 Each party agrees as follows for the benefit of the other party and for the equal and ratable benefit of the Holders of the Company’s Senior Secured Notes due 2019 (the

 I. DEFINITIONS AND INCORPORATION BY REFERENCE 
  

	1.01	DEFINITIONS. 

 “Accreted Value” means, as of any date (the “Specified Date”), the amount provided below for each $1,000 principal amount at maturity of Notes:

will equal the amount set forth below for such Semi-Annual Accrual Date: 
  

					
	Semi-annual accrual date	  	Accreted value

360-day year of 12 30-day months, and the denominator of which is 180 (or, if the Semi-Annual Accrual Date immediately preceding the Specified Date is the Issue Date, the denominator of which is the number of days from and including the Issue Date

basis points, of the excess, if any, of (a) (i) the redemption price of such Securities at May 9, 2015 (each such redemption price being set forth in Section 3.01), plus (ii) all required interest payments due on such
Securities through May 9, 2015 (excluding accrued but unpaid interest to the Redemption Date); over (b) the outstanding principal amount at maturity of such Securities. 

“Asset Acquisition” means: (i) an Investment by the Company or any of its Restricted Subsidiaries in any other
Person, pursuant to which investment such Person shall become a Restricted Subsidiary of the Company or shall be merged with or into the Company or any of its Restricted Subsidiaries; or (ii) the acquisition, by the Company or any of its
Restricted Subsidiaries, of the assets of any Person (other than a Restricted Subsidiary of the Company) which constitute all or substantially all of the assets of such Person or comprise any division or line of business of such Person or any other

Stock of any Restricted Subsidiary of the Company; or (ii) any other property or assets of the Company or any Restricted Subsidiary of the Company, in each case other than in the ordinary course of business; provided, however, that
“Asset Sale” shall not include (1) a transaction or series of related transactions for which the Company or its Restricted Subsidiaries receive aggregate consideration of less than $500,000; (2) the sale, lease, conveyance,
disposition or other transfer of all or substantially all of the assets of the Company as permitted under Section 5.01; (3) any Permitted Investment or any Restricted Payment permitted under Section 4.11; (4) the

the Paying Agent for the payment of the Accreted Value of, or premium, if any, of the Securities, and shall notify the Trustee of any Default by the Company in making any such payment. While any such Default continues, the Trustee may require a
Paying Agent to pay all money held by it to the Trustee. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent shall have no further liability for such
money. If the Company acts as Paying Agent, it shall segregate and hold as a separate trust fund all money held by it as Paying Agent. 
  

	2.05	SECURITYHOLDER LISTS. 

 The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Securityholders. If the Trustee is not the Registrar, the
Company shall furnish to the Trustee on or before each interest payment date and at such other times as the Trustee may request in writing a list, in such form and as of such date as the Trustee may reasonably require, of the names and addresses of
Securityholders. 
  

	2.06	TRANSFER AND EXCHANGE. 

 Subject to Sections 2.15 and 2.16 hereof, where Securities are presented to the Registrar with a request to register their transfer or to exchange them for an equal
Accreted Value of and premium, if any, on such Securities of other authorized denominations, the Registrar shall register the transfer or make the exchange if its requirements for such transaction are met. To permit registrations of transfer and
exchanges, the Trustee shall authenticate Securities at the Registrar’s request. The Company or the Trustee, as the case may be, shall not be required to register the transfer of or exchange any Security (i) for a period of 15 days
before selecting, pursuant to Section 3.03, Securities to be redeemed or (ii) during a period beginning at the opening of business 15 days before the mailing of a notice of redemption of the Securities selected
for Redemption under Section 3.04 and ending at the close of business on the day of such mailing or (iii) that has been selected for Redemption or for which a Purchase Notice has been delivered, and not withdrawn, in
accordance with this Indenture, except the unredeemed or unrepurchased portion of Securities being redeemed or repurchased in part. 
 No service charge shall be made for any transfer or exchange of Securities, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge that may be
imposed in connection with any transfer or exchange of Securities, other than exchanges pursuant to Sections 2.10 or 11.05, or Article III, not involving any transfer. 

  
 -25-









 Notwithstanding anything to the contrary in the provisions of this Section 2.6,
at all times prior to the Separation Date (i) the registered holder of each Security shall also be the registered holder of the Warrant forming part of such Unit, and (ii) the owner of any beneficial interest in any Security, as reflected
in the book-entry system maintained by the Depositary (or its agent), also shall be the owner of any beneficial interest in the Warrant forming part of such Unit. Accordingly and in furtherance of the foregoing, prior to the Separation Date no
transfer or exchange shall be made with respect to (i) the Holder of any Security, unless a simultaneous and equivalent transfer or exchange is made with respect to the registered holder of each Warrant forming an integral part of such Unit in
accordance with the Warrant Agreement, and the certificates representing such Security (whether a Global Security or a certificated Security) and the certificates representing such Warrants are incorporated into one or more Unit certificate(s)
substantially in the form attached as Exhibit E and (ii) the ownership of any beneficial interest in a Global Security, as reflected in the book-entry system maintained by the Depositary (or its agent), unless a simultaneous and
equivalent transfer or exchange is made with respect to the ownership of any beneficial interest in each Warrant forming an integral part of such Units in accordance with, and as reflected in the book-entry system maintained by the Depositary (or
its agent) of the Warrants under, the Warrant Agreement. 
  

	2.07	REPLACEMENT SECURITIES. 

 If the Holder of a Security claims that the Security has been mutilated, lost, destroyed or wrongfully taken, the Company shall issue and the Trustee shall authenticate a replacement Security upon
surrender to the Trustee of the mutilated Security, or upon delivery to the Trustee of evidence of the loss, destruction or theft of the Security satisfactory to the Trustee and the Company. In the case of a lost, destroyed or wrongfully taken
Security, if required by the Trustee or the Company, an indemnity bond must be provided by the Holder that is reasonably satisfactory to the Trustee and the Company to protect the Company, the Trustee or any Securities Agent from any loss which any
of them may suffer if such Security is replaced. The Trustee may charge for its expenses in replacing a Security. 
 In case any
such mutilated, lost, destroyed or wrongfully taken Security has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, pay such Security when due. 

Every replacement Security is an additional obligation of the Company only as provided in Section 2.08.

  

	2.08	OUTSTANDING SECURITIES. 

 Securities outstanding at any time are all the Securities authenticated by the Trustee except for those cancelled by it, those delivered to it for cancellation and those described in this
Section 2.08 as not outstanding. Except to the extent provided in Section 2.09, a Security does not cease to be outstanding because the Company or one of its Subsidiaries or Affiliates holds the
Security. 
 If a Security is replaced pursuant to Section 2.07, it ceases to be outstanding unless
the Trustee receives proof satisfactory to it, or a court holds, that the replaced Security is held by a protected purchaser. 

If the outstanding principal amount at maturity of any Note is considered paid under Section 4.01 hereof, it ceases to be
outstanding and its Accreted Value ceases to increase. 

  
 -26-









 If the Paying Agent (other than the Company) holds on a Redemption Date, Fundamental Change
Repurchase Date, Asset Sale Repurchase Date or Maturity Date, money sufficient to pay the aggregate applicable redemption price, Fundamental Change Repurchase Price, Asset Sale Repurchase Price or principal amount, as the case may be, with respect
to all Securities to be redeemed, purchased or paid upon Redemption, Repurchase Upon Fundamental Change, Repurchase Upon Asset Sale or maturity, as the case may be, in each case plus, if applicable, accrued and unpaid interest, if any, payable as
herein provided upon Redemption, Repurchase Upon Fundamental Change, Repurchase Upon Asset Sale or maturity, then (unless there shall be a Default in the payment of such aggregate applicable redemption price, Fundamental Change Repurchase Price,
Asset Sale Repurchase Price or principal amount, or of such accrued and unpaid interest), except as otherwise provided herein, on and after such date such Securities shall be deemed to be no longer outstanding, interest on such Securities shall
cease to accrue, the Accreted Value of such Securities shall cease to accrue and such Securities shall be deemed paid whether or not such Securities are delivered to the Paying Agent. Thereafter, all rights of the Holders with respect to such
Securities shall terminate with respect to such Securities, other than the right to receive the applicable redemption price, Fundamental Change Repurchase Price, Asset Sale Repurchase Price or principal amount, as the case may be, plus, if
applicable, such accrued and unpaid interest, in accordance with this Indenture. 
  

	2.09	SECURITIES HELD BY THE COMPANY OR AN
AFFILIATE. 

 In determining whether the Holders of the required aggregate principal amount of
Securities have concurred in any direction, waiver or consent, to the extent required by the TIA, Securities owned by the Company or any of its Subsidiaries or Affiliates shall be considered as though not outstanding, except that, for the purposes
of determining whether a Responsible Officer of the Trustee shall be protected in relying on any such direction, waiver or consent, only Securities which the Trustee knows are so owned shall be so disregarded. Securities so owned which have been
pledged in good faith may be considered to be outstanding for purposes of this Section 2.09 if the pledgee establishes, to the satisfaction of the Trustee, the pledgee’s right so to concur with respect to such
Securities and that the pledgee is not, and is not acting at the direction or on behalf of, the Company, any other obligor on the Securities, an Affiliate of the Company or an affiliate of any such other obligor. In the event of a dispute as to
whether the pledgee has established the foregoing, the Trustee may rely on the advice of counsel or on an Officers’ Certificate. 
  

	2.10	TEMPORARY SECURITIES. 

 Until definitive Securities are ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Securities. Temporary Securities shall be substantially in the form of definitive
Securities but may have variations that the Company considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate definitive Securities in exchange for temporary Securities.
Until so exchanged, each temporary Security shall in all respects be entitled to the same benefits under this Indenture as definitive Securities, and such temporary Security shall be exchangeable for definitive Securities in accordance with the
terms of this Indenture. 
  

	2.11	CANCELLATION. 

 The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar and Paying Agent shall forward to the Trustee any Securities surrendered to them for transfer, exchange or
payment. The Trustee shall promptly cancel all Securities surrendered for transfer, exchange, payment or cancellation in accordance with its customary procedures. The Company may not issue new Securities to replace Securities that it has paid or
delivered to the Trustee for cancellation. 

  
 -27-










	2.12	DEFAULTED INTEREST. 

 If and to the extent the Company defaults in a payment of interest on the Securities, the Company shall pay in cash the defaulted interest in any lawful manner plus, to the extent not prohibited by
applicable statute or case law, interest on such defaulted interest at the rate provided in the Securities (and as set forth in Section 4.01). The Company may pay the defaulted interest (plus interest on such defaulted interest) to the
persons who are Securityholders on a subsequent special record date. The Company shall fix such record date and payment date. At least 15 calendar days before the record date, the Company shall mail to Securityholders (with a copy to the Trustee) a
notice that states the record date, payment date and amount of interest to be paid. 
  

	2.13	CUSIP NUMBERS. 

 The Company in issuing the Securities may use one or more “CUSIP” numbers, and, if so, the Trustee shall use the CUSIP numbers in notices of redemption or exchange as a convenience to Holders;
provided, however, that no representation is hereby deemed to be made by the Trustee as to the correctness or accuracy of the CUSIP numbers printed on the notice or on the Securities; provided further, that reliance may be
placed only on the other identification numbers printed on the Securities, and the effectiveness of any such notice shall not be affected by any defect in, or omission of, such CUSIP numbers. The Company shall promptly notify the Trustee of any
change in the CUSIP numbers. 
  

	2.14	DEPOSIT OF MONEYS. 

 Prior to 11:00 A.M., New York City time, on each interest payment date, Maturity Date, Redemption Date, Asset Sale Repurchase Date or Fundamental Change Repurchase Date, the Company shall have deposited
with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust in accordance with Section 2.04) money, in funds immediately available on such date, sufficient to make cash payments,
if any, due on such interest payment date, Maturity Date, Redemption Date, Asset Sale Repurchase Date or Fundamental Change Repurchase Date, as the case may be, in a timely manner which permits the Paying Agent to remit payment to the Holders on
such interest payment date, Maturity Date, Redemption Date, Asset Sale Repurchase Date or Fundamental Change Repurchase Date, as the case may be. The Paying Agent shall return to the Company, as soon as practicable, any excess money not required for
that purpose. 
  

	2.15	BOOK-ENTRY PROVISIONS FOR GLOBAL SECURITIES. 


(A) The Global Securities initially shall (i) be registered in the name of the Depositary or the nominee of the Depositary,
(ii) be delivered to the Trustee as custodian for the Depositary and (iii) bear legends as set forth in Section 2.17. 
 Members of, or participants in, the Depositary (“Participants”) shall have no rights under this Indenture with respect to any Global Security held on their behalf by the Depositary, or
the Trustee as its custodian, or under the Global Security, and the Depositary may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner of the Global Security for all purposes whatsoever.
Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or impair, as
between the Depositary and Participants, the operation of customary practices governing the exercise of the rights of a Holder of any Security. 

  
 -28-









 (B) Transfers of Global Securities shall be limited to transfers in whole, but not in part,
to the Depositary, its successors or their respective nominees. In addition, Physical Securities shall be transferred to all beneficial owners, as identified by the Depositary, in exchange for their beneficial interests in Global Securities only if
(i) the Depositary notifies the Company that the Depositary is unwilling or unable to continue as depositary for any Global Security (or the Depositary ceases to be a “clearing agency” registered under Section 17A of the Exchange
Act) and a successor Depositary is not appointed by the Company within 90 days of such notice or cessation or (ii) an Event of Default has occurred and is continuing and the Registrar has received a written request from the Depositary to
issue Physical Securities. 
 (C) In connection with the transfer of a Global Security in its entirety to beneficial owners
pursuant to Section 2.15(B), such Global Security shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and the Trustee shall upon written instructions from the Company
authenticate and deliver, to each beneficial owner identified by the Depositary in exchange for its beneficial interest in such Global Security, an equal aggregate principal amount of Physical Securities of authorized denominations. 

(D) Any Physical Security constituting a Restricted Security delivered in exchange for an interest in a Global Security pursuant to
Section 2.15(B) shall, except as otherwise provided by Section 2.16, bear the Private Placement Legend. 
 (E) The Holder of any Global Security may grant proxies and otherwise authorize any Person, including Participants and Persons that may hold interests through Participants, to take any action which a
Holder is entitled to take under this Indenture or the Securities. 
  

	2.16	SPECIAL TRANSFER PROVISIONS. 

 (A) Transfers Pursuant to Regulation S. The following provisions shall apply with respect to the registration of any proposed transfer of a Security that is a Restricted Security
pursuant to Regulation S: 
 (i) The Registrar shall register such proposed transfer if there is delivered to the Registrar
and the Company a certificate substantially in the form of Exhibit C-1 (with such changes as may be reasonably requested by the Company) and, if reasonably requested by the Registrar or the Company in connection with a transfer
that is not to be executed in, on or through the facilities of a “designated offshore securities market” (as defined in Regulation S), a certificate substantially in the form of Exhibit C-2 (with such changes as may
be reasonably requested by the Company) and any legal opinions and other certifications reasonably requested by the Company or the Registrar. 
 (ii) If such Security is not a Regulation S Global Security, then the Company shall issue, and, upon receipt of a Company Order, the Trustee shall authenticate, a Regulation S Global Security
having a principal amount equal to the principal amount to be transferred or, alternatively, the Registrar shall accept the instructions from Participants of the Depositary to increase the principal amount of an existing Regulation S Global
Security by the principal amount to be transferred, and in each case, correspondingly decrease the principal amount of the Security from which the principal amount was transferred. 

  
 -29-









 (B) Transfers to QIBS. The following provisions shall apply with respect to the
registration of any proposed transfer of a Restricted Security (other than pursuant to Regulation S): 
 (i) The Registrar
shall register the transfer of a Restricted Security by a Holder to a QIB if such transfer is being made by a proposed transferor who has provided the Registrar with (a) an appropriately completed certificate of transfer in the form attached to
the Note and (b) a letter substantially in the form set forth in Exhibit D hereto. 
 (ii) If such Security is
not a QIB Global Security, then the Company shall issue, and the Trustee shall authenticate, upon receipt of a Company Order, a QIB Global Security having a principal amount equal to the principal amount to be transferred or, alternatively, the
Registrar shall accept the instructions from Participants of the Depositary to increase the principal amount of an existing QIB Global Security by the principal amount to be transferred, and in each case, correspondingly decrease the principal
amount of the Security from which the principal amount was transferred. 
 (C) Restrictions on Transfer and Exchange of
Global Securities. Notwithstanding any other provisions of this Indenture, but except as provided in Section 2.15(B), a Global Security may not be transferred except as a whole by the Depositary to a nominee of the Depositary or by a
nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. 

(D) Private Placement Legend. Upon the transfer, exchange or replacement of Securities not bearing the Private Placement Legend,
the Registrar shall deliver Securities that do not bear the Private Placement Legend. Upon the transfer, exchange or replacement of Securities bearing the Private Placement Legend, the Registrar shall deliver only Securities that bear the Private
Placement Legend unless there is delivered to the Company and the Trustee an Opinion of Counsel reasonably satisfactory to the Company and the Trustee to the effect that neither such legend nor the related restrictions on transfer are required in
order to maintain compliance with the provisions of the Securities Act. 
 (E) General. By its acceptance of any Security
bearing the Private Placement Legend, each Holder of such a Security acknowledges the restrictions on transfer of such Security set forth in this Indenture and in the Private Placement Legend and agrees that it will transfer such Security only as
provided in this Indenture. 
 The Registrar shall retain copies of all letters, notices and other written communications
received pursuant to Section 2.15 or this Section 2.16. The Company shall have the right to inspect and make copies of all such letters, notices or other written communications at the Company’s expense at any reasonable
time upon the giving of reasonable written notice to the Registrar. 

  
 -30-










	2.17	RESTRICTIVE LEGENDS. 

 Each Global Security and Physical Security that constitutes a Restricted Security shall bear the legend (the “Private Placement Legend”) as set forth in Exhibit B-1 on
the face thereof (1) until after the first anniversary of the later of (i) the Issue Date and (ii) the last date on which the Company or any Affiliate was the owner of such Security (or any predecessor security) (or such shorter
period of time as permitted by Rule 144 under the Securities Act or any successor provision thereunder) (or such longer period of time as may be required under the Securities Act or applicable state securities laws, as set forth in an Opinion
of Counsel, unless otherwise agreed between the Company and the Holder thereof) (such date, the “Resale Restriction Termination Date”); or (2) as otherwise provided in or permitted by
Section 2.16(D). 
 Each Global Security shall bear the legend set forth in
Exhibit B-2. 
 Each Global Security and Physical Security shall bear the legend as set forth in
Exhibit B-3. The Company shall provide notice to the Trustee of any Resale Restriction Termination Date. 

Until the Separation Date, each Global Security and Physical Security shall bear the legend as set forth in Exhibit B-4.

  

	2.18	AUTOMATIC EXCHANGE FROM RESTRICTED GLOBAL NOTE TO
UNRESTRICTED GLOBAL NOTE. 

 On the Resale Restriction Termination
Date, beneficial interests in a Global Security that bears the Private Placement Legend (a “Restricted Global Security”) shall be automatically exchanged (the “Automatic Exchange”) into beneficial interests in a
Global Security not bearing the Private Placement Legend (an “Unrestricted Global Security”) without any action required by or on behalf of the Holder thereof. The Company shall at least 15 days but not more than 30 days
before the Resale Restriction Termination Date, deliver a notice of Automatic Exchange (the “Automatic Exchange Notice”) to each Holder and to the Trustee, which Automatic Exchange Notice shall identify the Securities subject to the
Automatic Exchange and shall state: (1) the date of the Automatic Exchange; (2) the CUSIP number of the Restricted Global Security being exchanged; and (3) the CUSIP number of the Unrestricted Global Security for which such Restricted
Global Security is being exchanged. 
 At the Company’s request, upon reasonable prior notice, the Trustee shall deliver,
in the Company’s name and at its expense, the Automatic Exchange Notice to each Holder; provided, however, that the form and content of such Automatic Exchange Notice shall be prepared by the Company. In connection with an Automatic
Exchange pursuant to this Section 2.18, the Trustee shall be entitled to receive from the Company, and rely conclusively upon, an Officers’ Certificate and an Opinion of Counsel to the Company, each in form and in
substance reasonably satisfactory to the Trustee, to the effect that such Automatic Exchange complies with the Securities Act. Upon an Automatic Exchange pursuant to this Section 2.18 and in accordance with Depositary
procedures, the Registrar shall reflect on its books and records the date of such Automatic Exchange and a decrease and increase, respectively, in the principal amount of the applicable Restricted Global Security(ies) and the Unrestricted Global
Security(ies), respectively, equal to the principal amount of beneficial interests transferred pursuant to such Automatic Exchange. If an Unrestricted Global Security is not then outstanding at the time of an Automatic Exchange, then the Company
shall execute, and upon receipt of a Company Order, the Trustee shall authenticate and deliver, an Unrestricted Global Security to the Depositary. Following any Automatic Exchange, each resulting Restricted Global Security whose principal amount is
reduced to zero shall be cancelled. 

  
 -31-










	2.19	RANKING. 


The indebtedness of the Company arising under or in connection with this Indenture and every outstanding Security issued under this
Indenture from time to time constitutes and will constitute a senior obligation of the Company, ranking equally with other existing and future senior indebtedness of the Company and ranking senior to any existing or future subordinated indebtedness
of the Company. 
  

	2.20	POST-EXCHANGE NOTES. 

 Upon receipt by the Trustee of an Officers’ Certificate stating that an Exchange Offer Registration Statement has become effective under the Securities Act and that a specified principal amount of
Pre-Exchange Securities have been duly tendered for exchange pursuant to such Exchange Offer, and containing any other information as the Trustee may reasonably request, the Trustee shall, upon receipt of certificates for, or book-entry transfer of,
such Pre-Exchange Securities, promptly cancel such Pre-Exchange Securities and authenticate and deliver such specified principal amount of Securities in the form of Post-Exchange Securities to or upon a Company Order. As a condition precedent to the
Trustee’s obligations under this Section 2.20, the Company shall deliver to the Trustee an executed Global Security or Global Securities representing the Post-Exchange Securities to be issued and any Opinion of Counsel
reasonably requested by the Trustee. 
 III. REDEMPTION AND REPURCHASE 

 

	3.01	RIGHT OF REDEMPTION AND REPURCHASE. 


(A) A redemption or repurchase of the Securities by the Company, as permitted by any provision of this Indenture, shall be made:

 (i) with respect to a repurchase at the Company’s option, in accordance with
Section 3.01(D), Section 3.01(E) or Section 3.01(F) (a “Redemption”); or 

(ii) with respect to any repurchase in accordance with Section 3.08 (a “Repurchase Upon Fundamental
Change”); or 
 (iii) with respect to any repurchase in accordance with Section 3.09 (a
“Repurchase Upon Asset Sale”), 
 in each case in accordance with the applicable provisions of this
Article III. 
 (B) The Company will comply with all federal and state securities laws, and the applicable
laws of any foreign jurisdiction, in connection with any offer to sell or solicitations of offers to buy Securities pursuant to this Article III and if such securities laws conflict with the provisions of this Article III,
the securities law provisions shall apply. 
 (C) The Company shall not have the right to redeem any Securities except pursuant
to Section 3.01(D), Section 3.01(E) or Section 3.01(F). 
 (D) At any time prior to
May 9, 2015, the Company may, at its option redeem all or a part of the Securities, upon not less than 30 and not more than 60 days’ prior notice mailed by first-class mail to the registered address of each Holder of Notes, at a redemption
price equal to 100% of the outstanding aggregate principal amount at maturity of the Securities redeemed plus the Applicable Premium as of the date of redemption (the “Redemption Date”), and accrued and unpaid interest to the
Redemption Date. 

  
 -32-









 (E) At any time prior to May 9, 2015, the Company may, at its option, redeem up to 35%
of the aggregate principal amount of Securities issued by it at a redemption price equal to the Equity Offering Redemption Price of such Securities, plus accrued and unpaid interest on such Securities to the applicable Redemption Date, with the net
cash proceeds of one or more Equity Offerings; provided that at least 65% of the sum of the aggregate principal amount of the Securities originally issued under this Indenture remains outstanding immediately after the occurrence of each such
redemption; provided further that each such redemption occurs within 90 days of the date of closing of each such Equity Offering. Notice of any redemption upon any Equity Offering may be given not less than 30 and not more than 60 days prior
to the redemption thereof, and any such redemption or notice may, at the Company’s discretion, be subject to one or more conditions precedent, including, but not limited to, completion of the related Equity Offering. 

(F) Except pursuant to clause (D) or (E) of this Section 3.01, the Securities will not be redeemable at the
Issuer’s option prior to May 9, 2015. 
 (G) On and after May 9, 2015, the Company may, at its option, redeem
Securities, in whole or in part, upon not less than 30 nor more than 60 days’ prior notice by first-class mail, postage prepaid, with a copy to the Trustee, to each Holder of Securities at the address of such Holder appearing in the security
register, at the redemption prices (expressed as percentages of the outstanding aggregate principal amount at maturity of the Securities to be redeemed) set forth below, plus accrued and unpaid interest thereon to the applicable Redemption Date,
subject to the right of Holders of record on the relevant Record Date to receive interest due on the relevant Interest Payment Date, if redeemed during the twelve-month period beginning on May 9 of each of the years indicated below: 

 

					
	 Year

	 2015
	  	 	106.000	% 
	 2016
	  	 	103.000	% 
	 2017 and thereafter
	  	 	100.000	% 

 (H) Notwithstanding anything herein to the contrary, (i) in no event shall any Redemption Date be a
Legal Holiday; and (ii) the redemption prices set forth in this Section 3.01, plus accrued interest up to but excluding the Redemption Date shall be owing to the Holder upon surrender of such Security. 

(I) Securities in denominations larger than $2,000 principal amount may be redeemed in part but only in integral multiples of $1,000
principal amount. 

  
 -33-










	3.02	NOTICES TO TRUSTEE. 

 If the Company elects to redeem Securities pursuant to Sections 3.01(D), (E) or (F), it shall notify the Trustee of the Redemption Date, the
applicable provision of this Indenture pursuant to which the Redemption is to be made and the aggregate principal amount of Securities to be redeemed and the applicable redemption price, which notice shall be provided to the Trustee by the Company
at least 15 days prior to the delivery, in accordance with Section 3.04, of the notice of Redemption (unless a shorter notice period shall be satisfactory to the Trustee). 

 

	3.03	SELECTION OF SECURITIES TO BE REDEEMED. 


If the Company has elected to redeem less than all the Securities pursuant to Sections 3.01(D),
(E) or (F), the Trustee shall, within five Business Days after receiving the notice specified in Section 3.02, select the Securities to be redeemed by lot, on a pro rata basis or in accordance with
any other method the Trustee considers fair and appropriate or is required by the Depositary for the Securities. The Trustee shall make such selection from Securities then outstanding and not already to be redeemed by virtue of having been
previously called for Redemption. Securities and portions of them the Trustee selects for Redemption shall be in a minimum amount of $2,000 or integral multiples of $1,000 in excess thereof; provided that the principal amount of any remaining
Security is at least $2,000. The Trustee shall promptly notify the Company in writing of the Securities selected for Redemption and the principal amount thereof to be redeemed. 

The Registrar need not register the transfer of or exchange any Securities that have been selected for Redemption, except the unredeemed
portion of the Securities being redeemed in part. 
  

	3.04	NOTICE OF REDEMPTION. 

 At least 30 days but not more than 60 days before a Redemption Date, the Company shall mail, or cause to be mailed, by first-class mail a notice of Redemption to each Holder whose Securities are
to be redeemed, at the address of such Holder appearing in the security register. 
 The notice shall identify the Securities
and the aggregate principal amount thereof to be redeemed pursuant to the Redemption and shall state: 
 (i) the Redemption
Date; 
 (ii) the applicable redemption price plus accrued and unpaid interest, if any, to, but excluding, the Redemption Date;

 (iii) the name and address of the Paying Agent; 
 (iv) the Section of the Indenture pursuant to which the Securities are to be redeemed; 
 (v) that the Accreted Value of the Securities or portions of them called for redemption shall cease to increase on and after the Redemption Date; 

(vi) that Securities called for Redemption must be surrendered to the Paying Agent to collect the redemption price plus accrued and
unpaid interest, if any, payable as herein provided upon Redemption; 

  
 -34-









 (vii) that, unless there shall be a Default in the payment of the Redemption price or
accrued and unpaid interest, if any, payable as herein provided upon Redemption, interest on Securities called for Redemption ceases to accrue on and after the applicable Redemption Date and all rights of the Holders with respect to such Securities
shall terminate on and after such Redemption Date, other than the right to receive, upon surrender of such Securities and in accordance with this Indenture, the amounts due hereunder on such Securities upon Redemption (and the rights of the
Holder(s) of record of such Securities to receive, on the applicable interest payment date, accrued and unpaid interest on such Securities in accordance herewith in the event such Redemption Date is after a record date for the payment of an
installment of interest and on or before the related interest payment date); 
 (viii) the CUSIP number or numbers, as the case
may be, of the Securities; and 
 (ix) in the case of a redemption of Notes pursuant to
Section 3.01(E), whether the redemption is subject to any conditions precedent (it being understood that only redemptions under Section 3.01(F) may be subject to any conditions
precedent), and if so, that in the event that any or all conditions are not satisfied by the redemption date, the Company will have the discretion to delay the redemption date until such time as any or all the conditions are satisfied, so long as
the redemption occurs within 60 days of such notice, or to rescind the notice and cancel the redemption. 
 At the
Company’s request, upon 45 days written notice prior to the Redemption Date (or such shorter period that is acceptable to the Trustee), the Trustee shall mail the notice of Redemption in the Company’s name and at the Company’s
expense; provided, however, that the form and content of such notice shall be prepared by the Company. 
  

	3.05	EFFECT OF NOTICE OF REDEMPTION. 


Once notice of Redemption is mailed, subject to clause (viii) of Section 3.04, Securities called for
Redemption become due and payable on the Redemption Date at the consideration set forth herein, and, on and after such Redemption Date (unless there shall be a Default in the payment of such consideration), except as otherwise provided herein, such
Securities shall cease to bear interest, and all rights of the Holders with respect to such Securities shall terminate, other than the right to receive such consideration upon surrender of such Securities to the Paying Agent (except that, if the
Redemption Date is after a record date for the payment of an installment of interest and on or before the related interest payment date, then accrued and unpaid interest on such Securities to, but excluding, such interest payment date will be paid,
on such interest payment date, to the Holder(s) of record of such Securities at the close of business on such record date without any requirement to surrender such Securities to the Paying Agent). 

If any Security shall not be fully and duly paid in accordance herewith upon Redemption, the Accreted Value of, and accrued and unpaid
interest on, such Security shall, until paid, bear interest at the rate borne by such Security on the principal amount of such Security. 
 Notwithstanding anything herein to the contrary, there shall be no purchase of any Securities pursuant to a Redemption if the principal amount of the Securities has been accelerated pursuant to

 If such Securities are held in book-entry form through the Depositary, the Purchase Notice shall comply with applicable procedures of the Depositary. 

Notwithstanding anything herein to the contrary, any Holder that has delivered the Purchase Notice contemplated by this
Section 3.08(A) to the Company (if it is acting as its own Paying Agent) or to a Paying Agent designated by the Company for such purpose in the Fundamental Change Notice shall have the right to withdraw such Purchase
Notice by delivery, at any time prior to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date, of a written notice of withdrawal to the Company (if acting as its own Paying Agent) or the Paying
Agent, which notice shall contain the information specified in Section 3.08(B)(xi). 

The Paying Agent shall promptly notify the Company of the receipt by it of any Purchase Notice or written notice of withdrawal thereof.

 (B) No later than 15 Business Days after the occurrence of a Fundamental Change, the Company shall mail, or cause to be
mailed, to all Holders of record of the Securities at their addresses shown in the register of the Registrar, and to beneficial owners as required by applicable law, a notice (the “Fundamental Change Notice”) of the occurrence of
such Fundamental Change and the Fundamental Change Repurchase Right arising as a result thereof. The Company shall deliver a copy of the Fundamental Change Notice to the Trustee and issue a press release through a national newswire. For the

Change; 
 (iii) the Fundamental Change Repurchase Date;

clause (viii) above; provided, however, that if such Fundamental Change Repurchase Date is after a record date for the payment of an installment of interest and on or before the related interest payment date, then the accrued
and unpaid interest, if any, on such Security to, but excluding, such interest payment date will be paid on such interest payment date to the Holder of record of such Security at the close of business on such record date (without any surrender of
such Securities by such Holder), and the Holder surrendering such Security for repurchase will not be entitled to any such accrued and unpaid interest unless such Holder was also the Holder of record of such Security at the close of business on such
record date; 
 (xii) that, except as otherwise provided herein, on and after such Fundamental Change Repurchase Date (unless
there shall be a Default in the payment of the consideration payable as herein provided upon Repurchase Upon Fundamental Change), interest on Securities subject to Repurchase Upon Fundamental Change will cease to accrue, and all rights of the
Holders with respect to such Securities shall terminate, other than the right to receive, in accordance herewith, the consideration payable as herein provided upon Repurchase Upon Fundamental Change;

 -38-









 
Securities of such Holder to be so withdrawn, which amount must be in a minimum amount of $2,000 or an integral multiple of $1,000 in excess thereof and (V) the principal amount, if any, of
the Securities of such Holder that remain subject to the Purchase Notice delivered by such Holder in accordance with this Section 3.08, which amount must be in a minimum amount of $2,000 or an integral multiple of $1,000 in excess
thereof; 
 (xiv) the CUSIP number or numbers, as the case may be, of the Securities; and

Repurchase Right is conditional on the consummation of that Fundamental Change. 
 At the Company’s request, upon
reasonable prior notice, the Trustee shall mail such Fundamental Change Notice in the Company’s name and at the Company’s expense; provided, however, that the form and content of such Fundamental Change Notice shall be prepared by
the Company. 
 No failure of the Company to give a Fundamental Change Notice shall limit any Holder’s right to exercise a
Fundamental Change Repurchase Right. 
 (C) Subject to the provisions of this Section 3.08, the
Company shall pay, or cause to be paid, the Fundamental Change Repurchase Price, plus accrued and unpaid interest, if any, to, but excluding, the Fundamental Change Repurchase Date, with respect to each Security as to which the Fundamental Change
Repurchase Right shall have been exercised to the Holder thereof as promptly as practicable, but in no event later than the later of the Fundamental Change Repurchase Date and the time such Security (together with all necessary endorsements) is
surrendered or transferred, by book-entry, to the Paying Agent; provided, however, that if such Fundamental Change Repurchase Date is after a record date for the payment of an installment of interest and on or before the related interest
payment date, then the accrued and unpaid interest, if any, on such Security to, but excluding, such interest payment date will be paid on such interest payment date to the Holder of record of such Security at the close of business on such record
date, and the Holder surrendering such Security for repurchase will not be entitled to any such accrued and unpaid interest unless such Holder was also the Holder of record of such Security at the close of business on such record date.

Paying Agent shall return to the Company, as soon as practicable, any excess money not required for that purpose. 
 (E) Once
the Fundamental Change Notice and the Purchase Notice have been duly given in accordance with this Section 3.08 (and subject to Section 3.08(b)), the Securities to be repurchased pursuant to a Repurchase Upon
Fundamental Change shall, on the Fundamental Change Repurchase Date, become due and payable in accordance herewith, and, on and after such date (unless there shall be a Default in the payment of the consideration payable as herein


  
 -39-









 
provided upon Repurchase Upon Fundamental Change), except as otherwise herein provided, such Securities shall cease to bear interest, and all rights of the Holders with respect to such Securities
shall terminate, other than the right to receive, in accordance herewith, such consideration. 
 (F) If any Security shall not
be paid upon surrender thereof for Repurchase Upon Fundamental Change, the Accreted Value of, and accrued and unpaid interest on, such Security shall, until paid, bear interest, payable in cash, at the rate borne by such Security on the principal
amount of such Security. 
 (G) Any Security which is to be submitted for Repurchase Upon Fundamental Change only in part shall
be delivered pursuant to this Section 3.08 (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the
Holder thereof or its attorney duly authorized in writing), and the Company shall execute, and the Trustee, upon receipt of a Company Order, shall authenticate and make available for delivery to the Holder of such Security without service charge, a
new Security or Securities, of any authorized denomination as requested by such Holder, of the same tenor and in aggregate principal amount equal to the portion of such Security not duly submitted for Repurchase Upon Fundamental Change. 

(H) Notwithstanding anything herein to the contrary, there shall be no purchase of any Securities pursuant to this
Section 3.08 if the principal amount of the Securities has been accelerated pursuant to Section 6.02 and such acceleration shall not have been rescinded on or before the applicable Fundamental
Change Repurchase Date. The Paying Agent will promptly return to the respective Holders thereof any Securities tendered to it for Repurchase Upon Fundamental Change during the continuance of such an acceleration. 

(I) Notwithstanding anything herein to the contrary, if the option granted to Holders to require the repurchase of the Securities upon
the occurrence of a Fundamental Change is determined to constitute a tender offer, the Company shall comply with all applicable tender offer rules under the Exchange Act, including Rule 13e-4 and Regulation 14E thereunder, and with all
other applicable laws, and will file a Schedule TO or any other schedules required under the Exchange Act or any other applicable laws.

direct or indirect “beneficial owner,” as defined in Rule 13d-3 under the Exchange Act, of the Common Stock of the Company representing more than 50% of the voting power of the Common Stock of the Company; 

  
 -40-









 (ii) the consummation of (A) any recapitalization, reclassification or change, in each
case, of the Common Stock (other than changes resulting from a stock split, subdivision, or combination) as a result of which the Common Stock would be converted into, or exchanged for, stock, other securities, other property or assets or
(B) any share exchange, consolidation or merger of the Company pursuant to which the Common Stock will be converted into cash, securities or other property or (C) any sale, lease or other transfer in one transaction or a series of
transactions of all or substantially all of the consolidated assets of the Company and its Subsidiaries, taken as a whole, to any Person other than one or more of the Company’s Restricted Subsidiaries; provided, however, that a
transaction described in clause (B) in which the holders of all classes of the Common Stock of the Company immediately prior to such transaction own, directly or indirectly, more than 50% of the voting power of the continuing or surviving
corporation or transferee or the parent thereof immediately after such transaction in substantially the same proportions as such ownership immediately prior to such transaction shall not be a Fundamental Change pursuant to this clause (ii);

 (iii) the stockholders of the Company approve any plan or proposal for the liquidation or dissolution of the Company;

 (iv) the Common Stock (or other common stock underlying the Notes) ceases to be listed or quoted on any of The New York Stock
Exchange, The NASDAQ Global Select Market, The NASDAQ Global Market or The NASDAQ Capital Market (or any of their respective successors); provided, however, that a transaction or transactions described in clause (ii) above shall
not constitute a Fundamental Change, if at least 90% of the consideration received or to be received by the common stockholders of the Company, excluding cash payments for fractional shares and cash payments made in respect of dissenters’
appraisal rights, in connection with such transaction or transactions consists of shares of Publicly Traded Securities, and as a result of such transaction or transactions the Notes become convertible into such Publicly Traded Securities, excluding
cash payments for fractional shares and cash payments made in respect of dissenters’ appraisal rights (subject to the provisions of this Section 3.08); or 
 (v) a Krystexxa Sale. 
 Notwithstanding anything to the contrary in this
Section 3.08, no Holder shall have a Fundamental Change Repurchase Right as a result of any Restricted Merger or Sale Transaction that is also a Fundamental Change if all requirements of Section 5.01(A) through (C) have been
satisfied in respect of such Restricted Merger or Sale Transaction.

co-Registrar) where Securities may be surrendered for registration of transfer or exchange or payment. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any
time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations and surrenders may be made at the Corporate Trust Office of the Trustee. 

The Company may also from time to time designate one or more other offices or agencies where the Securities may be presented or
surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or
agency for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. 

The Company hereby designates the Corporate Trust Office of the Trustee as an agency of the Company in accordance with
Section 2.03.

	4.03	REPORTS. 


(A) At any time any Securities bear the Private Placement Legend and when the Company is not subject to Sections 13 or 15(d) of
the Exchange Act, the Company shall promptly provide to the Trustee and shall, upon request, provide to any Holder, beneficial owner or prospective purchaser of Securities, the information required to be delivered pursuant to
Rule 144A(d)(4) under the Securities Act to facilitate the resale of such Securities pursuant to Rule 144A. The Company shall take such further action as any Holder or beneficial holder of such Securities may reasonably request to the
extent required from time to time to enable such Holder or beneficial holder to sell its Securities in accordance with Rule 144A, as such rule may be amended from time to time. 

(B) The Company shall file with the Trustee within 15 days after the same are required to be filed with the SEC, copies of any documents
or reports that the Company is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act (giving effect to any grace period provided by Rule 12b-25 under the Exchange Act). Any such document or report that
the Company files with the SEC via the Commission’s EDGAR or IDEA system shall be deemed to be filed with the Trustee for purposes of this Section 4.03(B) at the time such documents are filed via the EDGAR or IDEA system. Delivery
of the reports and documents described in this Section 4.03(B) above to the Trustee is for informational purposes only, and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein
or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to conclusively rely on an Officers’ Certificate). 

(C) If this Indenture is qualified under the TIA, the Company shall furnish to the Trustee and the Collateral Agent on a semi-annual
basis, an Officer’s Certificate stating that (if applicable) all dispositions of Collateral made during the preceding six-month period were made in the ordinary course of business. 

 

	4.04	COMPLIANCE CERTIFICATE. 

 The Company shall deliver to the Trustee, within 90 calendar days after the end of each fiscal year of the Company or, if earlier, by the date the Company is, or would be, required to file with the SEC

Default or Event of Default by the Company in performing any of its obligations under this Indenture or the Securities. If such signatories do know of any such Default or Event of Default on such date, then such Officers’ Certificate shall
describe the Default or Event of Default and its status. 
  

	4.05	STAY, EXTENSION AND USURY LAWS. 


Each of the Company and the Guarantors covenants (to the extent that it may lawfully do so) that it will 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 wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and each of
the Company and the Guarantors (in each case, to the extent that it may lawfully do so) hereby expressly waives all benefit 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 Trustee, but will suffer and permit the execution of every such power as though no such law has been enacted.

	4.06	CORPORATE EXISTENCE. 

 Subject to Article V, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence and the corporate existence of each of
its Significant Subsidiaries, in accordance with the respective organizational documents of the Company and of each of its Significant Subsidiaries, and the rights (charter and statutory), licenses and franchises of the Company and its Significant
Subsidiaries; provided, however, that the Company shall not be required to preserve any such right, license or franchise, or the corporate existence of any of its Subsidiaries, if in the good faith judgment of the Company (i) such
preservation or existence is not material to the conduct of business of the Company and (ii) the loss of such right, license or franchise or the dissolution of such Subsidiary does not have a material adverse impact on the ability of Holders to
be repaid. 
  

	4.07	NOTICE OF DEFAULT. 

 Upon becoming aware of any Default or Event of Default, the Company shall give written notice of such Default or Event of Default within 15 days thereof, and any remedial action proposed to be taken,
to the Trustee unless such Default or Event of Default has been cured within the 15-day period. 
  

	4.08	PAYMENT OF TAXES. 

 The Company shall pay or discharge or cause to be paid or discharged, before the same shall become delinquent, all material taxes, assessments and governmental charges (including, without limitation,
withholding taxes and any penalties, interest and additions to taxes) levied or imposed upon the Company or any of its Restricted Subsidiaries or the properties of the Company or any of its Restricted Subsidiaries; provided, however, that the
Company shall not be required, pursuant to this Section 4.08, to pay or discharge or cause to be paid or discharged any such tax, assessment or charge whose amount, applicability or validity is, or will be, contested in
good faith by appropriate proceedings properly instituted and diligently conducted and for which adequate reserves, to the extent required under GAAP, have been taken. 
  


	4.09	MAINTENANCE OF PROPERTIES AND INSURANCE. 


(A) The Company shall, and shall cause each of its Restricted Subsidiaries to, maintain its properties in good working order and condition
in all material respects (subject to ordinary wear and tear) and make all necessary repairs, renewals, replacements, additions, betterments and improvements thereto and actively conduct and carry on its business; provided, however, that
nothing in this Section 4.09 shall prevent the Company or any of its Restricted Subsidiaries from discontinuing the operation and maintenance of any of its properties if such discontinuance is, in the good faith judgment of
the Company, desirable in the conduct of the business of Company and its Subsidiaries, taken as a whole. 
 (B) The Company
shall maintain insurance (including, without limitation, appropriate self-insurance) against loss or damage of the kinds that, in the good faith judgment of the Company, are adequate and appropriate for the conduct of the business of the Company and
its Restricted Subsidiaries in a prudent manner, with reputable insurers or with the government of the United States or an agency or instrumentality thereof, in such amounts, with such deductibles, and by such methods, as shall be prudent, in the
good faith judgment of the 

  
 -48-









 
Company, in each case unless the failure to maintain such insurance would not, in the good faith judgment of the Company, have a material adverse effect on the financial condition or results of
operations of the Company and its Subsidiaries, taken as a whole. Each such policy of insurance shall (i) name Collateral Agent, on behalf of the Secured Parties, as an additional insured thereunder as its interests may appear, (ii) in the
case of each casualty insurance policy, contain a loss payable clause or endorsement, satisfactory in form to the Collateral Agent, that names Collateral Agent, on behalf of the Secured Parties, as the loss payee thereunder and provide for at least
thirty days’ prior written notice to Collateral Agent of any modification or cancellation of such policy.

within 90 days after such exchange, sale or receipt of such cash capital contribution; 
 (iii) the acquisition of any
Indebtedness of the Company or the Guarantors that is either (i) senior unsecured Indebtedness or Indebtedness secured by a Lien on the Collateral that is junior to the Lien securing the Obligations or (ii) subordinate or junior in right
of payment to the Securities or a Subsidiary Guarantee (in each case, a “Subordinated Obligation”), either (1) solely in exchange for shares of Qualified Capital Stock of the Company; or (2) through the application of net

after such sale or receipt of such cash capital contribution; 
 (iv) an Investment either (1) solely in exchange for

	4.12	LIMITATIONS ON TRANSACTIONS WITH AFFILIATES. 


(A) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, enter into or permit to exist

 (i) Affiliate Transactions permitted by Section 4.12(B); and


  
 -50-









 (ii) Affiliate Transactions on terms that are no less favorable than those that might
reasonably have been obtained in a comparable transaction at such time on an arm’s-length basis from a Person that is not an Affiliate of the Company or such Restricted Subsidiary. 

With respect to Affiliate Transactions (other than those described in Section 4.12(B)) completed in any fiscal
quarter of the Company, the Company shall deliver an Officers’ Certificate to the Trustee within 10 Business Days of the end of such fiscal quarter certifying that such transactions are in compliance with
Section 4.12(A)(ii) (it being understood that such officer may rely on a third-party expert in arriving at any such determination). All Affiliate Transactions (and each series of related Affiliate Transactions which
are similar or part of a common plan) involving aggregate payments or other property with a Fair Market Value in excess of $500,000 shall be approved by a majority of the members of the Board of Directors (including a majority of the disinterested
members thereof), such approval to be evidenced by a Board Resolution stating that such Board of Directors has determined that such transaction complies with the foregoing provisions. If the Company or any Restricted Subsidiary of the Company enters
into an Affiliate Transaction (or a series of related Affiliate Transactions related to a common plan) that involves an aggregate Fair Market Value of more than $5,000,000, then the Company shall, prior to the consummation thereof, obtain a

(iv) Restricted Payments permitted by this Indenture and Permitted Investments of the type described in the definition thereof;

 (v) any merger or other transaction with an Affiliate solely for the purpose of reincorporating the Company in another

guarantee, acquire, become liable, contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness, including Acquired Indebtedness (other than Permitted Indebtedness). 

(B) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, incur any Indebtedness which
by its terms (or by the terms of any agreement governing such Indebtedness) is subordinated in right of payment to any other Indebtedness of the Company or such Restricted Subsidiary, unless such Indebtedness is also by its terms (or by the terms of
any agreement governing such Indebtedness) made expressly subordinate to the Obligations of the Company or such Restricted Subsidiary under (i) in the case of the Company, the Securities and this Indenture or (ii) in the case of such
Restricted Subsidiary, its Subsidiary Guarantee and this Indenture, in each case, to the same extent and in the same manner as such Indebtedness is subordinated to other Indebtedness of the Company or such Restricted Subsidiary. Unless otherwise
expressly set forth in this Indenture, no Indebtedness will be deemed to be subordinated in right of payment to any other Indebtedness of the Company or any Restricted Subsidiary solely by virtue of such Indebtedness being unsecured, having a junior
lien on any collateral (whether by intercreditor agreement, operation of law, or otherwise), lacking a security interest in any assets that secure other Indebtedness, or lacking one or more guarantees granted to other Indebtedness. 

(C) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, issue any Disqualified
Capital Stock. 
  

	4.14	LIMITATION ON DIVIDEND AND OTHER PAYMENT RESTRICTIONS
AFFECTING RESTRICTED SUBSIDIARIES.

 (2) this Indenture, the Notes, the Subsidiary Guarantees and the Collateral Documents;

 (3) customary non-assignment provisions of any contract governing a leasehold interest of or any lease of any Restricted
Subsidiary of the Company; 
 (4) any instrument governing Acquired Indebtedness, which encumbrance or restriction is not
applicable to any Person, or the properties or assets of any Person, other than the Person or the properties or assets of the Person so acquired; 
 (5) agreements existing on the Issue Date to the extent and in the manner such agreements are in effect on the Issue Date; 
 (6) restrictions on the transfer of assets subject to any Lien permitted under this Indenture; 
 (7) restrictions imposed by any agreement to sell assets or Capital Stock permitted under this Indenture to any Person pending the closing of such sale;

similar entity or the equity interests therein); 
 (9) restrictions in other Indebtedness incurred in compliance with
Section 4.13 (including Permitted Indebtedness), provided that (i) such restrictions, taken as a whole, are, in the good faith judgment of the Board of Directors, no more materially restrictive with respect to such
encumbrances and restrictions than those customary in comparable financings and (ii) the Company determines that any such encumbrance or restriction will not materially affect the Company’s ability to make principal, premium, if any, or
interest, if any, on payments on the Securities or any Guarantor’s ability to honor its Subsidiary Guarantee in respect thereof; or 
 (10) an agreement governing Indebtedness incurred to Refinance the Indebtedness issued, assumed or incurred pursuant to an agreement referred to in clause (2), (4), (5) or (6) above, provided
that the provisions relating to such encumbrance or restriction contained in any such Indebtedness are no less favorable to the Company in any material respect, as determined by the Board of Directors, than the provisions relating to such
encumbrance or restriction contained in agreements referred to in such clause (2), (4), (5) or (6). 
  

	4.15	LIMITATION ON ASSET SALES. 


(A) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, consummate an Asset Sale
unless: 
 (i) the Company or such Restricted Subsidiary, as the case may be, receives consideration at the time of such Asset
Sale equal to or greater than the Fair Market Value of the assets sold or otherwise disposed of pursuant to such Asset Sale; 

  
 -53-









 (ii) at least 75% of the consideration received by the Company or such Restricted
Subsidiary, as the case may be, from such Asset Sale is in the form of cash, Cash Equivalents or Designated Non-Cash Consideration and is received at the time of such Asset Sale; provided, however, that the following shall be deemed to be
cash for purposes of this Section 4.15(A)(ii): (a) the amount of any liabilities (as shown on the most recent applicable balance sheet) of the Company or such Restricted Subsidiary (other than liabilities that are by
their terms subordinated to the Securities) that are assumed by the transferee of the assets sold or otherwise disposed of pursuant to such Asset Sale and (b) the Fair Market Value of any securities or other assets received by the Company or
such Restricted Subsidiary in exchange for such assets, which securities or assets are converted into cash or Cash Equivalents within 180 days after such Asset Sale; and 
 (iii) the Company applies, or causes such Restricted Subsidiary to apply, the Net Cash Proceeds relating to such Asset Sale or any Net Loss Proceeds from an Event of Loss, as applicable, within
180 days of receipt thereof, either: 
 (a) to make an investment in property, plant, equipment or other
tangible or intangible non-current assets (including any intellectual property or other rights to manufacture and sell pharmaceuticals) that replace the properties and assets that were the subject of such Asset Sale or Event of Loss, as applicable,
or that will be used or useful in a Permitted Business (including, without limitation, expenditures for maintenance, repair or improvement of existing properties and assets and research and development costs and expenses), or to make a capital
expenditure, or to acquire all of the Capital Stock of a Person engaged in a Permitted Business; provided that to the extent the subject of the Asset Sale or Event of Loss constituted Collateral, the acquired properties and assets shall be
pledged as additional Collateral in accordance with and pursuant to the Collateral Documents; 
 (b) to repay or
repurchase Indebtedness secured by the property or assets that were the subject of the Asset Sale or Event of Loss, as applicable, but only to the extent that Indebtedness requires such a repayment or repurchase; 

(c) solely with respect to any Asset Sale, to make an offer to repurchase, or to repurchase, Securities pursuant to a
Repurchase Upon Asset Sale in accordance with Section 3.09; 
 (d) solely with respect
to any Asset Sale, for any other purpose; provided, however, that the aggregate maximum amount pursuant to which the Company may apply pursuant to this Section 4.15(A)(iii)(d) with respect to all Asset
Sales occurring on or after the Issue Date shall not exceed $1,000,000; and 
 (e) any combination of the
foregoing. 
 For the avoidance of doubt, if the Company shall, in compliance with Section 4.15(A),
make an offer to repurchase, with a specified amount of Net Cash Proceeds, Securities pursuant to a Repurchase Upon Asset Sale in accordance with Section 3.09 and if the aggregate Asset Sale Repurchase Price in respect of
all Securities tendered for repurchase pursuant to such Repurchase Upon Asset Sale is less than such specified amount of Net Cash Proceeds, then the excess of such specified amount of Net Cash Proceeds over such aggregate Asset Sale Repurchase Price
shall be deemed to have been properly applied by the Company pursuant to Section 4.15(A)(iii). 

  
 -54-









 If, on the date that is 181 days after the receipt of Net Cash Proceeds in connection
with an Asset Sale or Net Loss Proceeds in connection with an Event of Loss, as applicable, not all of such Net Cash Proceeds or Net Loss Proceeds, as applicable, were applied pursuant to Section 4.15(A)(iii), then such
date shall be deemed to be the date that the Company is required, pursuant to Section 4.15(A)(iii), to make an offer to repurchase Securities; and the amount (the “Required Offer Amount”) that the Company is required to
offer to repurchase Securities pursuant to Section 3.09 shall be the amount of all Net Cash Proceeds and Net Loss Proceeds, as applicable, in respect of all Asset Sales and Events of Loss occurring before such date, that
were not theretofore applied pursuant to Section 4.15(A)(iii). 
 For the avoidance of
doubt, the Company may not apply the Net Cash Proceeds of any Krystexxa Sale for any purpose described in Section 4.15(A)(iii). 
  

	4.16	LIMITATION ON LIENS. 

 The Company will not, and will not cause or permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume or permit any Liens (other than Permitted Liens) of any kind to

priorities of the Liens securing the Securities and Obligations in respect thereof, on the one hand, and the junior and subordinated Liens securing Existing Notes or any Exchange Indebtedness or Refinancing Indebtedness in respect thereof, on the

except in the case of a sale of all of the Company’s assets that meets the requirements of Section 5.01 hereof. 

VI. DEFAULTS AND REMEDIES

of this Indenture or the Collateral Documents or (ii) as a result of the release of a Guarantor or the sale or other disposition of the applicable Collateral in a transaction permitted hereunder or under the Collateral Documents); 

  
 -58-









 (viii) except as permitted by this Indenture, any Subsidiary Guarantee of a Significant
Subsidiary shall be held in any final, non-appealable judicial proceeding to be unenforceable or invalid or shall cease for any reason to be in full force and effect or any Guarantor that is a Significant Subsidiary, or any Person acting on behalf
of any Guarantor that is a Significant Subsidiary, shall deny or disaffirm its obligations under its Subsidiary Guarantee; 

(ix) the Company or any of its Significant Subsidiaries or any group of the Company’s Subsidiaries that in the aggregate would
constitute a Significant Subsidiary of the Company, pursuant to, or within the meaning of, any Bankruptcy Law, insolvency law, or other similar law now or hereafter in effect or otherwise, either:

Section 6.01(x), the order or decree remains unstayed and in effect for at least 90 consecutive days. 

  
 -59-









 The term “Bankruptcy Law” means Title 11, U.S. Code or any
similar Federal or State law for the relief of debtors. The term “Custodian” means any receiver, trustee, assignee, liquidator or similar official under any Bankruptcy Law. 

A Default under clause (iv) above is not an Event of Default until (I) the Trustee notifies the Company, or
the Holders of at least 25% in aggregate principal amount of the Securities then outstanding notify the Company and the Trustee, of the Default and (II) the Default is not cured within 60 days after receipt of such notice. Such notice must
specify the Default, demand that it be remedied and state that the notice is a “Notice of Default.” If the Holders of at least 25% in aggregate principal amount of the outstanding Securities request the Trustee to give such notice
on their behalf, the Trustee shall do so. When a Default is cured, it ceases. 
  

	6.02	ACCELERATION. 

 If an Event of Default (excluding an Event of Default specified in Section 6.01(ix) or (x) with respect to the Company (but including an Event of Default specified in
Section 6.01(ix) or (x) solely with respect to a Significant Subsidiary of the Company or any group of the Company’s Subsidiaries that in the aggregate would constitute a Significant Subsidiary of the
Company)) occurs and is continuing, the Trustee by written notice to the Company, or the Holders of at least 25% in aggregate principal amount of the Securities then outstanding by written notice to the Company and the Trustee, may declare the
Securities to be immediately due and payable in full. Upon such declaration, the Accreted Value of, and any accrued and unpaid interest on, all Securities shall be due and payable immediately. If an Event of Default specified in
Section 6.01(ix) or (x) with respect to the Company (excluding, for purposes of this sentence, an Event of Default specified in Section 6.01(ix) or (x) solely with respect to a
Significant Subsidiary of the Company or any group of the Company’s Subsidiaries that in the aggregate would constitute a Significant Subsidiary of the Company) occurs, the Accreted Value of, and accrued and unpaid interest on, all the
Securities shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. The Holders of a majority in aggregate principal amount of the Securities then outstanding by
written notice to the Trustee may rescind or annul an acceleration and its consequences if (A) the rescission would not conflict with any order or decree, (B) all existing Events of Default, except the nonpayment of principal or interest
that has become due solely because of the acceleration, have been cured or waived and (C) all amounts due to the Trustee under Section 7.07 have been paid. 

 

	6.03	OTHER REMEDIES. 

 Notwithstanding anything herein to the contrary, if an Event of Default occurs and is continuing, the Trustee may pursue any available remedy by proceeding at law or in equity to collect the payment of
amounts due with respect to the Securities or to enforce the performance of any provision of the Securities or this Indenture and may also direct the Collateral Agent to pursue any available remedy or exercise any rights the Collateral Agent has
pursuant to the Pledge and Security Agreement, other Collateral Documents, or applicable law. 
 The Trustee may maintain a
proceeding even if it does not possess any of the Securities or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the
right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative. 

  
 -60-










	6.04	WAIVER OF PAST DEFAULTS. 


Subject to Sections 6.07 and 11.02, the Holders of a majority in aggregate principal amount of the
Securities then outstanding may, by notice to the Trustee, waive any Default or Event of Default and its consequences, other than (A) a Default or Event of Default in the payment of the Accreted Value of, or premium, if any, or interest on, any
Security, or in the payment of the applicable redemption price, the Fundamental Change Repurchase Price or the Asset Sale Repurchase Price (or accrued and unpaid interest, if any, payable as herein provided, upon Redemption, Repurchase Upon
Fundamental Change or Repurchase Upon Asset Sale) or (B) any Default or Event of Default in respect of any provision of this Indenture or the Securities which, under Section 11.2, cannot be modified or amended without
the consent of the Holder of each outstanding Security affected. When a Default or an Event of Default is waived, it is cured and ceases. If this Indenture is qualified under the TIA, this Section 6.04 shall be in lieu of
TIA § 316(a)(1)(B), and, as permitted by the TIA, TIA § 316(a)(1)(B) is hereby expressly excluded from this Indenture. 
  

	6.05	CONTROL BY MAJORITY. 

 The Holders of a majority in aggregate principal amount of the Securities then outstanding may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or
exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture, is unduly prejudicial to the rights of other Holders or would involve the Trustee in personal liability
unless the Trustee is offered indemnity or security satisfactory to it; provided, that the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction. If this Indenture is qualified under the
TIA, this Section 6.05 shall be in lieu of TIA § 316(a)(1)(A), and, as permitted by the TIA, TIA § 316(a)(1)(A) is hereby expressly excluded from this Indenture. 

 

	6.06	LIMITATION ON SUITS. 

 Except as provided in Section 6.07, a Securityholder may not institute any proceeding under this Indenture, or for the appointment of a receiver or a trustee, or for any other
remedy under this Indenture unless: 
 (i) the Holder gives to the Trustee written notice of a continuing Event of Default;

 (ii) the Holders of at least 25% in aggregate principal amount of the Securities then outstanding make a written request to
the Trustee to pursue the remedy; 
 (iii) such Holder or Holders offer and, if requested, provide to the Trustee indemnity
satisfactory to the Trustee against any loss, liability or expense; 
 (iv) the Trustee does not comply with the request within
60 days after receipt of such notice, request and offer of indemnity; and 
 (v) during such 60 day period, the
Holders of a majority in aggregate principal amount of the Securities then outstanding do not give the Trustee a direction inconsistent with the request. 
 A Securityholder may not use this Indenture to prejudice the rights of another Securityholder or to obtain a preference or priority over another Securityholder. 

  
 -61-










	6.07	RIGHTS OF HOLDERS TO RECEIVE PAYMENT. 


Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of all amounts due with respect to the
Securities, on or after the respective due dates as provided herein, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of the Holder. 

 

	6.08	COLLECTION SUIT BY TRUSTEE. 


If an Event of Default specified in Section 6.01(i) or (ii) occurs and is continuing, the
Trustee may recover judgment in its own name and as trustee of an express trust against the Company for the whole amount due with respect to the Securities, including any unpaid and accrued interest. 

 

	6.09	TRUSTEE MAY FILE PROOFS OF CLAIM. 


The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of
the Trustee, any predecessor Trustee and the Securityholders allowed in any judicial proceedings relative to the Company or its creditors or properties. 
 The Trustee may collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same, and any custodian, receiver, assignee, trustee, liquidator,
sequestrator or similar official in any judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay the
Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents, advisors and counsel, and any other amounts due the Trustee under Section 7.07. 

Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder
any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding; provided,
however, that the Trustee may be a member of a creditor’s or other similar committee. 
  

	6.10	PRIORITIES. 


If the Trustee collects any money pursuant to this Article VI, it shall pay out the money or other property in the
following order: 
  

			
	 First:
	  	to the Trustee for amounts due under Section 7.07 and the Collateral Agent pursuant to the Collateral Documents;
		
	 Second:
	  	to Securityholders for all amounts due and unpaid on the Securities, without preference or priority of any kind, according to the amounts due and payable on the Securities;
and
		
	 Third:
	  	to the Company.

 The Trustee, upon prior written notice to the Company, may fix a record date and payment date for any
payment by it to Securityholders pursuant to this Section 6.10. At least 15 days before each such record date, the Trustee shall mail to each Holder and the Company a written notice that states such record date and
payment date and the amount of such payment. 

  
 -62-










	6.11	UNDERTAKING FOR COSTS. 

 In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the
filing by any party litigant in the suit other than the Trustee of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in the
suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to
Section 6.07 or a suit by Holders of more than 10% in aggregate principal amount of the outstanding Securities. 
 VII. TRUSTEE 
  

	7.01	DUTIES OF TRUSTEE. 

 (A) If an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their
exercise, as a prudent person would exercise or use under the circumstances in the conduct of his or her own affairs.

statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but in the case of any such certificates or opinions which by any
provision hereof are specifically required to be furnished to the Trustee, the Trustee shall examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate
the accuracy of mathematical calculations or other facts stated therein). 
 (C) The Trustee may not be relieved from liability
for its own negligent action, its own negligent failure to act or its own willful misconduct, except that: 
 (i) the Trustee
shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; 

(ii) in no event shall the Trustee be liable for any consequential loss or damage of any kind whatsoever (including but not limited to
lost profits), even if the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action; 
 (iii) the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Sections 6.02

	7.02	RIGHTS OF TRUSTEE. 

 (A) Subject to Section 7.01, the Trustee may conclusively rely on any document believed by it to be genuine and to have been signed or presented by the proper person. The Trustee
need not investigate any fact or matter stated in the document; if, however, the Trustee shall determine to make such further inquiry or investigation, it shall be entitled during normal business hours to examine the relevant books, records and
premises of the Company, personally or by agent or attorney upon reasonable prior notice. 
 (B) Before the Trustee acts or
refrains from acting, it may require an Officers’ Certificate and/or an Opinion of Counsel at the expense of the Company. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on such Officers’
Certificate or Opinion of Counsel. 
 (C) Any request or direction of the Company mentioned herein shall be sufficiently
evidenced by a Company Request or Company Order, and any resolution of the Board of Directors shall be sufficiently evidenced by a Board Resolution.

Article IV (other than Sections 4.04 and 4.07) is for informational purposes only and the Trustee’s receipt of the foregoing shall not constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely on Officers’ Certificates). 

  
 -64-









 (H) The Trustee shall be under no obligation to exercise any of the rights or powers vested
by this Indenture at the request or direction of any of the Holders pursuant to this Indenture unless such Holders shall have offered to the Trustee security or indemnity satisfactory to the Trustee against the costs, expenses and liabilities which
might be incurred by it in compliance with such request or direction. 
 (I) The rights, privileges, protections, immunities and
benefits given to the Trustee, including without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder and under any related document, and each agent, custodian and

setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture, which Officers’ Certificate may be signed by any person authorized to sign an Officers’

otherwise incur any financial liability in the performance of any of its duties hereunder or under any Collateral Document or to take or omit to take any action under this Indenture or under any Collateral Document or take any action at the request
or direction of Holders if it shall have reasonable grounds for believing that repayment of such funds is not assured to it.

ascertaining whether any transfer, exchange, redemption or repurchase complies with the registration provisions of or exemptions from the Securities Act, Exchange Act, applicable state securities laws or other applicable law.

Indenture also shall be afforded to the Collateral Agent, the Warrant Agent and the Trustee in any other capacities under or related to this Indenture acting pursuant to the Collateral Documents. 

 

	7.03	INDIVIDUAL RIGHTS OF TRUSTEE. 


The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company
or any of its Affiliates with the same rights the Trustee would have if it were not Trustee. Any Securities Agent may do the same with like rights. The Trustee, however, must comply with Sections 7.10 and
7.11. 

  
 -65-










	7.04	TRUSTEE’S DISCLAIMER. 

 The Trustee makes no representation as to the validity or adequacy of this Indenture, the Collateral Documents or the Securities; the Trustee shall not be accountable for the Company’s use of the
proceeds from the Securities; and the Trustee shall not be responsible for any statement in the Securities other than its certificate of authentication, or for any calculations required hereunder or for the content of any notices prepared by the
Company. 
  

	7.05	NOTICE OF DEFAULTS. 

 If a Default or Event of Default occurs and is continuing as to which the Trustee has received notice pursuant to the provisions of this Indenture, or as to which a Responsible Officer of the Trustee
shall have actual knowledge, then the Trustee shall mail to each Holder a notice of the Default or Event of Default within 90 days after the Trustee has received notice or has actual knowledge thereof unless such Default or Event of Default has
been cured or waived; provided, however, that, except in the case of a Default or Event of Default in payment of any amounts due with respect to any Security, the Trustee may withhold such notice if, and so long as it in good faith determines
that, withholding such notice is in the interests of Holders. 
  

	7.06	REPORTS BY TRUSTEE TO HOLDERS. 


If this Indenture is qualified by the TIA, within 60 days after each March 15 subsequent thereto, the Trustee shall mail to each
Security holder if required by TIA § 313(a) a brief report dated as of such May 15 that complies with TIA § 313(c). In such event, the Trustee also shall comply with TIA § 313(b). 

A copy of each report at the time of its mailing to Securityholders shall be mailed by first class mail to the Company and filed by the
Trustee with the SEC and each stock exchange, if any, on which the Securities are listed. The Company shall promptly notify the Trustee of the listing or delisting of the Securities on or from any stock exchange. 

 

	7.07	COMPENSATION AND INDEMNITY. 

 The Company shall pay to the Trustee (and any other capacities that it serves in connection herewith, including without limitation, as Collateral Agent and as warrant agent with respect to the Warrants)
from time to time such compensation for its services as shall be agreed upon in writing and for any reasonable extraordinary expenses it incurs. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an
express trust. The Company shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses incurred by it. Such expenses shall include the reasonable compensation and out-of-pocket expenses of the Trustee’s agents, advisors
and counsel. 
 The Company shall indemnify and hold harmless the Trustee and its affiliates, directors, agents, officers and
employees against any and all loss, liability, damage, claim or expense (including the reasonable fees and expenses of counsel and taxes other than those based upon the income of the Trustee) incurred by it in connection with the acceptance or
administration of this trust and the performance of its duties hereunder and any document or transaction entered into in connection herewith or in furtherance thereof or in any other capacity hereunder, including the reasonable costs and expenses of
defending itself against any claim (whether asserted by the Company, any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers and duties hereunder. 

  
 -66-









 The Company need not pay for any settlement made without its consent (such consent not to be
unreasonably withheld). The Trustee shall notify the Company promptly of any claim for which it may seek indemnification; provided that failure to provide any such notice shall not limit the Company’s obligations under this
Section 7.07. The Company need not reimburse any expense or indemnify against any loss or liability incurred by the Trustee through the Trustee’s negligence, bad faith or willful misconduct. 

To secure the Company’s payment obligations in this Section 7.07, the Trustee shall have a lien prior to
the Securities on all money or property held or collected by the Trustee, except that held in trust to pay amounts due on particular Securities. 
 The Company shall pay all amounts owing to the Trustee (including without limitation in its capacity as Collateral Agent and as warrant agent with respect to the Warrants) pursuant to the Collateral
Documents. 
 The obligations of the Company with respect to the Trustee provided for in this
Section 7.07 shall survive any resignation or removal of the Trustee and the termination of this Indenture. 
 When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(ix) or (x) occurs, the expenses and the compensation for
the services are intended to constitute expenses of administration under any Bankruptcy Law. 
  

	7.08	REPLACEMENT OF TRUSTEE. 

 A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee’s acceptance of appointment as provided in this
Section 7.08. 
 The Trustee may resign by so notifying the Company in writing 30 Business Days prior
to such resignation. The Holders of a majority in aggregate principal amount of the Securities then outstanding may remove the Trustee by so notifying the Trustee and the Company in writing and may appoint a successor Trustee with the Company’s
consent. The Company may remove the Trustee if: 
 (i) the Trustee fails to comply with Section 7.10;

 (ii) the Trustee is adjudged a bankrupt or an insolvent; 

(iii) a receiver or other public officer takes charge of the Trustee or its property; or 

(iv) the Trustee becomes incapable of acting. 
 If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint a successor Trustee. 

If a successor Trustee does not take office within 30 days after the retiring Trustee resigns or is removed, the retiring Trustee
(at the Company’s expense), the Company or the Holders of at least 10% in aggregate principal amount of the outstanding Securities may petition any court of competent jurisdiction for the appointment of a successor Trustee. 

If the Trustee fails to comply with Section 7.10, the Company or any Holder may petition any court of competent
jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 

  
 -67-









 A successor Trustee shall deliver a written acceptance of its appointment to the retiring
Trustee and to the Company. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall
mail a notice of its succession to Securityholders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 7.07. 

 

	7.09	SUCCESSOR TRUSTEE BY MERGER, ETC. 


If the Trustee consolidates with, merges or converts into, or transfers or sells all or substantially all of its corporate trust business
to, another corporation, the successor corporation without any further act shall be the successor Trustee, if such successor corporation is otherwise eligible hereunder. 

 

	7.10	ELIGIBILITY; DISQUALIFICATION. 

 There shall at all times be a Trustee hereunder that is a corporation organized and doing business under the laws of the United States of America or of any state thereof, which Trustee (A) is
authorized under such laws to exercise corporate trustee power, (B) is subject to supervision or examination by federal or state authorities and (C) has a combined capital and surplus of at least $100,000,000 as set forth in its most
recent published annual report of condition. The Trustee shall comply with TIA § 310(b). Nothing in this Indenture shall prevent the Trustee from filing with the SEC the application referred to in the penultimate paragraph of TIA
§ 310(b). 
  

	7.11	PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.


 The Trustee shall comply with TIA § 311(a), excluding any creditor relationship listed in TIA
§ 311(b). A Trustee who has resigned or been removed shall be subject to TIA § 311(a) to the extent indicated. 
 VIII. SUBSIDIARY GUARANTEES 
  

	8.01	SUBSIDIARY GUARANTEES. 

 (A) The Securities shall be guaranteed by each of the Guarantors (each such guarantee, a “Subsidiary Guarantee”) in accordance with the provisions of this Article VIII.
Any guarantors of any Credit Facility or any Existing Notes (or of any Exchange Indebtedness or Refinancing Indebtedness in respect thereof) shall all be Guarantors of the Securities. 

(B) Subject to this Article VIII, each of the Guarantors hereby, jointly and severally, unconditionally guarantees to
each Holder of the Securities and the Trustee and Collateral Agent: (i) that the Accreted Value of, and interest on, the Securities will be promptly paid in full when due, whether at the Maturity Date, the Redemption Date, the Fundamental
Change Repurchase Date, Asset Sale Repurchase Date or other due date, and interest on the overdue Accreted Value of and interest and premium, if any, on the Securities, if any, if lawful, and that all other obligations of the Company to the Holders
or the Trustee or Collateral Agent hereunder or under the Collateral Documents will be promptly paid in full or performed, all in accordance with the terms of this Indenture; and (ii) in case of any extension of time of payment or renewal of
any Securities or any of such other obligations, that the same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at the Maturity


  
 -68-









 
Date, the Redemption Date, the Fundamental Change Repurchase Date, the Asset Sale Repurchase Date or other due date. Failing payment when due of any amount so guaranteed or any performance so
guaranteed for whatever reason, the Guarantors shall be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection. 

(C) Subject to this Article VIII, the Guarantors hereby, jointly and severally, agree that their obligations hereunder
shall be unconditional, irrespective of the validity, regularity or enforceability of the Securities or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder with respect to any provisions of this
Indenture or of the Securities, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each Guarantor
hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever
and covenants that its Subsidiary Guarantee shall not be discharged except by complete performance of the obligations contained in this Indenture and the Securities. 
 (D) If any Holder or the Trustee or Collateral Agent is required by any court or otherwise to return to the Company, any Guarantor or any custodian, trustee, liquidator or other similar official acting in
relation to either the Company or the Guarantors any amount paid by any of the foregoing to such Holder or the Trustee or Collateral Agent, then each Subsidiary Guarantee, to the extent theretofore discharged, shall be reinstated in full force and
effect. 
 (E) Each Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Trustee or
Collateral Agent or the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the
Trustee or Collateral Agent, on the other hand, (i) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article VI for the purposes of the Subsidiary Guarantees, notwithstanding any stay,
injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby and (ii) in the event of any declaration of acceleration of such obligations as provided in Article VI, such
obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantors for the purpose of the Subsidiary Guarantees. 
 (F) The Guarantors 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 Subsidiary Guarantees.
The provisions of this Section 8.01(F) shall in no respect limit the obligations and liabilities of each Guarantor to the Secured Parties and the Holders and each Guarantor shall remain liable to the Secured Parties and the
Holders for the full amount guaranteed by such Guarantor hereunder. 

  
 -69-










	8.02	GUARANTORS MAY CONSOLIDATE, ETC., ON CERTAIN TERMS.


 No Guarantor shall consolidate with, or merge with or into, or sell, transfer, lease, convey or otherwise
dispose of all or substantially all of its property or assets to another person, whether in a single transaction or series of related transactions, unless: 
 (A) immediately after giving effect to such transaction or series of related transactions, no Default or Event of Default exists; and 

(B) subject to Section 8.03, the surviving person (if not such Guarantor) or the person acquiring such property
or assets assumes all the obligations of such Guarantor under this Indenture and its Subsidiary Guarantee pursuant to a supplemental indenture in form satisfactory to the Trustee. 

Subject to Section 8.03, if there shall occur any such consolidation, merger, sale, transfer, lease, conveyance
or disposition with respect to a Guarantor, then, upon the assumption by the successor person, by supplemental indenture executed and delivered to the Trustee and satisfactory in form to the Trustee, of the Subsidiary Guarantee of such Guarantor and
the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by such Guarantor, such successor person shall succeed to and be substituted for such Guarantor with the same effect as if such successor
person had been named in this Indenture as a Guarantor. Each Subsidiary Guarantee so issued shall in all respects have the same legal rank and benefit under this Indenture and the Securities as the Subsidiary Guarantees theretofore and thereafter
issued in accordance with the terms of this Indenture as though all of such Subsidiary Guarantees had been issued at the date of the execution hereof. 
 Except as provided in Article V, and notwithstanding Section 8.02(A) and Section 8.02(B), nothing contained in this Indenture or in
any of the Securities shall prevent any sale, transfer, lease, conveyance or disposition of all or substantially all of the property or assets of a Guarantor to the Company or another Guarantor or prevent any consolidation or merger of a Guarantor
with or into the Company or another Guarantor. 
 The Company shall deliver to the Trustee prior to the consummation of the
foregoing transaction an Officers’ Certificate to the foregoing effect and an Opinion of Counsel (which may rely upon such Officers’ Certificate as to the absence of Defaults and Events of Default) stating that the proposed transaction and
such supplemental indenture will, upon consummation of the proposed transaction, comply with this Indenture. 
  

	8.03	RELEASE OF SUBSIDIARY GUARANTEES. 


The Subsidiary Guarantee of a Guarantor will be released, and any Person acquiring assets (including by way of merger or consolidation) or
Capital Stock of a Guarantor shall not be required to assume the obligations of such Guarantor: 
 (A) in connection with any
sale, transfer, lease, conveyance or disposition of all or substantially all of the property or assets of such Guarantor (including by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transaction)
the Company or a Subsidiary of the Company otherwise permitted by this Indenture; 

  
 -70-









 (B) in connection with any sale of a majority of the Capital Stock of such Guarantor to a
Person that is not (either before or after giving effect to such transaction) the Company or a Subsidiary of the Company otherwise permitted by this Indenture; or 
 (C) if the Company’s obligations under this Indenture and the Securities are discharged in accordance with the terms thereof. 
 Upon delivery by the Company to the Trustee of an Officers’ Certificate and an Opinion of Counsel to the foregoing effect, the Trustee will execute any documents reasonably requested in order to
evidence the release of the Guarantor from its obligations under its Subsidiary Guarantee. 
  

	8.04	FRAUDULENT CONVEYANCES. 

 Each Guarantor, and, by its acceptance of any Security, each Holder, hereby confirms that it is the intention of all such parties that the Subsidiary Guarantee of such Guarantor not constitute a
fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any Subsidiary Guarantee. To
effectuate the foregoing intention, the Holders and the Guarantors hereby irrevocably agree that the obligations of each Guarantor under its Subsidiary Guarantee shall be limited to the maximum amount as will, after giving effect to all other
contingent and fixed liabilities of such Guarantor that are relevant under such 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 its Subsidiary Guarantee, result in the obligations of such Guarantor under its Subsidiary Guarantee not constituting a fraudulent transfer or conveyance. 

 

	8.05	ADDITIONAL SUBSIDIARY GUARANTEES. 


If, after the Issue Date, a Person who was not theretofore a wholly owned Restricted Subsidiary of the Company becomes a wholly owned
Restricted Subsidiary of the Company, then such Person shall, within 15 days after the end of the fiscal quarter in which such Person becomes a Guarantor, execute a supplemental indenture substantially in the form of Exhibit F giving
effect to such Subsidiary Guarantee, and deliver an Opinion of Counsel stating that the proposed transaction and such supplemental indenture will, upon consummation of the proposed transaction, comply with this Indenture. 

 

	8.06	EXECUTION AND DELIVERY OF GUARANTY. 


The execution by each Guarantor of this Indenture (or a supplemental indenture) evidences the Subsidiary Guarantee of such Guarantor,
whether or not the person signing as an officer of the Guarantor still holds that office at the time of authentication of any Security. The delivery of any Security by the Trustee after authentication constitutes due delivery of the Subsidiary
Guarantee set forth in this Indenture on behalf of each Guarantor. 
 IX. SECURITY 

 

	9.01	COLLATERAL DOCUMENTS. 

 (a) The Trustee shall initially act as Collateral Agent. Whether or not so expressly stated therein, in entering into, or taking (or forbearing from) any action under or pursuant to, any Collateral
Document, the Collateral Agent shall have all of the rights, immunities, indemnities and other protections granted to it and to the Trustee under this Indenture (in addition to those that may be granted to it under the terms of any Collateral
Document or such other agreement or agreements). 

  
 -71-









 (b) In order to secure the due and punctual payment of the Accreted Value of and interest
and premium, if any, on the Securities, the Obligors have entered or will enter into the Collateral Documents to create security interests in the Collateral on a first priority basis (subject to Permitted Liens) in accordance with the terms hereof
of the Collateral Documents. In the event of a conflict between the terms of this Indenture and the Collateral Documents, the Indenture shall control. 
 The Company shall deliver to the Collateral Agent copies of all the Collateral Documents, and will do or cause to be done all such acts and things as may be reasonably required to assure and confirm to
the Collateral Agent the security interest in the Collateral contemplated hereby, by the Collateral Documents or any part thereof, as from time to time constituted, so as to render the same available for the security and benefit of this Indenture
and of the Securities secured hereby, according to the intent and purposes herein expressed. The Company shall use its commercially reasonable efforts to take any and all actions required to cause the Collateral Documents to create and maintain, as
security for the Obligations, a valid and enforceable perfected Lien and security interest in and on all of the Collateral (subject to the terms hereof and of the Collateral Documents), in favor of the Collateral Agent for the benefit of the Secured
Parties. 
 The Company shall use its commercially reasonable efforts to make all filings (including filings of continuation
statements and amendments to financing statements that may be necessary to continue the effectiveness of such financing statements) and take all other actions as are necessary or required by the Collateral Documents to maintain (at the sole cost and
expense of the Company) the security interest created by the Collateral Documents in the Collateral (other than with respect to any Collateral the security interest in which is not required to be perfected or maintained hereunder or under the
Collateral Documents) as a perfected security interest with the priority set forth in the Collateral Documents. 
 (c) Each
Holder, by accepting such Security, agrees to all of the terms and provisions of the Collateral Documents, the execution and delivery of each such Collateral Document by the Trustee and by the Collateral Agent (including the provisions providing for
the possession, use, release and foreclosure of Collateral) as the same may be in effect or may be amended from time to time in accordance with their terms and this Indenture, and authorizes and directs the Collateral Agent to enter into the
Collateral Documents and to perform its obligations and exercise its rights thereunder in accordance therewith. 
  

	9.02	OPINIONS OF COUNSEL. 

 The Company shall furnish to the Trustee and the Collateral Agent: 
 (a) at the
time when this Indenture is qualified under the TIA, Opinion(s) of Counsel to the effect that, in the opinion of such counsel, this Indenture and the grant of a Security Interest in the Collateral intended to be made by each Collateral Document and
all other instruments of further assurance or assignment have been properly recorded and filed to the extent necessary to perfect the security interests created by each such Collateral Document; 

  
 -72-









 (b) following qualification of this Indenture under the TIA, within 30 days after
February 1 in each year, Opinion(s) of Counsel, dated as of such date, either (1) to the effect that in the opinion of such counsel, such action has been taken with respect to the recordings, filings, re-recordings, and refilings of all
financing statements, continuation statements or other instruments of further assurance as is necessary to maintain the security interests of each of the Collateral Documents or (2) to the effect that, in the opinion of such counsel, no such
action is necessary to maintain such security interests. 
  

	9.03	APPLICATION OF PROCEEDS OF COLLATERAL. 


Subject to the terms of the Pledge and Security Agreement and any other Collateral Documents, upon any realization upon the Collateral,
the proceeds thereof shall be applied in accordance with Section 6.10 hereof. 
  

	9.04	ADDITIONAL COLLATERAL. 

 (A) Within 60 days following the end of each fiscal quarter, commencing with June 30, 2012, the Company shall (i) notify the Collateral Agent in writing, at the sole cost and expense of the
Company, if any Obligor acquires any assets with a Fair Market Value individually in excess of $500,000 that would constitute Collateral (other than real property, which shall be the subject of Section 9.04(B)) that are not
otherwise automatically subject to a perfected security interest under the Collateral Documents and (ii) to the extent applicable, shall within 60 days of delivery of the notice specified in the foregoing clause (i), and to the extent
required hereunder and under the Collateral Documents, execute and deliver to the Collateral Agent such security agreement supplements and other documentation (in form and scope, and covering such additional Collateral on terms consistent with the
Pledge and Security Agreement and other Collateral Documents in effect on the Issue Date, and take such additional actions as are necessary to create and fully perfect (except to the extent perfection is not required hereunder or thereunder)) in
favor of the Collateral Agent for the benefit of the Secured Parties a valid and enforceable security interest in such Collateral, which shall be free of any other Liens except for Permitted Liens. Any security interest provided pursuant this
Section 9.04(A) shall be accompanied by such Opinions of Counsel to the Company as customarily given by counsel in the relevant jurisdiction. 
 (B) If the Company or any Guarantor (i) owns, on the Issue Date, any fee interest in any land and the related improvements (including fixtures) thereon with a Fair Market Value that exceeds
$2,500,000 or (ii) acquires, after the Issue Date, any fee interest in any land and the related improvements (including fixtures) thereon with a Fair Market Value that exceeds $2,500,000 (such interests in clause (i) and
(ii) above, the “Premises”), then within 90 days of the Issue Date or the date of acquisition of such land and related improvements, as applicable, to the extent such property does not constitute Excluded Assets:

 (i) the Company or such Guarantor shall deliver to the Collateral Agent, as mortgagee, fully executed counterparts of
Mortgages, each dated as of the Issue Date, the date of acquisition of such Premises or such later date specified above, as the case may be, duly executed by the 

  
 -73-









 
Company or the applicable Guarantor, together with related Opinions of Counsel and evidence of the completion of all recordings and filings of such Mortgage as may be necessary to create a valid,
perfected Lien, subject to Permitted Liens, against the properties purported to be covered thereby; 
 (ii) the Company or such
Guarantor shall deliver to the Collateral Agent mortgagee’s title insurance policies in favor of the Collateral Agent, as mortgagee for the benefit of the Secured Parties, in an amount equal to 100% of the Fair Market Value of the Premises
purported to be covered by the related Mortgage, insuring that the interests created by the Mortgage constitute valid Liens thereon free and clear of all Liens, defects and encumbrances other than Permitted Liens; and 

(iii) the Company or such Guarantor shall deliver to the Collateral Agent, with respect to each of the covered Premises, the most recent
survey of such Premises, together with either (i) an updated survey certification in favor of the Collateral Agent from the applicable surveyor stating that, based on a visual inspection of the property and the knowledge of the surveyor, there
has been no change in the facts depicted in the survey; or (ii) an affidavit or indemnity from the Company or the applicable Guarantor, as the case may be, stating that to its knowledge, there has been no change in the facts depicted in the
survey, other than, in each case, changes that do not materially adversely affect the use by the Company or Guarantor, as applicable, of such Premises for the Company’s or such Guarantor’s business as so conducted, or intended to be
conducted, at such Premises and in each case, in form sufficient for the title insurer issuing the title policy to remove the standard survey exception from such policy and provide survey coverage to such policy. 

Notwithstanding anything herein to the contrary, the Trustee makes no representation as to the validity, adequacy or sufficiency of the
documents listed in clauses (i), (ii) or (iii) of this Section 9.04(B) and assumes no responsibility for their correctness. For the avoidance of doubt, the Company and any Guarantor shall
take all necessary steps to grant a (x) senior Lien in favor of the Collateral Trustee on all assets that are or become collateral for any Existing Notes (in respect of which, such Liens shall be expressly subordinated to the senior Lien in
favor of the Collateral Trustee securing the Obligations under this Indenture), and on all assets that are or become collateral for any Credit Facility described in clause (2) of “Permitted Indebtedness” that are not used in
calculating Borrowing Base and (y) a junior Lien in favor of the Collateral Trustee on all assets that are or become collateral for any Credit Facility described in clause (2) of “Permitted Indebtedness” that are used in
calculating Borrowing Base, or in each case of (x) and (y), any Exchange Indebtedness or Refinancing Indebtedness in respect thereof, and pursuant to one or more intercreditor agreements in accordance with Section 4.16. 

 

	9.05	RELEASE OF COLLATERAL. 

 (a) The Collateral Agent’s Liens upon the Collateral will no longer secure the Securities and Guarantees thereof outstanding under this Indenture or any other Obligations under this Indenture, and
the right of the Holders of the Securities and such Obligations to the benefits and proceeds of the Collateral Agent’s Liens on the Collateral will terminate and be automatically discharged without further action by the Trustee, the Collateral
Agent or any other Person: 
 (1) in part, as to all property subject to such Liens which has been taken by
eminent domain, condemnation or other similar circumstances; 

  
 -74-









 (2) in whole, upon: 

(A) payment in full of the Accreted Value of, accrued and unpaid interest and premium, if any, on the Securities, any
payment of all other Obligations hereunder or under any Collateral Documents; or 
 (B) satisfaction and
discharge of this Indenture as set forth in Article X hereof; or 
 (C) legal defeasance or
covenant defeasance of this Indenture as set forth in Article X hereof; 
 (3) in part, as to
any property that (A) is sold, transferred or otherwise disposed of by the Company or one of its Restricted Subsidiaries in a transaction not prohibited by this Indenture, at the time of such sale, transfer or disposition, to the extent of the
interest sold, transferred or disposed of or (B) is owned or at any time acquired by a Guarantor that has been released from its Guarantee of the Securities, concurrently with the release of such Guarantee; 

(4) in part, as to any property that constitutes all or substantially all of the Collateral securing the Securities
Obligations, with the consent of Holders of 75% in aggregate principal amount of the Securities (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, Securities); or 

(5) in part, as to any property that constitutes less than substantially all of the Collateral securing the Securities
Obligations, with the consent of Holders of a majority in aggregate principal amount of the Securities (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, Securities).

 (b) To the extent applicable and where necessary to comply with §314(c) of the TIA, the Company and each Guarantor
will furnish to the Trustee, prior to each proposed release of Collateral pursuant to the Collateral Documents and this Indenture: 
 (A) an Officers’ Certificate requesting such release; 
 (B) an Officers’
Certificate and an Opinion of Counsel to the effect that all conditions precedent provided for in this Indenture and the Collateral Documents to such release have been complied with; 

(C) where applicable, a certificate or opinion of an accountant verifying such conditions precedent that are subject to verification by
an accountant; and 
 (D) a form of such release (which release shall be in form reasonably satisfactory to the Trustee and
shall provide that the requested release is without recourse or warranty to the Trustee). 

  
 -75-









 Upon compliance by the Company or the Guarantors, as the case may be, with the conditions
precedent set forth above, and upon delivery by the Company or such Guarantor to the Trustee of an Opinion of Counsel to the effect that such conditions precedent have been complied with, the Trustee or the Collateral Agent shall promptly execute
and deliver such documents as are provided to the Trustee or the Collateral Agent to cause to be released and reconveyed to the Company, or the Guarantors, as the case may be, the released Collateral. 

(c) The release of any Collateral from the terms of the Collateral Documents will not be deemed to impair the security under this
Indenture in contravention of the provisions hereof or affect the Lien of this Indenture or the Collateral Documents if and to the extent the Collateral is released pursuant to this Indenture, the Collateral Documents or upon the termination of this
Indenture. 
  

	9.06	SUITS TO PROTECT THE COLLATERAL. 


Subject to the provisions of the Collateral Documents and without limiting the obligations of the Company to protect the security interest
of the Collateral Agent in the Collateral, the Trustee shall have the authority (but not the obligation) to direct the Collateral Agent to institute and to maintain such suits and proceedings as to prevent any impairment of the Collateral by any
acts which may be unlawful or in violation of any of the Collateral Documents or this Indenture, and such suits and proceedings to preserve or protect its interests and the interests of any Holder in the Collateral (including suits or proceedings to
restrain the enforcement of or compliance with any legislative or other governmental enactment, rule or order that may be unconstitutional or otherwise invalid if the enforcement of, or compliance with, such enactment, rule or order would impair the
Liens or be prejudicial to the interests of the Holders). 
  

	9.07	CERTAIN TIA REQUIREMENTS. 

 Following the qualification of this Indenture under the TIA, to the extent applicable, and in addition to any other requirements under this Indenture, the Company will cause §313(b) of the TIA
(relating to reports) and §314(d) of the TIA (relating to the release of property or securities from the Liens or relating to the substitution for such Liens of any property or securities to be subjected to the Liens) to be complied with
and will furnish to the Trustee, prior to each proposed release of Collateral pursuant to this Indenture and the Collateral Documents, all documents required by §314(d) of the TIA. 

 

	9.08	USE OF COLLATERAL. 

 Subject to the terms of this Indenture and the Collateral Documents, the Company and each Guarantor shall have the right to remain in possession and retain exclusive control of the Collateral, to freely
operate the Collateral and to collect, invest and dispose of any income therefrom. 
 X. DISCHARGE AND DEFEASANCE OF
INDENTURE 
  

	10.01 	LEGAL DEFEASANCE AND COVENANT DEFEASANCE. 


(A) The Company may, at its option and at any time, elect to have either Section 10.01(B) or
Section 10.01(C) apply to the outstanding Securities upon compliance with the applicable conditions set forth in Section 10.01(D). 

  
 -76-









 (B) Upon the Company’s exercise under Section 10.01(A) of the
option applicable to this Section 10.01(B), the Company and the Guarantors shall be deemed to have been released and discharged from their obligations with respect to the outstanding Securities on the date the applicable conditions set
forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, such Legal Defeasance means that the Company shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding
Securities, which shall thereafter be deemed to be outstanding only for the purposes of the Sections and matters under this Indenture referred to in clauses (i) and (ii) below, and to have satisfied all their other obligations under
such Securities and this Indenture insofar as such Securities are concerned, except for the following which shall survive until otherwise terminated or discharged hereunder: (i) the rights of Holders of outstanding Securities to receive solely
from the Trust Fund described in Section 10.01(D) and as more fully set forth in Section 10.01(D) payments in respect of the Accreted Value of, and premium, if any, interest on such Securities when
such payments are due and (ii) Sections 2.02, 2.03, 2.04, 2.05, 2.06, 2.07, 2.08, 2.10, 2.15,
2.16, 2.17, 3.05, 3.06, 4.01, 4.2, 4.05, 7.07, 7.08 and 9.01(a) and Article X. The Company may exercise
its option under this Section 10.01(B) notwithstanding the prior exercise of its option under Section 10.01(C) below with respect to the Securities. 

(C) Upon the Company’s exercise, under Section 10.01(A) of the option applicable to this
Section 10.01(C), the Company and its Restricted Subsidiaries shall be released and discharged from their obligations under any covenant contained in Section 5.01(C), Section 4.03 and
Sections 4.08 through 4.27, inclusive, with respect to the outstanding Securities on and after the date the conditions set forth below are satisfied (a “Covenant Defeasance”), and the
Securities shall thereafter be deemed to be not “outstanding” for the purpose of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to
be deemed “outstanding” for all other purposes hereunder. For this purpose, such Covenant Defeasance means that, with respect to the outstanding Securities, the Company may omit to comply with and shall have no liability in respect of any
term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any
other document and such omission to comply shall not constitute a Default or an Event of Default, but, except as specified above, the remainder of this Indenture and such Securities shall be unaffected thereby. 

(D) The following shall be the conditions to application of either Section 10.01(B) or
Section 10.01(C) to the outstanding Securities: 
 (i) the Company shall have irrevocably deposited
with the Trustee, in trust, for the benefit of the Holders, U.S. Legal Tender or non-callable U.S. Government Obligations or a combination thereof (collectively, the “Trust Funds”), in such amounts and at such times as are
sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the Accreted Value of, and premium, if any, and interest on the outstanding Securities on the stated dates for payment or Redemption, as the case
may be; 
 (ii) in the case of Legal Defeasance, the Company shall have delivered to the Trustee an Opinion of Counsel that the
Company has received from, or there has been published by, the Internal Revenue Service a ruling, or since the Issue Date, there has been a change in the applicable federal income tax law, in either case to the effect that the Holders and beneficial
owners will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case
if such Legal Defeasance had not occurred; 

  
 -77-









 (iii) in the case of Covenant Defeasance, the Company shall have delivered to the Trustee an
Opinion of Counsel that the Holders and beneficial owners will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same
manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; 
 (iv) no Default or
Event of Default shall have occurred and be continuing on the date of such deposit pursuant to Section 10.01(D)(i) (except such Default or Event of Default resulting the borrowing of funds required to effect such
deposit); 
 (v) such Legal Defeasance or Covenant Defeasance shall not result in a breach of, or constitute a default under any
other material agreement or instrument to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound; 
 (vi) the Company shall have delivered to the Trustee an Officers’ Certificate stating that the deposit was not made by the Company with the intent of preferring the Holders over any other creditors
of the Company or with the intent of defeating, hindering, delaying or defrauding any other creditors of the Company or others; 

(vii) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all
conditions precedent provided for or relating to the Legal Defeasance or the Covenant Defeasance, as applicable, have been complied with; and 
 (viii) the Trustee shall have received all compensation due to it in all capacities hereunder or in any related document. 
  

	10.02 	TERMINATION OF THE OBLIGATIONS OF THE COMPANY;
SATISFACTION AND DISCHARGE. 

 This Indenture shall cease to be of
further effect if (a) either (i) all outstanding Securities (other than Securities replaced pursuant to Section 2.07 hereof) have been delivered to the Trustee for cancellation or (ii) all outstanding
Securities have become due and payable at their scheduled maturity or upon Redemption, Repurchase Upon Asset Sale or Repurchase Upon Fundamental Change, or will become due and payable at maturity within one year or will be redeemed within one year
on terms reasonably acceptable to the Trustee and in any case the Company has irrevocably deposited with the Trustee or the Paying Agent (if the Paying Agent is not the Company or any of its Affiliates) Trust Funds in such amounts and at such times
as are sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the Accreted Value of, and premium, if any, and interest on the outstanding Securities on the stated dates for payment or Redemption, as the
case may be, sufficient to pay all amounts due and owing on all outstanding Securities (other than Securities replaced pursuant to Section 2.07 hereof) on the Maturity Date or a Redemption Date, Asset Sale Repurchase Date
or Fundamental Change Repurchase Date, as the case may be; (b) the Company has paid to the Trustee all other sums payable hereunder by the Company; (c) no Default or Event of Default with respect to the Securities shall exist on the date
of such deposit; (d) such deposit will not result in a breach or violation of, or constitute a Default or Event of Default under, this Indenture (other than as a result of the 

  
 -78-









 
borrowing to fund such deposit) or any other agreement or instrument to which the Company is a party or by which it is bound; and (e) the Company has delivered to the Trustee an

deposit had occurred pursuant to Sections 10.01, 10.02 and 10.03; provided, however, that if the Company has made any payment of amounts due with respect to any Securities because of the reinstatement of its obligations, then the Company

	11.02	WITH CONSENT OF HOLDERS. 


The Company, and the Guarantors, and the Trustee and Collateral Agent, if applicable, may amend or supplement this Indenture, the
Securities or Collateral Documents without notice to any Securityholder but with the written consent of the Holders of at least a majority in aggregate principal amount of the outstanding Securities. Subject to

Default), except to increase the percentage required for modification or waiver or to provide for the consent of each affected Holder. 
 In addition, without the consent of the Holders of at least 75% of the aggregate principal amount of the outstanding Securities, an amendment, supplement or waiver, including a waiver pursuant to
Section 6.04, may not permit the release of all or substantially all of the Collateral, other than in accordance with the terms of the Collateral Documents or this Indenture. 

Promptly after an amendment, supplement or waiver under this Section 11.02 becomes effective, the Company shall
mail, or cause to be mailed, to Securityholders a notice briefly describing such amendment, supplement or waiver. Any failure of the Company to mail such notice shall not in any way impair or affect the validity of such amendment, supplement or
waiver. 
 It shall not be necessary for the consent of the Holders under this Section 11.02 to
approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof. 
  

	11.03	COMPLIANCE WITH TRUST INDENTURE ACT. 


If this Indenture is qualified under the TIA, every amendment, waiver or supplement to this Indenture or the Securities shall comply with
the TIA as then in effect. 

  
 -81-










	11.04 	REVOCATION AND EFFECT OF CONSENTS. 


Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder is a continuing consent by the Holder and every
subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent is not made on any Security. However, any such Holder or subsequent Holder may revoke the
consent as to its Security or portion of a Security if the Trustee receives the notice of revocation before the date the amendment, supplement or waiver becomes effective. An amendment, supplement or waiver becomes effective in accordance with its
terms and thereafter binds every Holder. 
 After an amendment, supplement or waiver becomes effective with respect to the
Securities, it shall bind every subsequent Holder. 
  

	11.05 	NOTATION ON OR EXCHANGE OF SECURITIES. 


If an amendment, supplement or waiver changes the terms of a Security, the Trustee may require the Holder of the Security to deliver it to
the Trustee. The Trustee may place an appropriate notation on the Security as directed and prepared by the Company about the changed terms and return it to the Holder. Alternatively, if the Company so determines, the Company in exchange for the
Security shall issue and, upon receipt of a Company Order, the Trustee shall authenticate a new Security that reflects the changed terms. Failure to make the appropriate notation or to issue a new security shall not affect the validity of such
amendment. 
  

	11.06 	TRUSTEE PROTECTED. 

 The Trustee shall sign any amendment, supplemental indenture or waiver authorized pursuant to this Article XI; provided, however, that the Trustee need not sign any amendment,
supplement or waiver authorized pursuant to this Article XI that adversely affects the Trustee’s rights, duties, liabilities or immunities. The Trustee shall be entitled to receive and conclusively rely upon an Opinion of
Counsel as to legal matters and an Officers’ Certificate as to factual matters that any supplemental indenture, amendment or waiver is permitted or authorized pursuant to this Indenture and that all conditions precedent thereto have been
satisfied. 
 XII. MISCELLANEOUS

to other Holders.

addressee receives it. 
 If the Company mails a notice or communication to Holders, it shall mail a copy to the Trustee and
