    CONVERSION
OF DEBENTURE

     

    SECTION
3.1 Conversion; Conversion
Price; Valuation Event.

     

    At the
option of the Holder, this Debenture may be converted, either in whole or in
part, up to the full Principal Amount hereof into Common Shares (calculated as
to each such conversion to the nearest 1/100th of a share), at any time and from
time to time on any Business Day, subject to compliance with Section 3.2. The
number of Common Shares into which this Debenture may be converted is equal to
the dollar amount of the Debenture being converted divided by the Conversion
Price. The “Conversion
Price” shall be equal to the lesser of (i) $0.50, or (ii) 80% of the
average of the 3 lowest Volume Weighted Average Prices during the 20 Trading
Days prior to Holder’s election to convert (the percentage figure being a “Discount Multiplier”). The
Company reserves the right to increase the number of Trading Days in clause (ii)
above, as it deems appropriate.

     

    If the
Holder elects to convert a portion of the Debenture and, on the day that the
election is made, the Volume Weighted Average Price per share of the Company’s
Common Stock is below $0.07, the Company shall have the right to prepay that
portion of the Debenture that Holder elected to convert, plus any accrued and
unpaid interest, at 100% of such amount. In the event that the Company elects to
prepay that portion of the Debenture, Holder shall have the right to withdraw
its Conversion Notice.

     

    SECTION
3.2 Exercise of Conversion
Privilege.  (i) Conversion of this Debenture may be exercised
on any Business Day by the Holder by telecopying an executed and completed
Conversion Notice to the Company.  Each date on which a Conversion
Notice is telecopied to the Company in accordance with the provisions of this
Section 3.2 shall constitute a Conversion Date.  The Company shall
convert this Debenture and issue the Common Stock Issued at Conversion in the
manner provided below in this Section 3.2, and all voting and other rights
associated with the beneficial ownership of the Common Stock Issued at
Conversion shall vest with the Holder, effective as of the Conversion Date at
the time specified in the Conversion Notice.  The Conversion Notice
also shall state the name or names (with addresses) of the persons who are to
become the holders of the Common Stock Issued at Conversion in connection with
such conversion. As promptly as practicable after the receipt of the Conversion
Notice as aforesaid, but in any event not more than two (2) Business Days after
the Company’s receipt of such Conversion Notice, the Company shall (a) issue the
Common Stock Issued at Conversion in accordance with the provisions of this
Article 3 and (b) cause to be mailed for delivery by overnight courier (x) a
certificate or certificate(s) representing the number of Common Shares to which
the Holder is entitled by virtue of such conversion and (y) cash, as provided in
Section 3.3, in respect of any fraction of a Common Share deliverable upon such
conversion.  Such conversion shall be deemed to have been effected at
the time at which the Conversion Notice indicates, and at such time the rights
of the Holder of this Debenture, as such (except if and to the extent that any
Principal Amount thereof remains unconverted), shall cease and the Person and
Persons in whose name or names the Common Stock Issued at Conversion shall be
issuable shall be deemed to have become the holder or holders of record of the
Common Shares represented thereby, and all voting and other rights associated
with the beneficial ownership of such Common Shares shall at such time vest with
such Person or Persons.  The Conversion Notice shall constitute a
contract between the Holder and the Company, whereby the Holder shall be deemed
to subscribe for the number of Common Shares which it will be entitled to
receive upon such conversion and, in payment and satisfaction of such
subscription (and for any cash adjustment to which it is entitled pursuant to
Section 3.4), to surrender this Debenture and to release the Company from all
liability thereon (except if and to the extent that any Principal Amount thereof
remains unconverted).  No cash payment aggregating less than $1.00
shall be required to be given unless specifically requested by the
Holder.

     

    (ii) If, at
any time after the date of this Debenture, (a) the Company challenges, disputes
or denies the right of the Holder hereof to effect the conversion of this
Debenture into Common Shares or otherwise dishonors or rejects any Conversion
Notice delivered in accordance with this Section 3.2 or (b) any third party who
is not and has never been an Affiliate of the Holder commences any lawsuit or
legal proceeding or otherwise asserts any claim before any court or public or
governmental authority which seeks to challenge, deny, enjoin, limit, modify,
delay or dispute the right of the Holder hereof to effect the conversion of this
Debenture into Common Shares, then the Holder shall have the right, but not the
obligation, by written notice to the Company, to require the Company to promptly
redeem this Debenture for cash at one hundred percent (100%) of the Principal
Amount thereof, together with all accrued and unpaid interest thereon to the
date of redemption.  Under any of the circumstances set forth above,
the Company shall be responsible for the payment of all costs and expenses of
the Holder, including reasonable legal fees and expenses, as and when incurred
in defending itself in any such action or pursuing its rights hereunder (in
addition to any other rights of the Holder).

     

    (iii) The
Holder shall be entitled to exercise its conversion privilege notwithstanding
the commencement of any case under the Bankruptcy Code.  In the event
the Company is a debtor under the Bankruptcy Code, the Company hereby waives to
the fullest extent permitted any rights to relief it may have under 11 U.S.C. §
362 in respect of the Holder’s conversion privilege.  The Company
hereby waives to the fullest extent permitted any rights to relief it may have
under 11 U.S.C. § 362 in respect of the conversion of this
Debenture.  The Company agrees, without cost or expense to the Holder,
to take or consent to any and all action necessary to effectuate relief under 11
U.S.C. § 362.

     

    SECTION
3.3 Fractional
Shares.  No fractional Common Shares or scrip representing
fractional Common Shares shall be delivered upon conversion of this
Debenture.  Instead of any fractional Common Shares which otherwise
would be delivered upon conversion of this Debenture, the Company shall pay a
cash adjustment in respect of such fraction in an amount equal to the same
fraction multiplied by the Current Market Price on the Conversion
Date.  No cash payment of less than $1.00 shall be required to be
given unless specifically requested by the Holder.

     

     

    
      
         

      

      
         

        
          

        

      

      
         

      

    

     

    SECTION
3.4 Adjustments.  The
Conversion Price and the number of shares deliverable upon conversion of this
Debenture are subject to adjustment from time to time as follows:

     

    (i) Reclassification,
Etc.  In case the Company shall reorganize its capital,
reclassify its capital stock, consolidate or merge with or into another Person
(where the Company is not the survivor or where there is a change in or
distribution with respect to the Common Stock of the Company), sell, convey,
transfer or otherwise dispose of all or substantially all its property, assets
or business to another Person, or effectuate a transaction or series of related
transactions in which more than fifty percent (50%) of the voting power of the
Company is disposed of (each, a “Fundamental Corporate
Change”) and, pursuant to the terms of such Fundamental Corporate Change,
shares of common stock of the successor or acquiring corporation, or any cash,
shares of stock or other securities or property of any nature whatsoever
(including warrants or other subscription or purchase rights) in addition to or
in lieu of common stock of the successor or acquiring corporation (“Other Property”) are to be
received by or distributed to the holders of Common Stock of the Company, then
the Holder of this Debenture shall have the right thereafter, at its sole
option, to (x) require the Company to prepay this Debenture for cash at one
hundred percent (100%) of the Principal Amount thereof, together with all
accrued and unpaid interest thereon to the date of prepayment, (y) receive
the number of shares of common stock of the successor or acquiring corporation
or of the Company, if it is the surviving corporation, and Other Property as is
receivable upon or as a result of such Fundamental
Corporate Change by a holder of the number of shares of Common Stock into which
the outstanding portion of this Debenture may be converted at the Conversion
Price applicable immediately prior to such Fundamental Corporate Change, or
(z) require the Company, or such successor, resulting or purchasing
corporation, as the case may be, to, without benefit of any additional
consideration therefor, execute and deliver to the Holder a debenture with
substantial identical rights, privileges, powers, restrictions and other terms
as this Debenture in an amount equal to the amount outstanding under this
Debenture immediately prior to such Fundamental Corporate Change.  For
purposes hereof, “common stock
of the successor or acquiring corporation” shall include stock of such
corporation of any class which is not preferred as to dividends or assets over
any other class of stock of such corporation and which is not subject to
prepayment and shall also include any evidences of indebtedness, shares of stock
or other securities which are convertible into or exchangeable for any such
stock, either immediately or upon the arrival of a specified date or the
happening of a specified event and any warrants or other rights to subscribe for
or purchase any such stock.  The foregoing provisions shall similarly
apply to successive Fundamental Corporate Changes.

     

    SECTION
3.5 Certain Conversion
Limits.

     

    The
Company shall not effect any conversion of this Debenture, and a Holder shall
not have the right to convert any portion of this Debenture, to the extent that
after giving effect to the conversion, as set forth on the applicable Conversion
Notice, such Holder (together with such Holder’s Affiliates, and any other
person or entity acting as a group together with such Holder or any of such
Holder’s Affiliates) would beneficially own in excess of the Beneficial
Ownership Limitation (as defined below).  For purposes of the
foregoing sentence, the number of shares of Common Stock beneficially owned by
such Holder and its Affiliates shall include the number of shares of Common
Stock issuable upon conversion of this Debenture with respect to which such
determination is being made, but shall exclude the number of shares of Common
Stock which are issuable upon (A) conversion of the remaining, unconverted
principal amount of this Debenture beneficially owned by such Holder or any of
its Affiliates and (B) exercise or conversion of the unexercised or unconverted
portion of any other securities of the Company subject to a limitation on
conversion or exercise analogous to the limitation contained herein (including,
without limitation, any other Debentures or warrants to purchase shares of the
Company’s Common Stock) beneficially owned by such Holder or any of its
Affiliates.  Except as set forth in the preceding sentence, for
purposes of this Section 3.5, beneficial ownership shall be calculated in
accordance with Section 13(d) of the Exchange Act and the rules and regulations
promulgated thereunder.  To the extent that the limitation contained
in this Section 3.5 applies, the determination of whether this Debenture is
convertible (in relation to other securities owned by such Holder together with
any Affiliates) and of which principal amount of this Debenture is convertible
shall be in the sole discretion of such Holder, and the submission of a
Conversion Notice shall be deemed to be such Holder’s determination of whether
this Debenture may be converted (in relation to other securities owned by such
Holder together with any Affiliates) and which principal amount of this
Debenture is convertible, in each case subject to such aggregate percentage
limitations.  To ensure compliance with this restriction, each Holder
will be deemed to represent to the Company each time it delivers a Conversion
Notice that such Conversion Notice has not violated the restrictions set forth
in this paragraph and the Company shall have no obligation to verify or confirm
the accuracy of such determination.  In addition, a determination as
to any group status as contemplated above shall be determined in accordance with
Section 13(d) of the Exchange Act and the rules and regulations promulgated
thereunder.  For purposes of this Section 3.5, in determining the
number of outstanding shares of Common Stock, a Holder may rely on the number of
outstanding shares of Common Stock provided to the Holder in writing by the
Company after Holder makes such request or in the event that the Company files,
any of the following with the Securities and Exchange Commission, the most
recent of the following: (A) the Company's most recent Form 10-QSB or Form
10-KSB, as the case may be, (B) a more recent public announcement by the
Company; or (C) a more recent notice by the Company or the Company’s transfer
agent setting forth the number of shares of Common Stock
outstanding.  Upon the written or oral request of a Holder, the
Company shall within two Trading Days confirm orally and in writing to such
Holder the number of shares of Common Stock then outstanding on the records of
the Company as of the date of the request.  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
Debenture, by such Holder or its Affiliates since the date as of which such
number of outstanding shares of Common Stock was reported.  The “Beneficial Ownership
Limitation” shall be 4.99% of the number of shares of the Common Stock
outstanding immediately after giving effect to the issuance of shares of Common
Stock issuable upon conversion of this Debenture held by the
Holder.  The Beneficial Ownership Limitation provisions of this
Section 3.5 may be waived by such Holder, at the election of such Holder, upon
not less than 61 days’ prior notice to the Company, to, at the sole discretion
of the Holder, either change the Beneficial Ownership Limitation to (i) 9.99% of
the number of shares of the Common Stock outstanding immediately after giving
effect to the issuance of shares of Common Stock upon conversion of the
Debenture held by the Holder and the provisions of this Section 3.5 shall
continue to apply, or (ii) remove any Beneficial Ownership Limitation under this
Debenture.  The provisions of this paragraph shall be construed and
implemented in a manner otherwise than in strict conformity with the terms of
this Section 3.5 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.  If any court of competent
jurisdiction shall determine that the foregoing limitation is ineffective to
prevent a Holder from being deemed the beneficial owner of more than 9.99% of
the then outstanding shares of Common Stock, then the Company shall prepay such
portion of this Debenture as shall cause such Holder not to be deemed the
beneficial owner of more than 9.99% of the then outstanding shares of Common
Stock.  Upon such determination by a court of competent jurisdiction,
the Holder shall have no interest in or rights under such portion of the
Debenture.  Any and all interest paid on or prior to the date of such
determination shall be deemed interest paid on the remaining portion of this
Debenture held by the Holder.  Such prepayment shall be for cash at a
prepayment price of one hundred percent (100%) of the Principal Amount thereof,
together with all accrued and unpaid interest thereon to the date of
prepayment.  The limitations contained in this paragraph shall apply
to a successor holder of this Debenture.

     

    SECTION
3.6 Surrender of
Debentures.  Upon any redemption of this Debenture pursuant to
Sections 3.2, 3.5 or 6.2, or upon maturity pursuant to Section 2.4, the Holder

hereof or to declare an Event of Default.

require opinions of counsel for transactions involving transfers to Affiliates
of the Holder or pursuant to Rule 144 promulgated by the SEC under the
Securities Act, except in unusual circumstances, or (ii) a registration
statement relating to this Debenture or such shares has been filed by the
Company and declared effective by the SEC.

     

    Each
certificate for shares of Common Stock deliverable hereunder shall bear a legend
as follows unless and until such securities have been sold pursuant to an
effective registration statement under the Securities Act:

     

    “The
securities represented by this certificate have not been registered under the
Securities Act of 1933, as amended (the “Securities Act”).  The
securities may not be offered for sale, sold or otherwise transferred except (i)
pursuant to an effective registration statement under the Securities Act or (ii)
pursuant to an exemption from registration under the Securities Act in respect
of which the issuer of this certificate has received an opinion of counsel
reasonably satisfactory to the issuer of this certificate to such
effect.  Copies of the agreement covering both the purchase of the
securities and restrictions on their transfer may be obtained at no cost by
written request made by the holder of record of this certificate to the

    SECTION
6.2 Acceleration of Maturity;
Rescission and Annulment.  If an Event of Default occurs and is
continuing, then and in every such case the Holder may, in Holder’s sole and
absolute discretion, by a notice in writing to the Company, rescind any
outstanding Conversion Notice and declare that any or all amounts owing or
otherwise outstanding under this Debenture are immediately due and payable and
upon any such declaration this Debenture or such portion thereof, as applicable,
shall become immediately due and payable in cash at a price of one hundred
percent (100%) of the Principal Amount thereof, together with all accrued and
unpaid interest thereon to the date of payment; provided, however, in the case
of any Event of Default described in clauses (iii), (iv), (v) or (vii) of
Section 6.1, all amounts owing or otherwise outstanding under this Debenture
automatically shall become immediately due and payable without the necessity of
any notice or declaration as aforesaid.  In the event that the Company
is obligated to pay any amount to the Holder in connection with an acceleration
of the maturity of this Debenture as set forth herein, the Company shall first
apply against such amount an amount equal to the outstanding amount owed by the
Holder to the Company under the Promissory Note, if any, and the amount
otherwise owed by the Company to the Holder in connection with an acceleration
of the maturity of this Debenture shall be reduced by the outstanding amount
owed by the Holder to the Company under the Promissory Note, with the Promissory
Note deemed paid by Holder to the extent of and with respect to such amount, and
if the amount due from the Company to the Holder in connection with an
acceleration of the maturity of this Debenture is equal to or greater than the
outstanding amount owed under the Promissory Note, the Company shall cancel and
deem the Promissory Note as paid in full in connection with the application of
the amount owed by the Holder to the Company under Promissory Note against the
amount otherwise owed by the Company to the Holder hereunder.  The
Company shall immediately pay in cash to the Holder any remaining amount owed by
the Company to the Holder in connection with the acceleration of the maturity of
this Debenture as described herein, after the application of the outstanding
amount owed under the Promissory Note, if any, to such obligation.

     

    SECTION
6.3 Late Payment
Penalty.  If any portion of the principal of or interest on
this Debenture shall not be paid within ten (10) days of when it is due, the
Discount Multiplier under this Debenture shall decrease by one percentage point
(1%) for each period of ten (10) Business Days that any portion of such amount
remains unpaid by the Company for all conversions of this Debenture
thereafter.

     

    SECTION
6.4 Maximum Interest
Rate.  Notwithstanding anything herein to the contrary, if at
any time the applicable interest rate as provided for herein shall exceed the
maximum lawful rate which may be contracted for, charged, taken or received by
the Holder in accordance with any applicable law (the “Maximum Rate”), the rate of
interest applicable to this Debenture shall be limited to the Maximum
Rate.  To the greatest extent permitted under applicable law, the
Company hereby waives and agrees not to allege or claim that any provisions of
this Debenture could give rise to or result in any actual or potential violation
of any applicable usury laws.

     

    SECTION
6.5 Remedies Not
Waived.  No course of dealing between the Company and the
Holder or any delay in exercising any rights hereunder shall operate as a waiver
by the Holder.

     

    SECTION
6.6 Remedies. The
Company acknowledges that a breach by it of its obligations hereunder will cause
irreparable harm to the Holder, by vitiating the intent and purpose of the
transaction contemplated hereby. Accordingly, the Company acknowledges that the
remedy at law for a breach of its obligations under this Debenture will be
inadequate and agrees, in the event of a breach or threatened breach by the
Company of the provisions of this Debenture, that the Holder shall be entitled
to all other available remedies at law or in equity, and in addition to the
penalties assessable herein, to an injunction or injunctions restraining,
preventing or curing any breach of this Debenture and to enforce specifically
the terms and provisions thereof, without the necessity of showing economic loss
and without any bond or other security being required.

     

    SECTION
6.7 Payment of
Certain Amounts. Whenever pursuant to this Debenture the Company is
required to pay an amount in excess of the Principal Amount plus accrued and
unpaid interest, the Company and the Holder agree that the actual damages to the
Holder from the receipt of cash payment on this Debenture may be difficult to
determine and the amount to be so paid by the Company represents stipulated
damages and not a penalty and is intended to compensate the Holder in part for
loss of the opportunity to convert this Debenture and to earn a return from the
sale of shares of Common Stock acquired upon conversion of this Debenture at a
price in excess of that price paid for such shares pursuant to this Debenture.
The Company and the Holder hereby agree that such amount of stipulated damages
is not disproportionate to the possible loss to the Holder from the receipt of a
cash payment without the opportunity to convert this Debenture into shares of
Common Stock.

     

    SECTION
6.8 Filing of
Form 8-K. On or before the fourth Business Day following the date
hereof, the Company shall file a Current Report on Form 8-K describing the terms
of the transactions contemplated by the Documents (as defined in the Securities
Purchase Agreement), as required by the terms of the Securities Purchase
Agreement, in the form required by the Exchange Act and attaching the material
Documents (including, without limitation, the Securities Purchase Agreement and
this Debenture) as exhibits to such filing (the “8-K Filing”).  In
the event that the Company does not file the 8-K Filing within four Business
Days following the date hereof, the Discount Multiplier under this Debenture
shall decrease by one percentage point (1%) for each period of five Business
Days that the 8-K Filing is not filed by the Company following the date hereof
for all conversions of this Debenture thereafter.

    INTEREST
RATE ADJUSTMENT

     

    SECTION
7.1 Interest Rate
Adjustment.  In the event that the Common Stock shall trade on
the Trading Market at a price per share that is $0.01 per share or lower at any
time during the six month period commencing on the date hereof and ending on the
six month anniversary of the date hereof (as adjusted for any stock splits,
stock dividends, combinations, subdivisions, recapitalizations or the like),
then (i) the Interest Rate shall immediately be increased to Nine and
Three-Quarters Percent (9 3⁄4 %) and shall remain at such level for the duration
of this Debenture; and (ii) the Company shall, within three Business Days of the
written request of the Holder prepay to the Holder the amount of interest that
would be otherwise paid under this Debenture from the date of such written
request through the Maturity Date (such amount referred to herein as the “Interest
Prepayment”).  In the event that after the payment by the
Company of the Interest Prepayment all or any of the Principal Amount of this
Debenture is converted by Holder or redeemed pursuant to the terms of this
Debenture prior to the Maturity Date, then the Holder shall repay the
corresponding pro rata portion of the Interest Prepayment equal to the amount of
the Interest Prepayment that is represented by such portion of the Principal
Amount at such time that that is so converted or redeemed (taking into account
both the amount of the Principal Amount so converted or redeemed and the date
upon which such amount is so converted or redeemed).

Indenture”), dated as of November 28, 2007, among Nielsen Business Media Holding Company, a Delaware corporation (the “Guaranteeing Subsidiary”) and affiliate of Nielsen Finance LLC, a Delaware limited liability
company, and Nielsen Finance Co., a Delaware corporation (the “Issuers”), and Law Debenture Trust Company of New York, as trustee (the “Trustee”). 
 W I T N E S S E T H 
 WHEREAS, the Issuers and the Guarantors (as defined in the
Indenture referred to below) have heretofore executed and delivered to the Trustee an indenture, dated as of August 9, 2006, as amended and supplemented from time to time (the “Indenture”), providing for the issuance of an
unlimited aggregate principal amount at maturity of Senior Subordinated Discount Notes due 2016 (the “Notes”); 
 WHEREAS,
the Indenture provides that under certain circumstances the Guaranteeing Subsidiary shall execute and deliver to the Trustee a supplemental indenture pursuant to which the Guaranteeing Subsidiary shall unconditionally guarantee all of the
Issuers’ Obligations under the Notes and the Indenture on the terms and conditions set forth herein and under the Indenture (the “Guarantee”); and 
 WHEREAS, pursuant to Section 9.01 of the Indenture, the Trustee is authorized to execute and deliver this Fourth Supplemental Indenture. 
 NOW THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, the parties
mutually covenant and agree for the equal and ratable benefit of the Holders of the Notes as follows: 
 (1) Capitalized Terms.
Capitalized terms used herein without definition shall have the meanings assigned to them in the Indenture. 
 (2) Agreement to
Guarantee. The Guaranteeing Subsidiary hereby agrees as follows: 
 (a) Along with all Guarantors named in the Indenture,
to jointly and severally unconditionally guarantee to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of the Indenture, the Notes or
the obligations of the Issuers hereunder or thereunder, that: 
 (i) the principal of and interest, premium and Additional
Interest, if any, on the Notes will be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other obligations of
the Issuers to the Holders or the Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and 
  

 (ii) in case of any extension of time of payment or renewal of any Notes or any of such
other obligations, that same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at stated maturity, by acceleration or otherwise. Failing payment when due of any amount so guaranteed
or any performance so guaranteed for whatever reason, the Guarantors and the Guaranteeing Subsidiary shall be jointly and severally obligated to pay the same immediately. This is a guarantee of payment and not a guarantee of collection. 

(b) The obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or the
Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Issuers, any action to enforce the same or any
other circumstance which might otherwise constitute a legal or equitable discharge or defense of a Guarantor. 
 (c) The
following is hereby waived: diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Issuers, any right to require a proceeding first against the Issuers, protest, notice and all
demands whatsoever. 
 (d) The Guarantee shall not be discharged except by complete performance of the obligations contained
in the Notes, the Indenture and this Fourth Supplemental Indenture, and the Guaranteeing Subsidiary accepts all obligations of a Guarantor under the Indenture. 
 (e) If any Holder or the Trustee is required by any court or otherwise to return to the Issuers, the Guarantors (including the
Guaranteeing Subsidiary), or any custodian, trustee, liquidator or other similar official acting in relation to either the Issuers or the Guarantors, any amount paid either to the Trustee or such Holder, the Guarantee, to the extent theretofore
discharged, shall be reinstated in full force and effect. 
 (f) The Guaranteeing Subsidiary shall not be entitled to any
right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. 
 (g) As between the Guaranteeing Subsidiary, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6
of the Indenture for the purposes of the Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any declaration of acceleration
of such obligations as provided in Article 6 of the Indenture, such obligations (whether or not due and payable) shall forthwith become due and payable by the Guaranteeing Subsidiary for the purpose of the Guarantee. 
  

 2 

 (h) The Guaranteeing Subsidiary shall have the right to seek contribution from any
non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Guarantee. 
 (i) Pursuant to Section 11.02 of the Indenture, after giving effect to all other contingent and fixed liabilities that are relevant under any applicable Bankruptcy or fraudulent conveyance laws, and after giving effect to any
collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under Article 11 of the Indenture, this new Guarantee shall be limited to the maximum
amount permissible such that the obligations of the Guaranteeing Subsidiary under the Guarantee will not constitute a fraudulent transfer or conveyance. 
 (j) The Guarantee shall remain in full force and effect and continue to be effective should any petition be filed by or against the Issuers for liquidation, reorganization, should the Issuers become insolvent or make
an assignment for the benefit of creditors or should a receiver or trustee be appointed for all or any significant part of the Issuers’ assets, and shall, to the fullest extent permitted by law, continue to be effective or be reinstated, as the
case may be, if at any time payment and performance of the Notes are, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by any obligee on the Notes and the Guarantee, whether as a “voidable
preference”, “fraudulent transfer” or otherwise, all as though such payment or performance had not been made. In the event that any payment or any part thereof, is rescinded, reduced, restored or returned, the Note shall, to the
fullest extent permitted by law, be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned. 
 (k) In case any provision of the Guarantee shall be invalid, illegal or unenforceable, the validity, legality, and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

 (l) The Guarantee shall be a general unsecured senior subordinated obligation of the Guaranteeing Subsidiary, ranking
pari passu with any other future Senior Subordinated Indebtedness of the Guaranteeing Subsidiary, if any. 
 (m) Each
payment to be made by the Guaranteeing Subsidiary in respect of the Guarantee shall be made without set-off, counterclaim, reduction or diminution of any kind or nature. 
 (3) Execution and Delivery. The Guaranteeing Subsidiary agrees that the Guarantee shall remain in full force and effect notwithstanding the absence of the endorsement of any notation of the Guarantee on the
Notes. 
 (4) Merger, Consolidation or Sale of All or Substantially All Assets. 
 (a) Except as otherwise provided in Section 5.01(c) of the Indenture, the Guaranteeing Subsidiary may not consolidate or merge with

transactions, to any Person unless: 
 (i) (A) the Guaranteeing Subsidiary is the surviving corporation or the Person formed

 (B) the Successor Person, if other than the Guaranteeing Subsidiary, expressly assumes
all the obligations of the Guaranteeing Subsidiary under the Indenture and the Guaranteeing Subsidiary’s Guarantee pursuant to supplemental indentures or other documents or instruments in form reasonably satisfactory to the Trustee; 

(C) immediately after such transaction, no Default exists; and 
 (D) the Issuers shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that such
consolidation, merger or transfer and such supplemental indentures, if any, comply with the Indenture; or 
 (ii) the
transaction is made in compliance with Section 4.10 of the Indenture; 
 (b) Subject to certain limitations described in
the Indenture, the Successor Person will succeed to, and be substituted for, the Guaranteeing Subsidiary under the Indenture and the Guaranteeing Subsidiary’s Guarantee. Notwithstanding the foregoing, the Guaranteeing Subsidiary may merge into
or transfer all or part of its properties and assets to another Guarantor or the Issuers. 
 (5) Releases. The Guarantee of the
Guaranteeing Subsidiary shall be automatically and unconditionally released and discharged, and no further action by the Guaranteeing Subsidiary, the Issuers or the Trustee is required for the release of the Guaranteeing Subsidiary’s Guarantee,
upon: 
 (a) (i) any sale, exchange or transfer (by merger or otherwise) of the Capital Stock of the Guaranteeing Subsidiary
(including any sale, exchange or transfer), after which the Guaranteeing Subsidiary is no longer a Restricted Subsidiary or all or substantially all the assets of the Guaranteeing Subsidiary which sale, exchange or transfer is made in compliance
with the applicable provisions of the Indenture; 
 (ii) the release or discharge of the guarantee by the Guaranteeing

Guaranteeing Subsidiary shall have any liability for any obligations of the Issuers or the Guarantors (including the Guaranteeing Subsidiary) under the Notes, any Guarantees, the Indenture or this Fourth Supplemental Indenture or for any claim based
on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting Notes waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes.
