Section 3(d)(i) above), then in each such case the Conversion Price at which this Note shall thereafter be exercisable shall be determined by multiplying the Conversion Price in effect immediately prior to the record date fixed
for determination of stockholders entitled to receive such distribution by a fraction, the denominator of which shall be the average Daily Market Price of the Common Stock for the ten (10) Trading Days prior to the record date mentioned above,
and the numerator of which shall be such average Daily Market Price of the Common Stock for the ten (10) Trading Days prior to such record date less the then fair market value at such record date of the portion of such evidence of indebtedness
or assets or rights, options, warrants or other securities so distributed applicable to one outstanding share of Common Stock as determined by the Board of Directors in good faith; provided, however, that in the event of a distribution
exceeding twenty percent (20%) of the net assets of the Company, such fair market value shall be determined by an appraiser selected by the Holder and reasonably acceptable to the Company. The Company shall pay for all such appraisals. Such
adjustment shall be made whenever any such distribution is made and shall become effective immediately after the record date mentioned above. 

(iii) Other Events. In case of (A) any reclassification of the Common Stock into other securities of the Company, (B) any
compulsory share exchange pursuant to which the Common Stock is converted into other securities, cash or property or (C) any merger or consolidation with or into any persons, or any sale or other disposition of all or substantially all of the
assets of the Company to any person (each of (A), (B) or (C), an “Extraordinary Event”), the Holder shall have the right thereafter to convert this Note into shares of stock and other securities, cash and property receivable
upon or deemed to be held by holders of Common Stock following such Extraordinary Event, that the Holder would have been entitled to receive had it converted this Note immediately prior to such Extraordinary Event (without taking into account any
limitations or restrictions on the convertibility of this Note). In the case of an Extraordinary Event, the terms of any such Extraordinary Event shall include such terms so as to continue to give to the Holder the right to receive the securities,
cash or property set forth in this Section 3(d)(iii) upon any conversion following such Extraordinary Event. This provision shall similarly apply to successive Extraordinary Events. For the avoidance of doubt, nothing contained in this clause
(iii) shall be construed to impair the Company’s or the Holder’s rights under Section 5.

per share less than the Conversion Price in effect immediately prior to the time of such issue or sale, then and in each such case (a “Trigger Issuance”) the then-existing Conversion Price shall be reduced, as of the close of
business on the effective date of the Trigger Issuance, to the lowest price per share at which any share of Common Stock was issued or sold or deemed to be issued or sold in the Trigger Issuance. For purposes of this subsection (iv),
“Additional Shares of Common Stock” means all shares of Common Stock issued by the Company or deemed to be issued pursuant to this subsection (iv), other than Excluded Issuances (as defined in subsection (v) hereof).

stock or security convertible into or exchangeable for Common Stock (such warrants, rights or options being called “Options” and such convertible or exchangeable stock or securities being called “Convertible
Securities”) whether or not such Options or the right to convert or exchange any such Convertible Securities are immediately exercisable, and the price per share for which Common Stock is issuable upon the exercise of such Options or upon
the conversion or exchange of such Convertible Securities (determined by dividing (i) the sum (which sum shall constitute the applicable consideration) of (x) the total amount, if any, received or receivable by the Company as consideration
for the granting of such Options, plus (y) the aggregate amount of additional consideration payable to the Company upon the exercise of all such Options, plus (z), in the case of such Options which relate to Convertible Securities, the
aggregate amount of additional consideration, if any, payable upon the issue or sale of such Convertible Securities and upon the conversion or exchange thereof, by (ii) the total maximum number of shares of Common Stock issuable upon the
exercise of such Options or upon the conversion or exchange of all such Convertible Securities issuable upon the exercise of such Options) shall be less than the Conversion Price in effect immediately prior to the time of the granting of such
Options, then the total number of shares of Common Stock issuable upon the exercise of such Options or upon conversion or exchange of the total amount of such Convertible Securities issuable upon the exercise of such Options shall be deemed to have
been issued for such price per share as of the date of granting of such Options and thereafter shall be deemed to be outstanding for purposes of adjusting the Conversion Price. Except as otherwise provided in subsection (iv)(D), no adjustment of the
Conversion Price shall be made upon the actual issue of such Common Stock or of such Convertible Securities upon exercise of such Options or upon the actual issue of such Common Stock upon conversion or exchange of such Convertible Securities. 

  
 23 








 (B) Issuance of Convertible Securities. In case the Company shall in any manner issue
(directly and not by assumption in a merger or otherwise) or sell any Convertible Securities, whether or not the rights to exchange or convert any such Convertible Securities are immediately exercisable, and the price per share for which Common
Stock is issuable upon such conversion or exchange (determined by dividing (i) the sum (which sum shall constitute the applicable consideration) of (x) the total amount received or receivable by the Company as consideration for the issue
or sale of such Convertible Securities, plus (y) the aggregate amount of additional consideration, if any, payable to the Company upon the conversion or exchange thereof, by (ii) the total number of shares of Common Stock issuable upon the
conversion or exchange of all such Convertible Securities) shall be less than the Conversion Price in effect immediately prior to the time of such issue or sale, then the total maximum number of shares of Common Stock issuable upon conversion or
exchange of all such Convertible Securities shall be deemed to have been issued for such price per share as of the date of the issue or sale of such Convertible Securities and thereafter shall be deemed to be outstanding for purposes of adjusting
the Conversion Price, provided that (a) except as otherwise provided in subsection (iv)(D), no adjustment of the Conversion Price shall be made upon the actual issuance of such Common Stock upon conversion or exchange of such Convertible
Securities and (b) no further adjustment of the Conversion Price shall be made by reason of the issue or sale of Convertible Securities upon exercise of any Options to purchase any such Convertible Securities for which adjustments of the
Conversion Price have been made pursuant to the other provisions of subsection (iv). 
 (C) Change in Warrant Price or Amount.
Notwithstanding the provisions of subsection (iii), if the exercise price provided for in any warrants of the Company on the date hereof is below the Conversion Price and (i) such exercise price is reduced, the then-existing Conversion Price
shall be reduced, as of the close of business on the effective date of such reduction in exercise price by an amount equal to the product of (x) the original exercise price minus (y) the reduced exercise price and (2) a fraction, the
numerator of which is the number of shares of Common Stock that may be acquired upon exercise, if any, of the warrants whose exercise price is reduced and the denominator of which is the aggregate number of shares of Common Stock that may be
acquired upon exercise of all of the outstanding warrants or (ii) the Company amends the terms of such warrants to increase the number of shares of Common Stock that may be acquired upon exercise of the warrants, the then-existing Conversion
Price shall be reduced, as of the close of business on the effective date of amendment by an amount equal to the product of (1) (x) the original exercise price minus (y) the product of the original exercise price and a fraction, the
numerator of which is the old number of shares for which the warrants were exercisable immediately prior to such amendment and the denominator of which is the new number of shares for which the warrants are exercisable immediately following such
amendment and (2) a fraction, the numerator of which is the number of shares of Common Stock that may be acquired upon exercise, if any, of the warrants whose exercise price is reduced and the denominator of which is the aggregate number of
shares of Common Stock that may be acquired upon exercise of all of the outstanding warrants. 

  
 24 








 (D) Change in Option Price or Conversion Rate. Upon the happening of any of the following
events, namely, if the purchase price provided for in any Option referred to in subsection (iv)(A) hereof, the additional consideration, if any, payable upon the conversion or exchange of any Convertible Securities referred to in subsections (iv)(A)
or (iv)(B), or the rate at which Convertible Securities referred to in subsections (iv)(A) or (iv)(B) are convertible into or exchangeable for Common Stock shall change at any time (including, but not limited to, changes under or by reason of
provisions designed to protect against dilution), the Conversion Price in effect at the time of such event shall forthwith be readjusted to the Conversion Price which would have been in effect at such time had such Options or Convertible Securities
still outstanding provided for such changed purchase price, additional consideration or conversion rate, as the case may be, at the time initially granted, issued or sold. 

(E) Calculation of Consideration Received. If any Common Stock, Options or Convertible Securities are issued, granted or sold for cash,
the consideration received therefor will be the amount received by the Company therefor, after deduction of all underwriting discounts or allowances in connection with such issuance, grant or sale. In case any Common Stock, Options or Convertible
Securities are issued or sold for a consideration part or all of which shall be other than cash, including in the case of a strategic or similar arrangement in which the other entity will provide services to the Company, purchase services from the
Company or otherwise provide intangible consideration to the Company, the amount of the consideration other than cash received by the Company (including the net present value of the consideration expected by the Company for the provided or purchased
services) will be the fair market 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 average Daily Market Price for the ten
(10) Trading Days with respect to such securities thereof prior to the date of receipt. In case any Common Stock, Options or Convertible Securities are issued in connection with any merger or consolidation in which the Company is the surviving
Company, the amount of consideration therefor will be deemed to be the fair market value of such portion of the net assets and business of the non-surviving Company as is attributable to such Common Stock, Options or Convertible Securities, as the
case may be. Notwithstanding anything to the contrary contained herein, if Common Stock, Options or Convertible Securities are issued, granted or sold in conjunction with each other as part of a single transaction or in a series of related
transactions, and one or more of such securities are issued, granted or sold for a price below fair market value (when the aggregate value of such securities is compared with the aggregate amount of consideration received by the Company therefor),
the Holder may elect to determine the amount of consideration deemed to be received by the Company therefor by deducting the difference between the fair value of and the amount paid for any type of securities issued, granted or sold in such
transaction or series of transactions (the “Disregarded Securities”). If the Holder makes an election pursuant to the immediately preceding sentence, no adjustment to the Conversion Price shall be made pursuant to this subsection
(iv)(E) for the issuance of the Disregarded Securities or upon any conversion or exercise thereof. For example, if the Company were to issue convertible notes having a face value of $1,000,000 and warrants to purchase shares of Common Stock at an
exercise price equal to the market price of the Common Stock on the date of issuance of such warrants in exchange for $1,000,000 of consideration, the fair value of the warrants would be subtracted from the $1,000,000 of consideration received by
the Company for the purposes of determining the price per share of Common Stock issuable upon conversion of the convertible notes and for purposes of determining any adjustment to the Conversion Price hereunder as a result of the issuance of the
Convertible Securities. The Holder shall calculate, using standard commercial valuation methods appropriate for valuing such assets, the fair market value of any consideration other than cash or securities; provided, however, that if
the Company does not agree to such fair market value calculation within three (3) Business Days after receipt of such calculation along with reasonably detailed supporting documentation from the Holder, then such fair market value will be
determined in good faith by an investment banker or other appropriate expert of national reputation selected by the Holder (which investment banker or other expert shall not have been engaged or otherwise employed by the Holder within one
(1) year of the date of such engagement hereunder) and reasonably acceptable to the Company, with the costs of such appraisal to be borne by the Company. 

  
 25 








 (F) Other Action Affecting Conversion Price. If the Company takes any action affecting the
Common Stock after the date hereof that would be covered by this Section 3, but for the manner in which such action is taken or structured, which would in any way diminish the value of this Note then the Conversion Price shall be adjusted in
such manner as the Board of Directors of the Company shall in good faith determine to be equitable under the circumstances. 
 (G) Record
Date. In case the Company shall take a record of the holders of its Common Stock for the purpose of entitling them (i) to receive a dividend or other distribution payable in Common Stock, Options or Convertible Securities or (ii) to
subscribe for or purchase Common Stock, Options or Convertible Securities, then such record date shall 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, provided, however, that any such adjustment in the Conversion Price shall be reversed or shall
not become effective, as applicable, if the Company abandons the action to which the record date pertains. 

  
 26 








 (H) Treasury Shares. The number of shares of Common Stock outstanding at any given time
shall not include shares owned or held by or for the account of the Company or any of its wholly owned Subsidiaries, and the disposition of any such shares (other than the cancellation or retirement thereof) shall be considered an issue or sale of
Common Stock for the purpose of this subsection (iv). 
 (v) Excluded Issuances. Notwithstanding anything to the contrary contained
herein, the Company shall not be required to make any adjustment of the Conversion Price in the case of the issuance of (A) Common Stock, Options and Convertible Securities for a total consideration of less than $10,000,000 during any 24-month
period; (B) Common Stock, Options or Convertible Securities issued to employees or consultants of the Company in connection with their employment or engagement by the Company pursuant to an equity compensation plan in effect as of
April 26, 2013, or as approved by the Board of Directors, which are granted in the ordinary course of business and consistent with past practice; (C) Common Stock or Convertible Securities to employees or consultants of the Company in
connection with their employment or engagement by the Company pursuant to an equity purchase plan in effect as of April 26, 2013, or as approved by the Board of Directors, which are granted in the ordinary course of business and consistent with
past practice; (D) Common Stock upon the conversion or exercise of any warrants outstanding on the date hereof as disclosed in Schedule 3(d)(v), except as set forth in subsection (iv)(C) above; or (E) Common Stock, Options or
Convertible Securities that are issued at or above the market price at the time of issuance; and (F) Common Stock, Options or Convertible Securities approved by the Holder (collectively, “Excluded Issuances”). 

(vi) Weighted Average Adjustment for Issuances. In the event that at any time or from time to time the Company shall issue or sell
Common Stock, Options or Convertible Securities subject to Section 3(d)(iv) for no consideration or for a per share consideration that is greater than the applicable Conversion Price at the time of such issuance or sale but less at the time of
such issuance or sale than the Daily Market Price, then the Conversion Price in effect immediately prior to each such issuance or sale will immediately be reduced to the price determined by multiplying the Conversion Price, in effect immediately
prior to such issuance or sale, by a fraction, (A) the numerator of which shall be (x) the number of shares of Common Stock outstanding immediately prior to such issuance or sale plus (y) the number of shares of Common Stock which the
aggregate consideration received by the Company for the total number of such additional shares of Common Stock so issued or sold would purchase at the Daily Market Price on the last Trading Day immediately preceding such issuance or sale and
(B) the denominator of which shall be the number of shares of Common Stock outstanding immediately after such issue or sale. 

  
 27 








 (e) Fractional Shares. Upon a conversion hereunder, the Company shall not be required to
issue stock certificates representing fractions of shares of the Common Stock, but may if otherwise permitted, make a cash payment in respect of any final fraction of a share based on the closing bid price at such time. If the Company elects not, or
is unable, to make such a cash payment, the Holder shall be entitled to receive, in lieu of the final fraction of a share, one whole share of Common Stock. 

(f) Notice of Adjustments. Upon the occurrence of each adjustment or readjustment of the Conversion Price pursuant to this
Section 3, the Company, at its own expense, shall promptly compute such adjustment or readjustment and prepare and furnish to each Holder a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which
such adjustment or readjustment is based. The Company shall, upon the written request at any time of the Holder, furnish to such Holder a like certificate setting forth (i) such adjustment or readjustment, (ii) the Conversion Price at the
time in effect and (iii) the number of shares of Common Stock and the amount, if any, of other securities or property which at the time would be received upon conversion of this Note. 

4. Redemption. 
 (a)
Optional Redemption. 
 (i) The Company may redeem this Note, in whole or in part, at any time, at a redemption price (the
“Optional Redemption Price”) equal to the principal amount of this Note, plus accrued and unpaid interest thereon through the date of such redemption, if at the time of any such redemption all of the Common Stock into which this
Note (or a portion thereof subject to such redemption) is convertible is freely transferable by the Holder without any restriction pursuant to registration or exemption under all applicable United States federal and state securities laws (such
redemption, an “Optional Redemption”); provided, that the minimum amount of Notes to be redeemed under any single Optional Redemption shall not be less than $500,000. Notwithstanding anything to the contrary in this
Section 4(a), until the Optional Redemption Price is paid, in full, the Holder may convert all or any part of the outstanding principal amount of this Note, plus accrued interest thereof through the Conversion Date, into a number of Conversion
Shares in accordance with Section 3 hereof. 
 (ii) The Company shall give written notice in respect of an Optional Redemption to each
Holder pursuant to Section 11 at least twenty (20) but not more than thirty (30) days before the date of such Optional Redemption (the “Optional Redemption Date”). In the case of any Optional Redemption of the Notes
in part, the balance of the Notes to be redeemed pursuant to Section 4(a)(i) shall be allocated among all of the Notes at the time outstanding in proportion, as nearly as practicable, to the respective unpaid principal balances thereof. The
Company shall apply any amounts to be used for Optional Redemption pursuant to this Section 4(a), first, to pay accrued and unpaid interest on the Notes, if any, then to redeem the principal amount of the Notes or any portion thereof. Each
notice in respect of an Optional Redemption given pursuant to this Section 4(a)(ii) shall state (A) the Optional Redemption Date, (B) the projected Optional Redemption Price of the Notes to be redeemed, (C) in the case of an
Optional Redemption of the Notes in part, the portion of the outstanding balance of the Notes that is expected to be redeemed and the aggregate balance of Notes to be outstanding after such partial Optional Redemption, (D) that Notes to be
redeemed in an Optional Redemption in whole must be surrendered (which action may be taken by any Holder or its authorized agent) to the Company to collect the Optional Redemption Price on such Notes, and specifying the procedures for such surrender
and (E) that, unless the Company fails to pay the Optional Redemption Price, interest on Notes (or the portion thereof) called for Optional Redemption shall cease to accrue after the Optional Redemption Date. 

  
 28 








 (iii) If notice in respect of an Optional Redemption for any Notes shall have been given as
provided in Section 4(a)(ii), such Notes shall become due and payable on the Optional Redemption Date at the applicable Optional Redemption Price, and, unless there is a default in the payment of the applicable Optional Redemption Price,
interest on such Notes shall cease to accrue on and after such Optional Redemption Date. Upon presentation and surrender of such Notes to the Company in accordance with the notice given pursuant to Section 4(a)(ii), such Notes shall be paid and
redeemed at the applicable Optional Redemption Price on the Optional Redemption Date. 
 (iv) Upon surrender of a Note that is redeemed in
part pursuant to Section 4(a)(i) the Company shall execute for the Holder (at the Company’s expense) a new Note (in a form substantially similar to the form of this Note with appropriate notations for the date of issuance and initial
principal amount) equal in principal balance to the unredeemed portion of the Note surrendered; provided, that the denomination of such Note does not and will not fall below $100,000. 

(v) All Notes that are redeemed pursuant to Section 4(a) will be surrendered to the Issuer for cancellation and may not be reissued or
resold. 
 (b) Mandatory Redemption. 

(i) (A) Cash Flow Sweep Mandatory Redemption. In the event that the Adjusted Consolidated Free Cash Flow for any Fiscal Year is greater
than $100,000, then the Company shall use 50% of such Adjusted Consolidated Free Cash Flow for such Fiscal Year to redeem the Notes, at a redemption price equal to the principal amount of such Notes, plus accrued and unpaid interest thereon through
the Mandatory Redemption Date (such redemption, the “Cash Flow Sweep Mandatory Redemption”); provided that in the event that the Adjusted Consolidated Free Cash Flow for any such Fiscal Year is greater than $50,000,000, then
the Company shall use 75% of such Adjusted Consolidated Free Cash Flow for such Fiscal Year to redeem the Notes at a redemption price equal to the principal amount of such Notes, plus accrued and unpaid interest thereon through the Mandatory
Redemption Date; provided further, that in the event that the Company is required to make any payment of principal or interest on any Loans pursuant to Sections 4(a) of the Facility in respect of such Fiscal Year, such amounts so used to make
such payments pursuant to Sections 4(a) of the Facility shall be deducted from the amounts that the Company is otherwise required to use pursuant to this Section 4(b)(i)(A) to redeem the Notes in respect of such Fiscal Year (but not, for the
avoidance of doubt, in respect of any subsequent Fiscal Year). The amount of Adjusted Consolidated Free Cash Flow to be used to redeem the Notes pursuant to this Section 4(b)(i)(A) is referred to herein as the “Excess Consolidated Free
Cash Flow”. Notwithstanding anything to the contrary in this Note, the amount of any Cash Flow Sweep Mandatory Redemption pursuant to this Section 4(b)(i)(A) in respect of any Fiscal Year shall be payable on the applicable Mandatory
Redemption Date only to the extent that such Cash Flow Sweep Mandatory Redemption, if deducted from the calculation of the Cash Flow Sweep Pro Forma Cash Balance as of the end of such Fiscal Year would not cause such Cash Flow Sweep Pro Forma Cash
Balance to be less than $10 million (or $15 million following the Fiscal Year in which the Indebtedness Repayment Condition has been satisfied but in no event prior to October 1, 2015). 

  
 29 








 (B) Unpaid EACFCF Mandatory Redemption. The amount of any such Excess Adjusted
Consolidated Free Cash Flow that is not payable as of any Mandatory Redemption Date under Section 4(b)(i)(A) as a result of the application of the last sentence of Section 4(b)(i)(A) shall continue to be due and owing (such amount, the
“Unpaid EACFCF”), and the Company shall be obligated to mandatorily redeem the Notes (or portion thereof) on each Mandatory Redemption Date occurring thereafter (until all Unpaid EACFCF shall have been redeemed in full) at a
redemption price equal to such Unpaid EACFCF (or portion thereof) only to the extent that such redemption, if deducted from the calculation of the Cash Flow Sweep Pro Forma Cash Balance as of the end of the applicable Fiscal Year (and after giving
effect to any Cash Flow Sweep Mandatory Redemption payable pursuant to Section 4(b)(i)(A) on such Mandatory Redemption Date) would not cause such Cash Flow Sweep Pro Forma Cash Balance to be less than $10 million (or $15 million following the
Fiscal Year in which the Indebtedness Repayment Condition has been satisfied but in no event prior to October 1, 2015) (such redemption, an “Unpaid EACFCF Mandatory Redemption”). 

(ii) Extraordinary Cash Proceeds Mandatory Redemption. In the event that the Company or any of its Subsidiaries receives any cash or
Cash Equivalents (x) from any third party in connection with the license, distribution or sale of any of the Company’s or any of its Subsidiaries’ products (including if such products are combined or are proposed to be combined with
proprietary technology or products of any other Person), including without limitation, lump-sum payments such as milestone payments, upfront payments or payments made in consideration of reduction of royalty rates (but excluding any such lump-sum
payments from any third party in connection with the license, distribution or sale of the Designated Products and the direct sale by the Company or any of its Subsidiaries of its products (including the Designated Products) to customers or royalty
payments based solely on the percentage of product sales or comparable metrics, in each case in the ordinary course of business of the Company or its Subsidiaries), or (y) outside of the ordinary course of business, but only to the extent
unrelated to the sale, license or distribution of the Designated Products (any such cash or Cash Equivalents described in clause (x) and/or (y) of this Section 4(b)(ii), the “Extraordinary Cash Proceeds”), then the
Company shall use 50% of any such Extraordinary Cash Proceeds to: (A) first, redeem Reimbursement Notes in accordance with Section 4 of the Reimbursement Notes, (B) second, if after giving effect to clause (A) in this
Section 4(b)(ii), the Reimbursement Notes have been redeemed in full, reduce the amount outstanding under the Facility in accordance with Section 4(b) of the Facility, (C) third, if, after giving effect to clause (B) in this
Section 4(b)(ii), the amount outstanding under the Facility, including any Loan outstanding under Section 3(c) of the Facility, has been reduced to zero and there are still Borrowings available to be drawn under Section 2(a) of the
Facility, reduce the future amount of the Commitments under the Facility in accordance with Section 4(b) of the Facility, (D) fourth, if, after giving effect to clause (C) in this Section 4(b)(ii), the amount of the Commitment
has been reduced to zero, redeem the Notes (or portion thereof) at a redemption price equal to the principal amount of such Notes, plus accrued and unpaid interest thereon through the Mandatory Redemption Date (such redemption pursuant to this
subclause (D), the “Extraordinary Cash Proceeds Mandatory Redemption”) and (E) fifth, if after giving effect to clause (D) in this Section 4(b)(ii), the Notes have been redeemed in full, redeem the Bridge Notes in
accordance with Section 4(a) of the Bridge Notes. 

  
 30 








 (iii) Cash Royalty Mandatory Redemption. In the event that (A) any Royalty becomes
due under the Royalty Agreement and is payable in cash in accordance with the terms of the Royalty Agreement, (B) on the date such Royalty becomes due under the Royalty Agreement, no principal or interest is outstanding under the Facility, and
(C) the Royalty rate has been reduced to five percent (5%) in accordance with Section 2.1 and 2.2 of the Royalty Agreement, then the Company shall redeem the Notes (or portion thereof) on the applicable Mandatory Redemption Date at a
redemption price equal to the aggregate amount of such Royalty that has become due and payable pursuant to the Royalty Agreement (such redemption, a “Cash Royalty Mandatory Redemption”), solely to the extent that the cash used for
such Cash Royalty Mandatory Redemption, if deducted from the calculation of the Cash Royalty Pro Forma Cash Balance as of the end of such Fiscal Year or Fiscal Quarter, as applicable, would not cause such Cash Royalty Pro Forma Cash Balance to be
less than $10 million (or $15 million following the Fiscal Quarter in which the Indebtedness Repayment Condition has been satisfied but in no event prior to October 1, 2015). 

(iv) In the case of any Cash Flow Sweep Mandatory Redemption, Unpaid EACFCF Mandatory Redemption, Extraordinary Cash Proceeds Mandatory
Redemption or Cash Royalty Mandatory Redemption (any of such redemptions, a “Mandatory Redemption”) in part, the principal balance of the Notes to be redeemed pursuant to such Mandatory Redemption shall be allocated among all of the
Notes at the time outstanding in proportion, as nearly as practicable, to the respective unpaid balances thereof. The Company shall apply the redemption price pursuant to any Mandatory Redemption (the “Mandatory Redemption Price”),
first, to pay accrued and unpaid interest on the Notes, if any, then to redeem the principal amount of the Notes or any portion thereof. 

(v) Written notice in respect of any Cash Flow Sweep Mandatory Redemption or Unpaid EACFCF Mandatory Redemption shall be given by the Company
to the Holder pursuant to Section 11 within ten (10) days of the end of such Fiscal Year. Written notice in respect of any Extraordinary Cash Proceeds Mandatory Redemption or Cash Royalty Mandatory Redemption shall be given by the Company
to the Holder pursuant to Section 11 at least twenty (20) days before the applicable Mandatory Redemption Date. Each such notice shall state: (A) the Mandatory Redemption Price and Mandatory Redemption Date; (B) in the case of a
Mandatory Redemption of the Notes in part, the portion of the outstanding balance of the Notes that is expected to be redeemed and the aggregate balance of Notes to be outstanding after such partial Mandatory Redemption; (C) that Notes to be
redeemed in whole must be surrendered (which action may be taken by any Holder or its authorized agent) to the Company to collect the Mandatory Redemption Price for such Notes, and specifying the procedures for such surrender, and (D) that,
unless the Company fails to pay the Mandatory Redemption Price, interest on Notes (or the portion thereof) called for Mandatory Redemption shall cease to accrue after the Mandatory Redemption Date. In the case of any Cash Flow Sweep Mandatory
Redemption or Unpaid EACFCF Mandatory Redemption, such notice shall also include a certificate of the Chief Financial Officer of the Company certifying the amount of the Excess Adjusted Consolidated Free Cash Flow and setting out in detail a
calculation thereof. 

  
 31 








 (vi) Notes called for redemption pursuant to Section 4(b) shall become due and payable on
the Mandatory Redemption Date at the applicable Mandatory Redemption Price, and, unless there is a default in the payment of the applicable Mandatory Redemption Price, interest on such Notes shall cease to accrue on and after such Mandatory
Redemption Date. Upon presentation and surrender of such Notes to the Company in accordance with the notice pursuant to Section 4(b)(v), such Notes shall be paid and redeemed at the applicable Mandatory Redemption Price on the Mandatory
Redemption Date. Upon surrender of a Note that is redeemed in part pursuant to Section 4(b), the Company shall execute for the Holder (at the Company’s expense) a new Note (in a form substantially similar to the form of this Note with
appropriate notations for the date of issuance and initial principal amount) equal in principal balance to the unredeemed portion of the Note surrendered. 

(vii) All Notes that are redeemed pursuant to Section 4(b) will be surrendered to the Company for cancellation and may not be reissued or
resold. 
 (viii) Notwithstanding anything to the contrary in this Section 4(b), until the applicable Mandatory Redemption Price is
paid, in full, the Holder may convert all or any part of the outstanding principal amount of this Note, plus accrued interest thereof through the Conversion Date, into a number of Conversion Shares in accordance with Section 3 hereof. 

5. Ranking. This Note shall be senior Indebtedness of the Company, ranking senior to all other Indebtedness and future Indebtedness of
the Company in all respects, including in right of payment in full in cash. 
 6. Representations and Warranties of the Company. The
Company hereby represents and warrants to the Holder, as of the date hereof and each other date required to be made hereunder or under the other Transaction Documents (except to the extent such representations and warranties expressly relate only to
an earlier date, in which case such representations and warranties shall be correct and accurate in all material respects on and as of such earlier date), the following:

(b) The execution, delivery and performance by the Company of this Note and the other Transaction Documents, and its obligations hereunder and
thereunder, have been duly authorized and have been approved by the board of directors of the Company upon the recommendation of the Special Committee and do not and will not constitute a breach or violation, or constitute a default under, the
organizational documents of the Company; and this Note and each other Transaction Document to be executed by the Company will constitute the valid and legally binding obligation of the Company, enforceable against it in accordance with its terms,

 32 








 (c) The execution, delivery and performance by the Company of the Loan Documents do not, and the
performance by it of its obligations contemplated thereunder will not, (i) violate or contravene any provision of the Company’s articles of incorporation, bylaws or similar organizational documents; (ii) except as set forth on
Schedule 6(c)(ii), constitute or result in a breach or violation of, or a default under, the acceleration of any obligations of, or the creation of any Lien on the assets of, the Company or any of its Subsidiaries (with or without notice,
lapse of time or both) pursuant to any contract that is binding upon the Company or any of its Subsidiaries, or any change in the rights or obligations of any party under any of such contracts; (iii) except pursuant to the Loan Documents, and
except as set forth on Schedule 6(c)(iii), require the Company or any of its Subsidiaries to obtain the consent, waiver, authorization or approval of any person which has not already been obtained; or (iv) violate, contravene or conflict

 33 








 (h) Each of the Company and its Subsidiaries has good and marketable title to, or leasehold
interest in, all real property and other property and assets owned by it, free and clear of all Liens or other encumbrances securing Indebtedness (other than Permitted Liens), and, subject to Section 7(p), its obligations under both this Note
and the other Loan Documents rank senior to all other existing Indebtedness and future Indebtedness of the Company in all respects, including in right of payment in full in cash.

referred to in this Section 7(j) shall be applied by the Holder promptly to reduce the outstanding amount of the Obligations then due and payable. 

Without limiting the obligations of the Company under the foregoing provisions of this Section, in the event the Company shall fail to
maintain in full force and effect insurance as required by the foregoing provisions of this Section, then the Holder may, but shall have no obligation so to do, procure insurance covering the interests of the Holder in such amounts and against such

Company shall acquire any item of Non-Domestic Intellectual Property, but in no event later than the date twenty Business Days thereafter, the Company shall take all actions necessary or advisable to perfect to the maximum extent permitted or

such failure occurs, (B) such failure to maintain a Perfected Lien in such item of Collateral shall not constitute an Event of Default if such failure results solely from any action or failure to act on the part of the Holder (following notice
thereof from the Company) to maintain such Perfected Lien and which action or failure to act contravenes the provisions of this Note, the other Loan Documents or applicable law, and (C) notwithstanding anything herein or in any Loan Document to
