Subsidiary or (b) assumed in connection with acquisitions of properties or assets from such Person. Acquired Indebtedness shall be deemed to be incurred on the date the acquired Person becomes a Restricted Subsidiary or the date of the related
acquisition of properties or assets from such Person. 
  
 “Additional Interest” means all additional interest then owing pursuant to a Registration Rights Agreement. Unless the context indicates otherwise, all references to “interest” in this Indenture or the Notes shall
be deemed to include any Additional Interest. 
  
 “Affiliate” of any specified Person means an “affiliate” of such Person, as such term is defined for purposes of Rule 144 under the Securities Act. 
  
 “Agent” means any Registrar or Paying Agent. 
  
 “Applicable Procedures” means, with respect to any transfer or exchange of beneficial interests in a Global Note, the
rules and procedures of the Depository, Euroclear or Clearstream that apply to such transfer or exchange. 
  
 “Asset Sale” means (a) the sale, lease, conveyance or other disposition (a “disposition”) of any properties, assets or rights (including,
without limitation, by way of a sale and leaseback), excluding dispositions in the ordinary course of business (provided that the disposition of all or 
  

 - 1 - 

 substantially all of the properties or assets of the Company and its Restricted Subsidiaries taken as a whole will be subject to
Sections 4.15 and 5.01 of this Indenture and not to the provisions of Section 4.10 hereof), (b) the issue or sale by the Company or any of its Restricted Subsidiaries of Equity Interests of any of the Company’s Subsidiaries, and (c) any Event
of Loss, whether in the case of clause (a), (b) or (c), in a single transaction or a series of related transactions, provided that such transaction or series of related transactions (i) involves properties, assets or rights having a fair market
value in excess of $5,000,000 or (ii) results in the payment of net proceeds (including insurance proceeds from an Event of Loss) in excess of $5,000,000. Notwithstanding the foregoing provisions of this definition, the following transactions will

Person, provided that the fair market value of the properties or assets traded or exchanged by the Company or such Restricted Subsidiary (together with any cash or Cash Equivalents) is reasonably equivalent to the fair market value of the properties
or assets (together with any cash or Cash Equivalents) to be received by the Company or such Restricted Subsidiary. The fair market value of any non cash proceeds of a disposition of properties or assets and of any properties or assets referred to
in the foregoing clauses (E) and (F) of this definition shall be determined in the manner contemplated in the definition of the term “fair market value,” the results of which determination shall be set forth in an Officers’
Certificate delivered to the Trustee. 
  
 “Attributable
Indebtedness” in respect of a sale-and-leaseback transaction means, at the time of determination, the present value (discounted at the rate of interest implicit in such transaction, determined in accordance with GAAP) of the obligation of
the lessee for net rental payments during the remaining term of the lease included in such sale-and-lease-back transaction (including any period for which such lease has been extended or may, at the option of the lessor, be extended). As used in the

accordance with Section 2.02 hereof, authenticate and deliver Definitive Notes in an aggregate principal amount equal to the principal amount of the Global Notes in exchange for such Global Notes. Definitive Notes issued in exchange for beneficial
interests in the Global Notes pursuant to this Section 2.06(e) shall be registered in such names and in such authorized denominations as the Depository, pursuant to instructions from its direct or Indirect Participants or otherwise, shall instruct

 Section 2.07 REPLACEMENT NOTES. 
  
 If any mutilated Note is surrendered to the Trustee or the Company, or the Trustee receives evidence to its satisfaction of the
destruction, loss or theft of any Note, the Company shall issue and the Trustee, upon the written order of the Company signed by one Officer of the Company, shall authenticate a replacement Note (accompanied by a notation of the Subsidiary
Guarantees duly endorsed by the Guarantors) if the Trustee’s requirements are met. If required by the Trustee and the Company, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Company to
protect the Company, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Company may charge for its expenses in replacing a Note. If, after the delivery of such replacement Note, a
protected purchaser of the original Note in lieu of which such replacement Note was issued presents for payment or registration such original Note, the Trustee shall be entitled to recover such replacement Note from the Person to whom it was
delivered or any Person taking therefrom, except a protected purchaser, and shall be entitled to recover upon the security or indemnity provided therefor to the extent of any loss, damage, cost or expense incurred by the Company, the Trustee, any
Agent and any authenticating agent in connection therewith.

Except as set forth in Section 2.09 hereof, a Note does not cease to be outstanding because the Company, any Subsidiary of the Company or an Affiliate of the Company or any Subsidiary of the Company holds the Note. 
  
 If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding
unless the Trustee receives proof satisfactory to it that the replaced Note is held by a protected purchaser. 
  
 If the entire principal of, and premium, if any, and interest on, any Note are considered paid under Section 4.01 hereof, it ceases to be outstanding and interest
on it ceases to accrue as of the date of such payment. 
  
 Section 2.09
TREASURY NOTES. 
  
 In determining
whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Company, a Subsidiary of the Company or an Affiliate, shall be considered as though not outstanding, except that for
the purposes of 
  

 - 31 - 

 determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes that a Trustee
knows are so owned shall be so disregarded. Notwithstanding the foregoing, Notes that the Company, a Subsidiary of the Company or an Affiliate offers to purchase or acquires pursuant to an offer, exchange offer, tender offer or otherwise shall not

surrendered for registration of transfer, exchange, payment, replacement or cancellation and, at the request of the Company, shall destroy cancelled Notes (subject to the record retention requirements of the Exchange Act). Certification of the
destruction of all cancelled Notes shall be delivered to the Company upon its written request. The Company may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation, other than as
contemplated by the Exchange Offer. 
  
 Section 2.12 DEFAULTED
INTEREST.

provided in the Notes and in Section 4.01 hereof. The Company shall notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Company shall fix or cause to be fixed

Company (or, upon the written request of the Company, the Trustee in the name and at the expense of the Company) shall mail or cause to be mailed to Holders a notice that states the special record date, the related payment date and the amount of
such interest to be paid.

failure of the Company to comply with the preceding paragraph, interest shall be paid on the unpaid principal and any premium, from the redemption date until such principal and any premium are paid, and to the extent lawful on any interest not paid

shall be required to surrender the Note, with the form entitled “Option of Holder to Elect Purchase” on the reverse of the Note completed, to the Company or a Paying Agent at the address specified in the notice before the termination of
the Offer Period; 
  
 (g) that Holders shall be entitled to withdraw their
election if the Company or the Paying Agent, as the case may be, receives, not later than the expiration of the Offer Period, a telegram, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Note the
Holder delivered for purchase and a statement that such Holder is withdrawing his election to have such Note purchased; 
  
 (h) that, if the aggregate principal amount of Notes surrendered by Holders exceeds the Offer Amount, the Trustee shall select the Notes to be purchased on a pro
rata basis (with such adjustments as may be deemed appropriate by the Trustee so that only Notes in minimum denominations of $2,000, and integral multiples of $1,000 in excess thereof, shall be purchased); and 
  
 (i) that Holders whose Notes were purchased only in part shall be issued new Notes
equal in principal amount to the unpurchased portion of the Notes surrendered (or transferred by book-entry transfer). 
  
 If any of the Notes subject to an Asset Sale Offer is in the form of a Global Note, then the Company shall modify such notice to the extent necessary to accord with
the procedures of the Depository applicable to repurchases. 
  
 On or before
the Purchase Date, the Company shall, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Offer Amount of Notes or portions thereof tendered pursuant to the Asset Sale Offer, or if less than the Offer
Amount has been tendered, all Notes tendered, and shall deliver to the Trustee an Officers’ Certificate stating that such Notes or portions thereof were accepted for payment by the Company in accordance with the terms of this Section 3.09. The
Company or the Paying Agent, as the case may be, shall promptly (but in any case not later than three days after the Purchase Date) mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder
and accepted by the Company for purchase, and the Company shall promptly issue a new Note, and the Trustee shall authenticate and mail or deliver such new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note
surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Company to the Holder thereof. The Company shall publicly announce the results of the Asset Sale Offer on the Purchase Date.

 Other than as specifically provided in this Section 3.09, any purchase pursuant to this Section 3.09 shall be made

 (b) So long as not contrary to the then current recommendations of the American Institute of Certified Public Accountants, the year-end financial statements
delivered pursuant to Section 4.03(a) above shall be accompanied by a written statement of the Company’s independent public accountants (who shall be a firm of established national reputation) that in making the examination necessary for
certification of such financial statements, nothing has come to their attention that 
  

 - 39 - 

 would lead them to believe that the Company has violated any provisions of Article 4 or Article 5 hereof or, if any such violation
has occurred, specifying the nature and period of existence thereof, it being understood that such accountants shall not be liable directly or indirectly to any Person for any failure to obtain knowledge of any such violation. 
  
 (c) The Company shall, so long as any of the Notes are outstanding, deliver to the

Notes. 
  
 Section 4.06 STAY, EXTENSION AND
USURY LAWS. 
  
 The Company covenants (to
the extent that it may lawfully do so) that it shall 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,
that may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it shall not, by resort to any such
law, hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law has been enacted. 
  
 Section 4.07 RESTRICTED PAYMENTS. 
  
 The Company shall not, and shall not permit any of its Restricted Subsidiaries to,

connection with any merger or consolidation involving the Company) or to the direct or indirect holders of the Company’s Equity Interests in their capacity as such (other than dividends or distributions payable in Equity Interests (other than
Disqualified Stock) of the Company); (ii) purchase, redeem or otherwise acquire or retire for value (including, without limitation, in connection with any merger or consolidation involving the Company) any Equity Interests of the Company or any of
its Restricted Subsidiaries (other than any such Equity Interests owned by the Company or any Wholly Owned Restricted Subsidiary of the Company); (iii) make any payment on or with respect to, or purchase, redeem, defease or otherwise acquire or
retire for value, any Indebtedness that is subordinated in right of payment to the Notes or the Subsidiary Guarantees, as the case may be, except a payment of interest or principal at Stated Maturity; or (iv) make any Restricted Investment (all such
payments and other actions set forth in clauses (i) through (iv) above 
  

 - 40 - 

 being collectively referred to as “Restricted Payments”), unless, at the time of and after giving effect to such
Restricted Payment: 
  
 (a) no Default or Event of Default shall have
occurred and be continuing or would occur as a consequence thereof; 
  
 (b)
the Company would, at the time of such Restricted Payment and after giving pro forma effect thereto as if such Restricted Payment had been made at the beginning of the applicable four-quarter period, have been permitted to incur at least
$1.00 of additional Indebtedness pursuant to the Consolidated Interest Coverage Ratio test set forth in Section 4.09 hereof; and 
  
 (c) such Restricted Payment, together with the aggregate amount of all other Restricted Payments made by the Company and its Restricted Subsidiaries after the Issue
Date (excluding Restricted Payments permitted by clauses (b), (c), (d), (f), (g) and (h), but including Restricted Payments permitted by clauses (a) and (e) of the next succeeding paragraph), is less than the sum of the following: (A) 50% of the
cumulative Consolidated Net Income of the Company for the period (taken as one accounting period) from January 1, 2004 to the end of the Company’s most recently ended fiscal quarter for which internal financial statements are available at the
time of such Restricted Payment (or, if such Consolidated Net Income for such period is a deficit, less 100% of such deficit), plus (B) subject to clause (b) of the next succeeding paragraph, 100% of the aggregate net cash proceeds, and the fair
market value of any property other than cash, received by the Company since January 1, 2004 from the issue or sale of Equity Interests of the Company (other than Disqualified Stock) or of Disqualified Stock or debt securities of the Company that
have been converted into, or exchanged for, such Equity Interests (other than any such Equity Interests, Disqualified Stock or convertible debt securities sold to a Restricted Subsidiary of the Company and other than Disqualified Stock or
convertible debt securities that have been converted into, or exchanged for, Disqualified Stock), plus (C) to the extent that any Restricted Investment that was made after the Issue Date is sold for cash or otherwise liquidated or repaid for cash,
the lesser of (1) cash return of capital with respect to such Restricted Investment (less the cost of disposition, if any) and (2) the initial amount of such Restricted Investment plus (D) in the event that any Unrestricted Subsidiary is
redesignated as a Restricted Subsidiary, the lesser of (1) an amount equal to the fair market value of the Investments previously made by the Company and its Restricted Subsidiaries in such Subsidiary as of the date of redesignation and (2) the
amount of such Investments plus (E) $20,000,000. 
  
 The foregoing
provisions will not prohibit any of the following: (a) the payment of any dividend within 60 days after the date of declaration thereof, if at said date of declaration such payment would have complied with the provisions of this Indenture; (b) the
redemption, repurchase, retirement, defeasance or other acquisition of any subordinated Indebtedness of the Company or any Guarantor or any Equity Interests of the Company or any of its Restricted Subsidiaries in exchange for, or out of the net cash
proceeds of the substantially concurrent sale (other than to a Restricted Subsidiary of the Company) of, other Equity Interests of the Company (other than any Disqualified Stock), provided that the amount of any such net cash proceeds that are
utilized for any such redemption, repurchase, retirement, defeasance or other acquisition shall be excluded from clause (c)(B) of the preceding paragraph; (c) the defeasance, redemption, repurchase, retirement or other 
  

 - 41 - 

 acquisition of subordinated Indebtedness of the Company or any Guarantor with the net cash proceeds from an incurrence of, or in
exchange for, Permitted Refinancing Indebtedness; (d) the payment of any dividend or distribution by a Restricted Subsidiary of the Company to the Company or any Wholly Owned Restricted Subsidiary of the Company; (e) so long as no Default or Event
of Default has occurred and is continuing, the repurchase, redemption or other acquisition or retirement for value of any Equity Interests of the Company or any Restricted Subsidiary of the Company held by any employee of the Company or any of its
Restricted Subsidiaries, provided that the aggregate price paid for all such repurchased, redeemed, acquired or retired Equity Interests shall not exceed $500,000 in any calendar year; (f) the acquisition of Equity Interests by the Company in
connection with the exercise of stock options or stock appreciation rights by way of cashless exercise or in connection with the satisfaction of withholding tax obligations; (g) in connection with an acquisition by the Company or by any of its
Restricted Subsidiaries, the return to the Company or any of its Restricted Subsidiaries of Equity Interests of the Company or any of its Restricted Subsidiaries constituting a portion of the purchase price consideration in settlement of
indemnification claims; and (h) the purchase by the Company of fractional shares of Equity Interests arising out of stock dividends, splits or combinations or business combinations;. 
  
 The Board of Directors may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if such designation would not cause a
Default. For purposes of making such designation, all outstanding Investments by the Company and its Restricted Subsidiaries (except to the extent repaid in cash) in the Subsidiary so designated shall be deemed to be Restricted Payments at the time
of such designation (except to the extent they qualify as Permitted Investments), in an amount equal to the greater of (a) the net book value of such Investments at the time of such designation and (b) the fair market value of such Investments at
the time of such designation. Such designation shall only be permitted if such Restricted Payments would be permitted at such time and if such Restricted Subsidiary otherwise meets the definition of “Unrestricted Subsidiary.”

  
 The Board of Directors may also redesignate any Unrestricted Subsidiary
to be a Restricted Subsidiary if such redesignation complies with the requirements described in the definition of “Unrestricted Subsidiary.” If the aggregate amount of all Restricted Payments calculated for purposes of the first
paragraph of this Section 4.07 includes an Investment in an Unrestricted Subsidiary that subsequently becomes a Restricted Subsidiary pursuant to the terms of this paragraph, then the aggregate amount of such Restricted Payments shall be reduced by
the lesser of (a) an amount equal to the fair market value of the Investments previously made by the Company and its Restricted Subsidiaries in such Unrestricted Subsidiary at the time it becomes a Restricted Subsidiary and (b) the amount of such
Investments. 
  
 Any designation or redesignation of a Subsidiary shall be
evidenced to the Trustee by filing with the Trustee a Board Resolution giving effect to such action and evidencing the valuation of any Investment relating thereto (as determined in good faith by the Board of Directors) and an Officers’
Certificate certifying that such action complied with the terms of the definition of “Unrestricted Subsidiary” set forth in this Indenture and with this Section 4.07. 
  
 The amount of all Restricted Payments (other than cash) shall be the fair market value on the date of the Restricted Payment of the
asset(s) or securities proposed to be transferred or issued by the 
  

 - 42 - 

 Company or such Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment. The fair market value of any
non-cash Restricted Payment shall be determined in the manner contemplated by the definition of the term “fair market value,” and the results of such determination shall be evidenced by an Officers’ Certificate delivered to the
Trustee. Not later than the date of making any Restricted Payment (other than a Restricted Payment permitted by clause (b), (c), (d), (f), (g) or (h) of the second full paragraph of this Section 4.07), the Company shall deliver to the Trustee an
Officers’ Certificate stating that such Restricted Payment is permitted and setting forth the basis upon which the calculations required by this Section 4.07 were computed. 
  
 Section 4.08 DIVIDEND AND OTHER PAYMENT RESTRICTIONS
AFFECTING SUBSIDIARIES. 
  
 The Company
shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to exist or become effective any encumbrance or restriction on the ability of any Restricted Subsidiary to do any of
the following: (a)(i) pay dividends or make any other distributions to the Company or any of its Restricted Subsidiaries on its Capital Stock or (ii) pay any Indebtedness owed to the Company or any of its Restricted Subsidiaries; (b) make loans or
advances to the Company or any of its Restricted Subsidiaries or (c) transfer any of its properties or assets to the Company or any of its Restricted Subsidiaries, except for such encumbrances or restrictions existing under or by reason of (1) the
Credit Facility or Existing Indebtedness, each as in effect on the Issue Date, (2) this Indenture, the Notes and the Subsidiary Guarantees, (3) applicable law, (4) any instrument governing Indebtedness or Capital Stock of a Person acquired by the
Company or any of its Restricted Subsidiaries as in effect at the time of such acquisition (except to the extent such Indebtedness was incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not
applicable to any Person or the assets of any Person, other than the Person, or the assets of the Person, so acquired, provided that, in the case of Indebtedness, such Indebtedness was permitted by the terms of the Indenture to be incurred, (5) by
reason of customary non-assignment provisions in leases entered into in the ordinary course of business and consistent with past practices, (6) by reason of customary provisions restricting the transfer of copyrighted or patented materials
consistent with industry practice, (7) purchase money obligations for property acquired in the ordinary course of business that impose restrictions of the nature described in clause (c) above on the property so acquired, (8) customary provisions in
bona fide contracts for the sale of properties or assets, (9) Permitted Refinancing Indebtedness with respect to any Indebtedness referred to in clauses (1), (2) and (4) above, provided that the restrictions referred to in this Section 4.08 that are
contained in the agreements governing such Permitted Refinancing Indebtedness are not materially more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced or (10) provisions with respect
to the disposition or distribution of assets in joint venture agreements, asset sale agreements, stock sale agreements and other similar agreements entered into in the ordinary course of business. 
  
 Section 4.09 INCURRENCE OF INDEBTEDNESS
AND ISSUANCE OF DISQUALIFIED STOCK. 
  
 The Company shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise
become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur” or an “incurrence”) any Indebtedness 
  

 - 43 - 

 (including, without limitation, Acquired Indebtedness) and the Company shall not issue any Disqualified Stock and shall not permit
any of its Restricted Subsidiaries to issue any Disqualified Stock; provided, however, that the Company and its Restricted Subsidiaries may incur Indebtedness, and the Company may issue Disqualified Stock, in each case if the Consolidated
Interest Coverage Ratio for the Company’s most recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such additional Indebtedness is incurred or such Disqualified
Stock is issued would have been at least 2.0 to 1.0 at the time such additional Indebtedness is incurred or such Disqualified Stock is issued (such time being called the “Incurrence Time”), in each case as determined on a pro
forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness or Disqualified Stock had been issued or incurred, as the case may be, at the beginning of such four-quarter period.

  
 The foregoing provisions shall not apply to the incurrence by the
Company or any of its Restricted Subsidiaries of any of the following Indebtedness: 
  
 (a) Indebtedness under the Credit Facility in an aggregate principal amount at any one time outstanding not to exceed the greater of (1) $75,000,000 and (2) 20% of the Company’s Consolidated Net Tangible Assets determined
as of the end of the Company’s most recently completed fiscal quarter for which internal financial statements are available; 
  
 (b) Existing Indebtedness; 
  
 (c) Hedging Obligations; 
  
 (d) Indebtedness represented by the Original Notes, any Series B Notes issued in exchange for Series A Notes pursuant to an Exchange Offer or the Subsidiary
Guarantees; 
  
 (e) intercompany Indebtedness between or among the Company
and any of its Wholly Owned Restricted Subsidiaries, provided that any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the Company or a Wholly Owned Restricted Subsidiary of
the Company, or any sale or other transfer of any such Indebtedness to a Person that is neither the Company nor a Wholly Owned Restricted Subsidiary of the Company, shall be deemed, in each case, to constitute an incurrence of such Indebtedness by
the Company or such Restricted Subsidiary, as the case may be, as of the date of such issuance, sale or other transfer that is not permitted by this clause (e); 
  

(f) Indebtedness in respect of bid, performance or surety bonds issued for the account of the Company or any Restricted Subsidiary thereof in the ordinary course
of business, including guarantees or obligations of the Company or any Restricted Subsidiary thereof with respect to letters of credit supporting such bid, performance or surety obligations (in each case other than for an obligation for money
borrowed); 
  
 (g) the guarantee by the Company of Indebtedness of any of
its Restricted Subsidiaries or by any Restricted Subsidiary of Indebtedness of the Company or another Restricted Subsidiary, in each case, that was permitted to be incurred by another provision of this Section 4.09; 
  

 - 44 - 

 (h) Permitted Refinancing Indebtedness incurred in exchange for, or the net proceeds of which are used to extend,
refinance, renew, replace, defease or refund Indebtedness incurred pursuant to the first paragraph and clause (b), (d) or (h) of the second paragraph of this Section 4.09; and 
  
 (i) any additional Indebtedness in an aggregate principal amount not in excess of $25,000,000 at any one time outstanding. 

 
 The Company shall not, and shall not permit any Guarantor to, directly or
indirectly, incur any Indebtedness which by its terms (or by the terms of any agreement governing such Indebtedness) is subordinated to any other Indebtedness of the Company or of such Guarantor, as the case may be, unless such Indebtedness is also
by its terms (or by the terms of any agreement governing such Indebtedness) made expressly subordinate to the Notes or the Subsidiary Guarantee of such Guarantor, as the case may be, to the same extent and in the same manner as such Indebtedness is
subordinated pursuant to subordination provisions that are most favorable to the holders of any other Indebtedness of the Company or of such Guarantor, as the case may be; provided, however, that no Indebtedness shall be deemed to be
contractually subordinated in right of payment to any other Indebtedness solely by virtue of being unsecured. 
  
 For purposes of determining compliance with this Section 4.09, in the event that an item of proposed Indebtedness meets the criteria of more than one of the
categories of Indebtedness described in clauses (a) through (i) of the second paragraph, or is entitled to be incurred pursuant to the first paragraph, of this Section 4.09, the Company shall be permitted to classify such item of Indebtedness on the
date of its incurrence, or later reclassify all or a portion of such item of Indebtedness, in any manner that complies with this Section 4.09, and such item of Indebtedness will be treated as having been incurred pursuant to such category.

  
 Section 4.10 ASSET SALES. 
  
 The Company shall not, and shall not permit any of its Restricted Subsidiaries to,
consummate an Asset Sale (excluding for this purpose an Event of Loss) unless (a) the Company or such Restricted Subsidiary, as the case may be, receives consideration at the time of such Asset Sale at least equal to the fair market value (as
determined in accordance with the definition of such term, the results of which determination shall be set forth in an Officers’ Certificate delivered to the Trustee) of the properties, assets, rights or Equity Interests issued or sold or
otherwise disposed of and (b) at least 75% of the consideration therefor received by the Company or such Restricted Subsidiary is in the form of cash or Cash Equivalents; provided, however, that the amount of (i) any liabilities (as shown on
the Company’s or such Restricted Subsidiary’s most recent balance sheet) of the Company or such Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Subsidiary
Guarantee) that are assumed by the transferee of any such assets, properties, rights or Equity Interests pursuant to a customary novation agreement that releases the Company or such Restricted Subsidiary from further liability, (ii) Liquid
Securities and (iii) any securities, notes or other obligations received by the Company or such Restricted Subsidiary from such transferee that are converted within 180 days by the Company or such Restricted Subsidiary into cash (to the extent of
the cash received in that conversion) shall each be deemed to be Cash Equivalents for purposes of this Section 4.10. 
  

 - 45 - 

 Within 365 days after the receipt of any Net Proceeds from an Asset Sale (including, without limitation, any Event
of Loss), the Company or any such Restricted Subsidiary may apply such Net Proceeds to (a) permanently repay all or any portion of the principal of any secured Indebtedness (to the extent of the fair value of the assets collateralizing such
Indebtedness, as determined by the Board of Directors) or (b) acquire (including by way of a purchase of assets or stock, merger, consolidation or otherwise) Productive Assets, provided that if the Company or such Restricted Subsidiary enters into a
binding agreement to acquire such Productive Assets within such 365-day period, but the consummation of the transactions under such agreement has not occurred within such 365-day period, and the agreement has not been terminated, then the 365-day
period will be extended to 18 months to permit such consummation; provided further, however, if such consummation does not occur, or such agreement is terminated within such 18-month period, then the Company may apply, or cause such
Restricted Subsidiary to apply, within 90 days after the end of the 18-month period or the effective date of such termination, whichever is earlier, such Net Proceeds as provided in clauses (a) and (b) of this paragraph. Pending the final
application of any such Net Proceeds, the Company or any such Restricted Subsidiary may temporarily reduce outstanding revolving credit borrowings, including borrowings under the Credit Facility, or otherwise invest such Net Proceeds in any manner
that is not prohibited by this Indenture. Any Net Proceeds from Asset Sales that are not applied or invested as provided in clauses (a) and (b) of this paragraph shall be deemed to constitute “Excess Proceeds.” 
  
 Within 30 days of each date on which the aggregate amount of Excess Proceeds exceeds
$20,000,000, the Company shall commence an Asset Sale Offer pursuant to Section 3.09 hereof to purchase the maximum principal amount of Notes that may be purchased out of Excess Proceeds at an offer price in cash in an amount equal to 100% of the
principal amount thereof, plus accrued and unpaid interest, if any, thereon, to the date of purchase, in accordance with the procedures set forth in Section 3.09 hereof; provided, however, that, if the Company is required to apply such Excess
Proceeds to purchase, or to offer to purchase, any Pari Passu Indebtedness, the Company shall only be required to offer to purchase the maximum principal amount of Notes that may be purchased out of the amount of such Excess Proceeds
multiplied by a fraction, the numerator of which is the aggregate principal amount of Notes outstanding and the denominator of which is the aggregate principal amount of Notes outstanding plus the aggregate principal amount of Pari Passu
Indebtedness outstanding. To the extent that the aggregate principal amount of Notes tendered pursuant to an Asset Sale Offer is less than the amount that the Company is required to purchase, the Company may use any remaining Excess Proceeds for
general corporate purposes in any manner not prohibited by this Indenture. If the aggregate principal amount of Notes surrendered by Holders thereof exceeds the amount that the Company is required to purchase, the Trustee shall select the Notes to
be purchased on a pro rata basis (with such adjustments as may be deemed appropriate by the Trustee so that only Notes in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof, shall be purchased). Upon completion
of such offer to purchase, the amount of Excess Proceeds shall be reset at zero. 
  

 - 46 - 

 The Company shall not, and shall not permit any Restricted Subsidiary to, enter into or suffer to exist any
agreement (other than any agreement governing the Credit Facility) that would place any restriction of any kind (other than pursuant to law or regulation) on the ability of the Company to make an Asset Sale Offer. 
  
 Section 4.11 TRANSACTIONS WITH AFFILIATES.

  
 The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding,
loan, advance or guarantee with, or for the benefit of, any Affiliate (each of the foregoing, an “Affiliate Transaction”), unless (a) such Affiliate Transaction is on terms that are no less favorable to the Company or the relevant
Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person or, if there is no such comparable transaction, on terms that are fair and reasonable to
the Company or such Restricted Subsidiary, and (b) the Company delivers to the Trustee (i) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $10,000,000, a resolution
of the Board of Directors set forth in an Officers’ Certificate certifying that such Affiliate Transaction complies with clause (a) above and that such Affiliate Transaction has been approved by a majority of the disinterested members of the
Board of Directors and (ii) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $20,000,000, an opinion as to the fairness to the Company or the relevant Subsidiary of
such Affiliate Transaction from a financial point of view issued by an accounting, appraisal or investment banking firm that is, in the judgment of the Board of Directors, qualified to render such opinion and is independent with respect to the
Company, provided that such opinion will not be required with respect to any Affiliate Transaction or series of related Affiliate Transactions involving either (i) shipyard contracts that are awarded following a competitive bidding process and
approved by a majority of the disinterested members of the Board of Directors or (ii) an Affiliate in which an unrelated third person owns Voting Stock in excess of that owned by the Company or any of its Restricted Subsidiaries; provided,
however, that the following shall be deemed not to be Affiliate Transactions: (A) any employment agreement or other employee compensation plan or arrangement entered into by the Company or any of its Restricted Subsidiaries in the ordinary
course of business of the Company or such Restricted Subsidiary; (B) transactions between or among the Company and its Restricted Subsidiaries; (C) Permitted Investments and Restricted Payments that are permitted by the provisions of Section 4.07 of
this Indenture; (D) loans or advances to officers, directors and employees of the Company or any of its Restricted Subsidiaries made in the ordinary course of business and consistent with past practices of the Company and its Restricted Subsidiaries
in an aggregate amount not to exceed $500,000 outstanding at any one time; (E) indemnities of officers, directors and employees of the Company or any of its Restricted Subsidiaries permitted by bylaw or statutory provisions; (F) maintenance in the
ordinary course of business of customary benefit programs or arrangements for officers, directors and employees of the Company or any Restricted Subsidiary, including without limitation vacation plans, health and life insurance plans, deferred
compensation plans, retirement or savings plans and similar plans; (G) registration rights or similar agreements with officers, directors or significant shareholders of the Company or any Restricted Subsidiary; (H) issuance of Equity Interests
(other than Disqualified 
  

 - 47 - 

 Stock) by the Company; and (I) the payment of reasonable and customary regular fees to directors of the Company or any of its
Restricted Subsidiaries who are not employees of the Company or any Affiliate. 
  
 Section 4.12 LIENS. 
  
 The Company shall
not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur or assume any Lien on any property or asset owned on the Issue Date or thereafter acquired, or any income or profits therefrom, except Permitted
Liens, to secure (a) any Indebtedness of the Company, unless prior to, or contemporaneously therewith, the Notes are equally and ratably secured, until such time as such Indebtedness is no longer secured by a Lien (other than Permitted Liens) or (b)
any Indebtedness of any Guarantor, unless prior to, or contemporaneously therewith, its Subsidiary Guarantee is equally and ratably secured, until such time as such Indebtedness is no longer secured by a Lien (other than Permitted Liens);
provided, however, that if such Indebtedness is expressly subordinated to the Notes or the Subsidiary Guarantees, the Lien securing such Indebtedness shall be subordinated and junior to the Lien securing the Notes or the Subsidiary
Guarantees, as the case may be, with the same relative priority as such Indebtedness has with respect to the Notes or the Subsidiary Guarantees. 
  
 Section 4.13 ADDITIONAL SUBSIDIARY GUARANTEES. 
  
 If the Company or any of its Restricted Subsidiaries shall, after the Issue Date, acquire or create another Significant Subsidiary or
if any other Restricted Subsidiary shall become such, then such Significant Subsidiary shall become a Guarantor by executing a supplemental indenture in substantially the form of Exhibit E hereto and delivering it to the Trustee, together with a
notation of Subsidiary Guarantee, an Opinion of Counsel and an Officers’ Certificate, in accordance with the terms of Section 10.02 of this Indenture; provided, however, that this requirement shall not apply to a Significant Subsidiary
that is also a Foreign Subsidiary. If, after the Issue Date, any Restricted Subsidiary of the Company (including a Foreign Subsidiary) that is not already a Guarantor shall guarantee any other Indebtedness of the Company or any Indebtedness of a
Domestic Subsidiary, then that Subsidiary shall become a Guarantor by executing a supplemental indenture in substantially the form of Exhibit E hereto and delivering it to the Trustee, together with a notation of Subsidiary Guarantee, an Opinion of
Counsel and an Officers’ Certificate, in accordance with the terms of such Section10.02, within ten Business Days of the date on which it guaranteed such Indebtedness. Notwithstanding the preceding, any Subsidiary Guarantee of a Restricted
Subsidiary (other than a Significant Subsidiary) shall be unconditionally released, as provided in Section 10.05 hereof, upon the release or discharge of its guarantee of all other Indebtedness of the Company or any of its Domestic Subsidiaries,
except a release or discharge by, or as a result of payment under, such guarantee. 
  
 Section 4.14 CORPORATE EXISTENCE. 
  
 Subject to Article 5 hereof, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence, and, subject to Article 10 hereof, the corporate, partnership or other
existence of each of its Restricted Subsidiaries, in accordance with the 
  

 - 48 - 

 respective organizational documents (as the same may be amended from time to time) of the Company or any such Restricted
Subsidiary; provided, however, that the Company shall not be required to preserve the existence of any of its Restricted Subsidiaries, if the Company shall determine that the preservation thereof is no longer desirable in the conduct of the
business of the Company and its Restricted Subsidiaries, taken as a whole. 
  
 Section
4.15 OFFER TO PURCHASE UPON CHANGE OF CONTROL. 
  
 (a) Upon the occurrence of a Change of Control, the Company shall make an offer (a “Change of Control Offer”) to purchase all or any portion (equal
to minimum amounts of $2,000 and integral multiples of $1,000 in excess thereof) of each Holder’s Notes, at a purchase price in cash equal to 101% of the aggregate principal amount thereof, plus accrued and unpaid interest, if any, thereon to
the date of purchase (the “Change of Control Payment”), subject to the right of Noteholders of record on the relevant record date to receive interest due on an interest payment date that is on or prior to such date of purchase.
Within 30 days following a Change of Control, the Company shall give notice to each Holder and the Trustee stating: (1) that the Change of Control Offer is being made pursuant to this Section 4.15 and that all Notes validly tendered and not
withdrawn will be accepted for payment; (2) the purchase price and the purchase date, which shall be no earlier than 30 days but no later than 60 days from the date such notice is given (the “Change of Control Payment Date”); (3)
that any Note not tendered will continue to accrue interest; (4) that, unless the Company defaults in the payment of the Change of Control Payment, all Notes accepted for payment pursuant to the Change of Control Offer shall cease to accrue interest
after the Change of Control Payment Date; (5) that Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender the Notes, properly endorsed for transfer, together with the form entitled
“Option of Holder to Elect Purchase” on the reverse of the Notes completed and such customary documents as the Company may reasonably request, to the Paying Agent at the address specified in the notice prior to the close of business on the
third Business Day preceding the Change of Control Payment Date; (6) that Holders will be entitled to withdraw their election if the Paying Agent receives, not later than the close of business on the second Business Day preceding the Change of
Control Payment Date, a telegram, facsimile transmission or letter setting forth the name of the Holder, the principal amount of Notes delivered for purchase, and a statement that such Holder is withdrawing his election to have the Notes purchased;
and (7) that Holders whose Notes are being purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to a minimum of $2,000 in principal
amount. If any of the Notes subject to a Change of Control Offer is in the form of a Global Note, then the Company shall modify such notice to the extent necessary to accord with the procedures of the Depository applicable to repurchases. Further,
the Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the purchase of Notes as a result
of a Change of Control. To the extent that the provisions of any securities laws or regulations conflict with the provisions relating to the Change of Control Offer, the Company shall comply with the applicable securities laws and regulations and
shall not be deemed to have breached its obligations described in this Section 4.15 by virtue thereof. 
  

 - 49 - 

 (b) At or before 11:00 a.m., New York time, on the Change of Control Payment Date, the Company shall, to the extent
lawful, (a) accept for payment all Notes or portions thereof properly tendered pursuant to the Change of Control Offer, (b) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions thereof so
tendered and (c) deliver or cause to be delivered to the Trustee the Notes so accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions thereof being purchased by the Company. The Paying Agent
shall promptly deliver to each Holder of Notes so tendered the Change of Control Payment for such Notes, and the Trustee shall promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal
amount to any unpurchased portion of the Notes surrendered, if any; provided, however, that each such new Note will be in a minimum principal amount of $2,000. The Company shall publicly announce the results of the Change of Control Offer on
or as soon as practicable after the Change of Control Payment Date. 
  
 (c)
The Change of Control provisions described above shall be applicable whether or nor any other provisions of this Indenture are applicable. 
  
 (d) The Company shall not be required to make a Change of Control Offer following a Change of Control if a third party makes the Change of Control Offer in the
manner, at the time and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer made by the Company and purchases all Notes validly tendered and not withdrawn under such Change of Control
Offer. 
  
 Section 4.16 ISSUANCES AND SALES
OF CAPITAL STOCK OF RESTRICTED SUBSIDIARIES. 
  
 The Company (i) shall not, and shall not permit any Restricted Subsidiary of the Company to, transfer, convey, sell or otherwise dispose of any Capital Stock of any
Restricted Subsidiary of the Company to any Person (other than the Company or a Wholly Owned Restricted Subsidiary of the Company), unless (a) such transfer, conveyance, sale or other disposition is of all the Capital Stock of such Restricted
Subsidiary and (b) the Net Proceeds from such transfer, conveyance, sale or other disposition are applied in accordance with Section 4.10 hereof, and (ii) shall not permit any Restricted Subsidiary of the Company to issue any of its Equity Interests
to any Person other than to the Company or a Wholly Owned Restricted Subsidiary of the Company, except, in the case of both clauses (i) and (ii) above, with respect to (1) dispositions or issuances by a Wholly Owned Restricted Subsidiary of the
Company as contemplated in clauses (a) and (b) of the definition of “Wholly Owned Restricted Subsidiary” or (2) other dispositions or issuances of Capital Stock of a Restricted Subsidiary of the Company, provided that, after giving pro
forma effect thereto, the Investment of the Company and its Restricted Subsidiaries in all Restricted Subsidiaries that are not Wholly Owned Restricted Subsidiaries of the Company, determined on a consolidated basis in accordance with GAAP, does not
exceed 25% of Consolidated Net Tangible Assets of the Company. For purposes of this Section 4.16, the creation or perfection of a Lien on any Capital Stock of a Restricted Subsidiary of the Company to secure any Indebtedness of the Company or any of
its Restricted Subsidiaries shall not be deemed to be a disposition of such Capital Stock; provided, however, any sale by the secured party of such Capital Stock following foreclosure of its Lien shall be subject to this Section 4.16.

  

 - 50 - 

 Section 4.17 SALE-AND-LEASEBACK TRANSACTIONS. 
  
 The Company shall not, and shall not permit any of its Restricted Subsidiaries to,
enter into any sale-and-leaseback transaction; provided, however, that the Company or any Restricted Subsidiary, as applicable, may enter into a sale-and-leaseback transaction if (i) the Company or such Restricted Subsidiary could have (a)
incurred Indebtedness in an amount equal to the Attributable Indebtedness relating to such sale-and-leaseback transaction pursuant to the Consolidated Interest Coverage Ratio test set forth in the first paragraph of Section 4.09 hereof, provided,
however, that this clause (2) shall no longer be effective if the Terminated Covenants shall have terminated in accordance with Section 4.19 hereof, and (b) incurred a Lien to secure such Indebtedness pursuant to Section 4.12 hereof, (ii) the
gross cash proceeds of such sale-and-leaseback transaction are at least equal to the fair market value (as determined in accordance with the definition of such term, the results of which determination shall be set forth in an Officers’
Certificate delivered to the Trustee) of the properties or assets that are the subject of such sale-and-leaseback transaction and (iii) the transfer of such properties or assets in such sale-and-leaseback transaction is permitted by, and the Company
applies the proceeds of such transaction in compliance with, Section 4.10 hereof. 
  
 Section 4.18 NO INDUCEMENTS. 
  
 The Company shall not, and the Company shall not permit any of its Subsidiaries, either directly or indirectly, to pay (or cause to be paid) any consideration, whether by way of interest, fee or otherwise, to any Holder for or as an
inducement to any consent, waiver, amendment or supplement of any terms or provisions of this Indenture or the Notes, unless such consideration is offered to be paid (or agreed to be paid) to all Holders which so consent, waive or agree to amend or
supplement in the time frame set forth on solicitation documents relating to such consent, waiver, agreement or supplement. 
  
 Section 4.19 COVENANT TERMINATION. 
  
 (a) Once the Notes have achieved an Investment Grade Rating and no Default has occurred and is continuing under this Indenture, the Company and its Restricted
Subsidiaries shall no longer be subject to Sections 3.09, 4.07, 4.08, 4.09, 4.10, 4.11, 4.15, 4.16 and 4.21 of this Indenture (collectively, the “Terminated Covenants”) and any provision of the Notes inconsistent with the
elimination of the Terminated Covenants; provided, however, the Company and its Restricted Subsidiaries shall remain subject to Sections 4.01-4.06, 4.12, 4.13, 4.14, 4.17 (except to the extent set forth therein), 4.18, 4.20 and 5.01 (except
to the extent set forth therein) of this Indenture. The Company shall deliver promptly to the Trustee an Officers’ Certificate notifying it of such occurrence. 
  
 (b) After termination of the Terminated Covenants, for purposes of complying with Section 4.12, the Liens described in clauses (a) and
(m) of the definition of “Permitted Liens” shall be Permitted Liens only to the extent those Liens secure Indebtedness not exceeding, at the time of determination, 10% of the Consolidated Net Tangible Assets of the Company. Once effective,
this 10% limitation on Permitted Liens shall continue to apply during any later period in which the Notes do not have an Investment Grade Rating.

 Section 4.20 ENFORCEABILITY OF JUDGMENTS; INDEMNIFICATION
FOR FOREIGN CURRENCY JUDGMENTS. 
  
 The obligations of the Company to any Holder or the Trustee shall, notwithstanding any judgment in a currency (the “Judgment Currency”) other than
United States dollars (the “Agreement Currency”), be discharged only to the extent that on the day following receipt by such Holder or the Trustee, as the case may be, of any amount in the Judgment Currency, such Holder or the
Trustee may in accordance with normal banking procedures purchase the Agreement Currency with the Judgment Currency. If the amount of the Agreement Currency so purchased is less than the amount originally to be paid to such Holder or the Trustee, as
the case may be, in the Agreement Currency, the Company agrees, as a separate obligation and notwithstanding such judgment, to pay to such Holder or the Trustee, as the case may be, the difference, and if the amount of the Agreement Currency so
purchased exceeds the amount originally to be paid to such Holder or the Trustee, as the case may be, such Holder or the Trustee, as the case may be, shall pay to or for the account of the Company such excess, provided that such Holder or the
Trustee, as the case may be, shall not have any obligation to pay any such excess as long as a Default has occurred and is continuing, in which case such excess may be applied by such Holder or the Trustee, as the case may be, to such obligations.

  
 Section 4.21 CONDUCT OF BUSINESS.

  
 The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, engage in the conduct of any business other than the marine transportation and logistics business and such other businesses as are complementary or related thereto as determined in good faith by the Board of Directors.

transfer, lease, conveyance or other disposition, the provisions of this Indenture referring to the “Company” shall refer instead to the successor corporation and not to the Company), and may exercise every right and power of the Company
under this Indenture with the same effect as if such successor corporation had been named as the Company herein; provided, however, that the predecessor Company shall not be relieved from its obligations under this Indenture or the Notes in

 ARTICLE 6 
 DEFAULTS AND REMEDIES 
  
 Section 6.01 EVENTS OF DEFAULT. 
  
 An “Event of Default” occurs if: 
  
 (a) the Company defaults in the payment when due of interest (including any Additional Interest) on the Notes, and such default continues for a period of 30 days;

  
 (b) the Company defaults in the payment when due of principal of or
premium, if any, on the Notes; 
  
 (c) the Company fails to comply with any
of the then applicable provisions of Section 3.09, 4.10, 4.15 or 5.01 hereof; 
  

 - 53 - 

 (d) the Company fails to observe or perform any other then applicable covenant or other agreement in this Indenture
or the Notes for 60 days after it receives written notice from the Trustee or the Holders of at least 25% in principal amount of the Notes then outstanding of such failure; 
  
 (e) a default occurs under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or
evidenced any Indebtedness for money borrowed by the Company or any of its Restricted Subsidiaries (or the payment of which is guaranteed by the Company or any of its Restricted Subsidiaries), whether such Indebtedness or guarantee now exists, or is
created after the Issue Date, which default (i) is caused by a failure to pay principal of or premium or interest on such Indebtedness prior to the expiration of any grace period provided in such Indebtedness, including any extension thereof (a
“Payment Default”) or (ii) results in the acceleration of such Indebtedness prior to its express maturity and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such
Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates at least $10,000,000; and provided, further, that if such default is cured or waived or any such acceleration rescinded, or
such Indebtedness is repaid, within a period of 10 days from the continuation of such default beyond the applicable grace period or the occurrence of such acceleration, as the case may be, an Event of Default and any consequential acceleration of
the Notes shall be automatically rescinded, so long as such rescission does not conflict with any judgment or decree; 
  
 (f) a final judgment or final judgments for the payment of money are entered by a court or courts of competent jurisdiction against the Company or any of its
Restricted Subsidiaries and such judgment or judgments are not paid or discharged for a period (during which execution shall not be effectively stayed) of 60 days, provided that the aggregate of all such undischarged judgments exceeds $10,000,000;

  
 (g) the failure of any Guarantor to perform any covenant set forth in
its Subsidiary Guarantee or the repudiation by any Guarantor of its obligations under its Subsidiary Guarantee or the unenforceability of any Subsidiary Guarantee for any reason other than as provided in this Indenture; 
  
 (h) the Company or any Significant Subsidiary pursuant to or within the meaning of
Bankruptcy Law: 
  
 (i) commences a voluntary case,

  
 (ii) consents to the entry of an order for relief
against it in an involuntary case, 
  
 (iii) consents to
the appointment of a Custodian of it or for all or substantially all of its property, 
  
 (iv) makes a general assignment for the benefit of its creditors, or 
  
 (v) generally is not paying its debts as they become due; or

 (i) is for relief against the Company or any Significant Subsidiary in
an involuntary case; 
  
 (ii) appoints a Custodian of the
Company or any Significant Subsidiary or for all or substantially all of the property of the Company or any Significant Subsidiary; or 
  
 (iii) orders the liquidation of the Company or any Significant Subsidiary;

 Section 6.02 ACCELERATION. 
  
 If any Event of Default occurs and is continuing, the Trustee may, by notice to the
Company, or the Holders of at least 25% in principal amount of the then outstanding Notes may, by notice to the Company and the Trustee, and the Trustee shall, upon the request of such Holders, declare all the Notes to be due and payable
immediately. Upon any such declaration, the Notes shall become due and payable immediately. Notwithstanding the foregoing, if an Event of Default specified in clause (h) or (i) of Section 6.01 hereof occurs with respect to the Company, all
outstanding Notes shall be due and payable immediately without further action or notice. The Holders of a majority in principal amount of the then outstanding Notes by written notice to the Trustee may on behalf of all of the Holders rescind an
acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default (except nonpayment of principal, interest or premium, if any, that has become due solely because of such
acceleration) have been cured or waived. 
  
 If an Event of Default occurs
by reason of any willful action (or inaction) taken (or not taken) by or on behalf of the Company with the intention of avoiding payment of the premium that the Company would have had to pay if the Company then had elected to redeem the Notes
pursuant to Section 3.07 hereof, then, upon acceleration of the Notes, an equivalent premium shall also become and be immediately due and payable, to the extent permitted by law, anything in this Indenture or in the Notes to the contrary
notwithstanding. 
  
 Section 6.03 OTHER REMEDIES.

  
 If an Event of Default occurs and is continuing, the Trustee may
pursue any available remedy to collect the payment of principal of, or premium, if any, or interest on, the Notes or to enforce the performance of any provision of the Notes or this Indenture. 
  
 The Trustee may maintain a proceeding even if it does not possess any of the Notes or
does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of a Note 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 to the extent permitted by law. 
  

 - 55 - 

 Section 6.04 WAIVER OF PAST DEFAULTS. 
  
 Holders of a majority in principal amount of the then outstanding Notes by notice to
the Trustee may on behalf of the Holders of all of the Notes waive any existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of the principal of, or premium, if any, or
interest on, the Notes (including in connection with an offer to purchase). Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture;
but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon. 
  
 Section 6.05 CONTROL BY MAJORITY. 
  
 Holders of a majority in principal amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding for exercising 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 or that the Trustee determines may be unduly prejudicial to the rights of
other Holders of Notes or that may involve the Trustee in personal liability. 
  
 Section
6.06 LIMITATION ON SUITS. 
  
 A Holder of a Note may pursue a remedy with respect to this Indenture or the Notes only if: 
  
 (a) the Holder of a Note gives to the Trustee written notice of a continuing Event of Default; 
  
 (b) the Holders of at least 25% in principal amount of the then outstanding Notes make a written request to the Trustee to pursue the
remedy; 
  
 (c) such Holder of a Note or Holders of Notes offer and, if
requested, provide to the Trustee security or indemnity satisfactory to the Trustee against any loss, liability or expense; 
  
 (d) the Trustee does not comply with the request within 60 days after receipt of the request and the offer and, if requested, the provision of security or
indemnity; and 
  
 (e) during such 60 day period the Holders of a majority
in principal amount of the then outstanding Notes do not give the Trustee a direction inconsistent with the request. 
  
 A Holder of a Note may not use this Indenture to prejudice the rights of another Holder of a Note or to obtain a preference or priority over another Holder of a Note. 

 
 Section 6.07 RIGHTS OF HOLDERS OF
NOTES TO RECEIVE PAYMENT. 
  
 Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal of, and premium, if any, and interest on, the Note, on or after the 
  

 - 56 - 

 respective due dates expressed in the Note (including in connection with an offer to purchase), 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 such Holder. 
  
 Section 6.08 COLLECTION SUIT BY TRUSTEE. 
  
 If an Event of Default specified in Section 6.01(a) or (b) occurs and is continuing, the Trustee is authorized to recover judgment in
its own name and as trustee of an express trust against the Company for the whole amount of principal, premium, if any, and interest remaining unpaid on the Notes and interest on overdue principal and premium, if any, and, to the extent lawful,
interest and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. 
  
 Section 6.09 TRUSTEE MAY FILE PROOFS
OF CLAIM. 
  
 The Trustee is authorized
to 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 (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its
agents and counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Company (or any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute

proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such
proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. 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 Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

 Section 7.05 NOTICE OF DEFAULTS. 
  
 If a Default or Event of Default occurs and is continuing and if it is known to the
Trustee, the Trustee shall mail to Holders of Notes a notice of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in payment of principal of, or premium, if any, or interest on, any
Note, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders of the Notes. 
  
 Section 7.06 REPORTS BY TRUSTEE TO
HOLDERS OF THE NOTES. 
  
 Within 60 days after each May 15 beginning with the May 15 following the date of this Indenture, and for so long as Notes remain outstanding, the Trustee shall mail to the Holders of the Notes a brief report dated as of such
reporting date that complies with TIA §313(a) (but if no event described in TIA §313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted). The Trustee also shall comply with
TIA §313(b)(2) and §313(b)(1). The Trustee shall also transmit by mail all reports as required by TIA §313(c). 
  
 Commencing at the time this Indenture is qualified under the TIA, a copy of each report at the time of its mailing to the Holders of Notes shall be mailed to the

 Section 7.07 COMPENSATION AND INDEMNITY.

  
 The Company shall pay to the Trustee from time to time reasonable

for all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses shall include the reasonable compensation, disbursements and expenses of the Trustee’s agents and
counsel. 
  
 The Company and the Guarantors shall indemnify the Trustee
against any and all losses, liabilities or expenses incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture, including the costs and expenses of enforcing this Indenture against the
Company (including this Section 7.07) and defending itself against any claim (whether asserted by the Company, any Guarantor or any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or
duties hereunder, except to the extent any such loss, liability or expense may be attributable to its negligence, bad faith or willful misconduct. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by
the Trustee to so notify the Company shall not relieve the Company or the Guarantors of their obligations hereunder. The Company shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have separate counsel and the
Company shall pay the reasonable fees and expenses of one such counsel. The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld.

 The obligations of the Company and the Guarantors under this Section 7.07 shall survive the satisfaction and
discharge of this Indenture. 
  
 To secure the Company’s payment
obligations in this Section 7.07, the Trustee shall have a Lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal of, or premium, if any, or interest on, particular Notes. Such
Lien shall survive the satisfaction and discharge of this Indenture. 
  
 When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(h) or (i) hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel)
are intended to constitute expenses of administration under any applicable bankruptcy law. 
  
 The Trustee shall comply with the provisions of TIA §313(b)(2) to the extent applicable.

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. 
  
 The Trustee may resign in
writing at any time and be discharged from the trust hereby created by so notifying the Company. The Holders of Notes of a majority in principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Company
in writing. The Company may remove the Trustee if: 
  
 (a) the Trustee

 (b) the Trustee is adjudged a
bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any applicable bankruptcy law;

Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Company. 
  
 If a successor Trustee does not take office within 60 days after the retiring Trustee
resigns or is removed, the retiring Trustee, the Company, or the Holders of Notes of at least 10% in principal amount of the then outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee.

  
 If the Trustee, after written request by any Holder of a Note who has
been a Holder of a Note for at least six months, fails to comply with Section 7.10 hereof, such Holder of a Note may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 

 

 - 62 - 

 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 Holders of the Notes. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, provided that all sums owing to the Trustee hereunder have been paid and subject to the Lien provided
for in Section 7.07 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Company’s obligations under Section 7.07 hereof shall continue for the benefit of the retiring Trustee. 
  
 Section 7.09 SUCCESSOR TRUSTEE BY
MERGER, ETC. 
  
 If the Trustee
consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the successor corporation without any further act shall be the successor Trustee. As soon as practicable, the
successor Trustee shall mail a notice of its succession to the Company and the Holders of the Notes. Any such successor must nevertheless be eligible and qualified under the provisions of Section 7.10 hereof. 
  
 Section 7.10 ELIGIBILITY; DISQUALIFICATION.

a combined capital and surplus of at least $100,000,000 as set forth in its most recent published annual report of condition. 
  
 This Indenture shall always have a Trustee who satisfies the requirements of TIA §310(a)(1), (2) and (5). The Trustee is subject to TIA §310(b);
provided, however, that there shall be excluded from the operation of TIA §310(b)(1) any indenture or indentures under which other securities, or certificates of interest or participation in other securities, of the Company are
outstanding, if the requirements for such exclusion set forth in TIA §310(b)(1) are met. 
  
 Section 7.11 PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY. 
  
 The Trustee is subject to 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 therein.

this Section 8.02, the Company shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have discharged its obligations with respect to all outstanding Notes, and each Guarantor shall be deemed to have
discharged its obligations with respect to its Subsidiary Guarantee, on the date the conditions set forth in Section 8.04 below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the
Company shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes, and each Guarantor shall be deemed to have paid and discharged its Subsidiary Guarantee (which in each case shall thereafter be deemed
to be “outstanding” only for the purposes of Section 8.06 hereof and the other Sections of this Indenture referred to in (a) and (b) below) and to have satisfied all its other obligations under such Notes or Subsidiary Guarantee and this
Indenture (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following provisions which shall survive until otherwise terminated or discharged hereunder: (a) the
rights of Holders of outstanding Notes to receive solely from the trust fund described in Section 8.04 hereof, and as more fully set forth in such Section, payments in respect of the principal of, and premium, if any, and interest on, such Notes
when such payments are due, (b) the Company’s obligations with respect to such Notes under Sections 2.03, 2.04, 2.07, 2.10 and 4.02 hereof, (c) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Company’s

For this 
  

 - 64 - 

 purpose, Covenant Defeasance means that, with respect to the outstanding Notes, the Company and any Guarantor 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 under Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and
such Notes shall be unaffected thereby. In addition, upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03 hereof, subject to the satisfaction of the conditions set forth in Section 8.04 hereof,

occurred; 
  
 (c) in the case of an election under Section 8.03 hereof, the
Company shall have delivered to the Trustee an Opinion of Counsel in the United States reasonably acceptable to the Trustee confirming that the Holders of the outstanding Notes will not recognize income, gain or loss for U.S. federal income tax

insolvency, reorganization or similar laws affecting creditors’ rights generally; 
  
 (g) 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

 Subject to applicable escheat and abandoned property laws, any money or U.S.
Government Securities deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, or premium, if any, or interest on, any Note and remaining unclaimed for two years after such principal,
premium, if any, or interest has become due and payable shall be paid to the Company or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to
the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money or U.S. Government Securities, and all liability of the Company as trustee thereof, shall thereupon cease; provided,
however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in Investor’s Business Daily and The Wall Street Journal (national
edition), notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining will be repaid to
the Company. 
  
 Nothing contained in this Section 8.07 shall be deemed to
affect any obligation of the Trustee or any Paying Agent to search for lost Holders pursuant to Rule 17Ad 17 under the Exchange Act. 
  
 Section 8.08 REINSTATEMENT. 
  
 If the Trustee or a Paying Agent is unable to apply any dollars or U.S. Government Securities in accordance with Section 8.05 or 8.06 hereof, by reason of any order
or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s and the Guarantors’ obligations under this Indenture, the Notes and the Subsidiary 
  

 - 68 - 

 Guarantees shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.02, 8.03 or 8.05 hereof until
such time as the Trustee or such Paying Agent is permitted to apply all such money in accordance with Section 8.05 or 8.06 hereof, as the case may be; provided, however, that, if the Company or any Guarantor makes any payment of principal of,
or premium, if any, or interest on, any Note following the reinstatement of its obligations, then it shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or U.S. Government Securities held by the
Trustee or such Paying Agent. 
  
 ARTICLE 9 
 AMENDMENT, SUPPLEMENT AND WAIVER 
  
 Section 9.01 WITHOUT CONSENT OF HOLDERS OF NOTES. 
  
 Notwithstanding Section 9.02 of this Indenture, the Company, the Guarantors and the
Trustee may amend or supplement this Indenture or the Notes without the consent of any Holder of a Note: 
  
 (a) to cure any ambiguity, defect or inconsistency; 
  
 (b) to provide for uncertificated Notes in addition to or in place of certificated Notes; 
  
 (c) to provide for the assumption of the Company’s obligations to the Holders of the Notes pursuant to Article 5 hereof;

  
 (d) to secure the Notes pursuant to the requirements of Section 4.12 or
otherwise; 
  
 (e) to make any change that would provide any additional
rights or benefits to the Holders of the Notes or that does not adversely affect the legal rights hereunder of any Holder of the Note, provided that any change to conform this Indenture to the Company’s final offering circular relating to the
Series A Notes shall not be deemed to adversely affect such legal rights; 
  
 (f) to add or to release any Guarantor, in each case as provided in Article 10 hereof; or 
  
 (g) to comply with requirements of the SEC in order to effect or maintain the qualification of this Indenture under the TIA. 
  
 Upon the request of the Company accompanied by a Board Resolution authorizing the
execution of any such amended or supplemental indenture, and upon receipt by the Trustee of the documents described in Section 9.06 hereof, the Trustee shall join with the Company and the Guarantors in the execution of any amended or supplemental
indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to enter into such amended or supplemental
Indenture that affects its own rights, duties or immunities under this Indenture or otherwise. 
  

 - 69 - 

 Section 9.02 WITH CONSENT OF HOLDERS OF
NOTES. 
  
 Except as provided below in this Section
9.02, the Company, the Guarantors and the Trustee may amend or supplement this Indenture and the Notes may be amended or supplemented with the consent of the Holders of at least a majority in principal amount of the Notes then outstanding
(including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for the Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of Default or compliance with any
provision of this Indenture or the Notes may be waived with the consent of the Holders of a majority in principal amount of the then outstanding Notes (including, without limitation, consents obtained in connection with a tender offer or exchange
offer for the Notes). 
  
 Upon the request of the Company accompanied by a
Board Resolution authorizing the execution of any such amended or supplemental indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the
Trustee of the documents described in Section 9.06 hereof, the Trustee shall join with the Company and the Guarantors in the execution of such amended or supplemental indenture unless such amended or supplemental indenture affects the Trustee’s
own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such amended or supplemental indenture. 
  
 It shall not be necessary for the consent of the Holders of Notes under this Section
9.02 to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof. 
  

After an amendment, supplement or waiver under this Section becomes effective, the Company shall mail to the Holders of Notes affected thereby a notice briefly
describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amended or supplemental Indenture or waiver. Subject to
Sections 6.04 and 6.07 hereof, the Holders of a majority in principal amount of the Notes then outstanding may waive compliance in a particular instance by the Company with any provision of this Indenture or the Notes. However, without the consent
of each Holder affected, an amendment, supplement or waiver may not (with respect to any Notes held by a non-consenting Holder): 
  
 (a) reduce the principal amount of Notes whose Holders must consent to an amendment, supplement or waiver; 
  
 (b) reduce the principal of or change the fixed maturity of any Note or alter any of
the provisions with respect to the redemption or purchase of the Notes by the Company (except other than the provisions of Sections 3.09, 4.10 and 4.15 hereof); 
  

(c) reduce the rate of or change the time for payment of interest on any Note; 
  
 (d) waive a Default or Event of Default in the payment of principal of, or premium, if any, or interest on, the Notes (except a
rescission of acceleration of the Notes by the Holders of at least a majority in principal amount of the Notes and a waiver of the payment default that resulted from such acceleration); 
  

 - 70 - 

 (e) make any Note payable in money other than that stated in the Notes; 
  
 (f) make any change in the provisions of this Indenture relating to waivers of past
Defaults or Events of Default or the rights of Holders of Notes to receive payments of principal of, or premium, if any, or interest on, the Notes (except as permitted in clause (g) below); 
  
 (g) waive a redemption or repurchase payment with respect to any Note (other than a
payment required by Sections 4.10 and 4.15 hereof); 
  
 (h) make any change
in the ranking of the Notes relative to other Indebtedness of the Company or in any Subsidiary Guarantee relative to other Indebtedness of the Guarantors, in either case in a manner adverse to the Holders of Notes; or 
  
 (i) make any change in the foregoing amendment, supplement and waiver provisions.

  
 Section 9.03 COMPLIANCE WITH TRUST
INDENTURE ACT. 
  
 Every amendment or
supplement to this Indenture or the Notes shall be set forth in an amended or supplemental Indenture that complies with the TIA as then in effect. 
  
 Section 9.04 REVOCATION AND EFFECT OF CONSENTS. 
  
 Until an amendment, supplement or waiver becomes effective, a consent to it by a
Holder of a Note is a continuing consent by the Holder of a Note and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note.
However, any such Holder of a Note or subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the waiver, supplement or amendment becomes effective. An amendment,
supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder. 
  
 Section 9.05 NOTATION ON OR EXCHANGE OF NOTES. 
  
 The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The
Company in exchange for all Notes may issue and the Trustee shall authenticate new Notes that reflect the amendment, supplement or waiver. 
  
 Failure to make the appropriate notation or issue a new Note shall not affect the validity and effect of such amendment, supplement or waiver. 
  
 Section 9.06 TRUSTEE TO SIGN AMENDMENTS,
ETC. 
  
 The Trustee shall sign any amended or
supplemental indenture authorized pursuant to this Article 9 if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. The Company may not sign an amendment or supplemental indenture

  

 - 71 - 

 until the Board of Directors approves it. In executing any amended or supplemental indenture, the Trustee shall be entitled to
receive and (subject to Section 7.01) shall be fully protected in relying upon, an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this
Indenture. 
  
 ARTICLE 10 
 GUARANTEES OF NOTES 
  
 Section 10.01 SUBSIDIARY GUARANTEES. 
  
 Subject to Section 10.06 hereof, the Guarantors hereby, jointly and severally, unconditionally guarantee to each Holder of a Note authenticated and delivered by the
Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes held thereby and the Obligations of the Company hereunder and thereunder, that: (a) the principal of, and
premium, if any, and interest on, the Notes will be promptly paid in full when due, subject to any applicable grace period, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of, and premium, if any,
and interest (to the extent permitted by law) on, the Notes, and all other payment Obligations of the Company to the Holders or the Trustee hereunder or thereunder will be promptly paid in full and performed, all in accordance with the terms hereof
and thereof; and (b) in case of any extension of time of payment or renewal of any Notes or any of such other Obligations, the same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, subject
to any applicable grace period, whether at Stated Maturity, by acceleration, redemption or otherwise. Failing payment when so due of any amount so guaranteed or any performance so guaranteed for whatever reason the Guarantors will be jointly and
severally obligated to pay the same immediately. An Event of Default under this Indenture or the Notes shall constitute an event of default under the Subsidiary Guarantees, and shall entitle the Holders to accelerate the obligations of the
Guarantors hereunder in the same manner and to the same extent as the Obligations of the Company. The Guarantors hereby agree that their obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the
Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or any
other circumstance (other than complete performance) which might otherwise constitute a legal or equitable discharge or defense of a Guarantor. Each Guarantor further, to the extent permitted by law, 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 will
not be discharged except by complete performance of the Obligations contained in the Notes and this Indenture. If any Holder or the Trustee is required by any court or otherwise to return to the Company, the Guarantors, the Trustee or any Custodian
in relation to either the Company or the Guarantors, any amount paid by the Company or any Guarantor to the Trustee or such Holder, the Subsidiary Guarantees, to the extent theretofore discharged, shall be reinstated in full force and effect. Each
Guarantor agrees that it shall not be entitled to, and hereby waives, any right of subrogation in relation to the Holders in respect of any Obligations guaranteed hereby until payment in full of the Obligations guaranteed hereby. Each Guarantor
further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on 
  

 - 72 - 

 the other hand, (a) the maturity of the Obligations guaranteed hereby may be accelerated as provided in Article 6 hereof for the
purposes of its Subsidiary Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Obligations guaranteed thereby, and (b) in the event of any declaration of acceleration of such
Obligations as provided in Article 6 hereof, such Obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantor for the purpose of its Subsidiary Guarantee. 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. 
  
 Section 10.02 EXECUTION AND DELIVERY OF SUBSIDIARY GUARANTEE. 
  
 To evidence its Subsidiary Guarantee set forth in Section 10.01 hereof, each Guarantor
hereby agrees that a notation of such Subsidiary Guarantee in substantially the form of Exhibit D hereto may be endorsed by manual or facsimile signature by an Officer of such Guarantor on each Note authenticated and delivered by the Trustee and
that the supplemental indenture to this Indenture referred to in the next succeeding paragraph shall be executed on behalf of such Guarantor by an Officer of such Guarantor. 
  
 To the extent required by the provisions of Section 4.13 hereof, the Company shall cause each of its Restricted Subsidiaries to
execute a notation of Subsidiary Guarantee in substantially the form of Exhibit D hereto. Such notation of Subsidiary Guarantee shall be accompanied by a supplemental indenture in substantially the form of Exhibit E hereto, along with the Opinion of
Counsel and Officers’ Certificate required under Section 9.06 of this Indenture; provided, however, that any Subsidiary that has been properly designated as an Unrestricted Subsidiary in accordance with this Indenture need not execute a
notation of Subsidiary Guarantee or supplemental indenture for so long as it continues to constitute an Unrestricted Subsidiary. 
  
 The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Subsidiary Guarantees on behalf of the
Guarantors. Each Guarantor hereby agrees that its Subsidiary Guarantee shall remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Subsidiary Guarantee. 
  
 If an Officer whose signature is on the notation of Subsidiary Guarantee no longer
holds that office at the time the Trustee authenticates the Note on which a notation of Subsidiary Guarantee is endorsed, the Subsidiary Guarantee shall be valid nevertheless. 
  
 Section 10.03 GUARANTORS MAY CONSOLIDATE, ETC., ON
CERTAIN TERMS. 
  
 (a) Except as set
forth in Articles 4 and 5 hereof, nothing contained in this Indenture shall prohibit a merger between a Guarantor and another Guarantor or a merger between a Guarantor and the Company. 
  
 (b) No Guarantor shall consolidate with or merge with or into (whether or not such Guarantor is the surviving Person), another Person
(other than the Company or another Guarantor), whether or not affiliated with such Guarantor, unless: (i) subject to the provisions of Section 10.04 hereof, the Person formed by or surviving any such consolidation or merger (if other than such

  

 - 73 - 

 Guarantor) assumes all the obligations of such Guarantor under the Notes and this Indenture, pursuant to a supplemental indenture
in substantially the form of Exhibit E hereto, accompanied by a notation of its Subsidiary Guarantee as provided in such supplemental indenture; (ii) immediately after giving effect to such transaction, no Default or Event of Default exists; (iii)
such Guarantor, or any Person formed by or surviving any such consolidation or merger, would have a Consolidated Net Worth (immediately after giving effect to such transaction) equal to or greater than the Consolidated Net Worth of such Guarantor
immediately preceding the transaction; and (iv) the Company, immediately after giving pro forma effect to such transaction as if such transaction had occurred at the beginning of the applicable four-quarter period, would be permitted to incur
at least $1.00 of additional Indebtedness pursuant to the Consolidated Interest Coverage Ratio test set forth in the first paragraph of Section 4.09 hereof. 
  
 (c) In the case of any such consolidation or merger and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the
Trustee and substantially in the form of Exhibit E hereto, of the Subsidiary Guarantee and the due and punctual performance of all of the covenants of this Indenture to be performed by the Guarantor, such successor Person shall succeed to and be
substituted for the Guarantor with the same effect as if it had been named herein as a Guarantor. 
  
 Section 10.04 RELEASES FOLLOWING SALE OF GUARANTOR. 
  
 In the event of a sale or other disposition of all or substantially all of the properties or assets or all of the Capital Stock of any Guarantor, by way of merger,
consolidation or otherwise, then such Guarantor (in the event of a sale or other disposition, by way of such a merger, consolidation or otherwise, of all of the Capital Stock of such Guarantor) or the Person acquiring the properties or assets (in
the event of a sale or other disposition of all or substantially all of the properties or assets of such Guarantor) shall be released and relieved of any obligations under its Subsidiary Guarantee and this Indenture; provided, however, that
in the event such transaction constitutes an Asset Sale, the Net Proceeds from such sale or other disposition are treated in accordance with the provisions of Section 4.10 hereof. Upon delivery by the Company to the Trustee of an Officers’
Certificate to the effect of the foregoing, the Trustee shall execute any documents reasonably required in order to evidence the release of any Guarantor from its obligations under its Subsidiary Guarantee and this Indenture. Any Guarantor not
released from its obligations under its Subsidiary Guarantee shall remain liable for the full amount of principal of, and premium, if any, and interest on, the Notes and for the other Obligations of such Guarantor under this Indenture as provided in
this Article 10. 
  
 Section 10.05 RELEASES FOLLOWING
DESIGNATION AS AN UNRESTRICTED SUBSIDIARY. 
  
 In the event that (i) the Company designates a Guarantor to be an Unrestricted Subsidiary or (ii) the guarantee by a Guarantor (other than a Significant Subsidiary)
of all other Indebtedness of the Company or any of its Domestic Subsidiaries is released or discharged, except by, or as a result of payment under, such guarantee, then such Guarantor shall be released and relieved of any obligations under its
Subsidiary Guarantee and this Indenture; provided, however, that, in the case of clause (i), such designation is conducted in accordance with this Indenture. Upon delivery by the Company to the Trustee of an Officers’ Certificate to the
effect of the foregoing or following the occurrence of 
  

 - 74 - 

 either Legal Defeasance or the satisfaction and discharge of this Indenture pursuant to Section 8.05 hereof, the Trustee shall
execute any documents reasonably required in order to evidence the release of any Guarantor from its obligations under its Subsidiary Guarantee and this Indenture. 
  
 Section 10.06 LIMITATION ON GUARANTOR LIABILITY. 
  
 Each Guarantor and, by its acceptance of Notes, each Holder, hereby confirm 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 any applicable bankruptcy law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent
Transfer Act or any similar federal, state or foreign law to the extent applicable to any Subsidiary Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of such
Guarantor under its Subsidiary Guarantee and this Article 10 shall be limited to the maximum amount as will, after giving effect to such maximum amount and 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 this Article 10, result in the obligations
of such Guarantor under its Subsidiary Guarantee not constituting a fraudulent transfer or conveyance. 
  
 Section 10.07 “TRUSTEE” TO INCLUDE PAYING AGENT. 
  
 In case at any time any Paying Agent other than the Trustee shall have been appointed by the Company and be then acting hereunder, the
term “Trustee” as used in this Article 10 shall in each case (unless the context shall otherwise require) be construed as extending to and including such Paying Agent within its meaning as fully and for all intents and purposes as if such
Paying Agent were named in this Article 10 in place of the Trustee. 
  
 ARTICLE 11 
 MISCELLANEOUS

 (c) Further, prior to December
1, 2007, the Company may redeem on any one or more occasions Notes representing up to 35% of the aggregate principal amount of Notes originally issued under the Indenture (including any Notes originally issued after the Issue Date but excluding any
Series B Notes for purposes of calculating such amount) at a redemption price of 106.125% of the principal amount thereof, plus accrued and unpaid interest, if any, thereon to the redemption date, with the net cash proceeds of one or more Qualified
Equity Offerings, provided that (a) Notes representing at least 65% of the aggregate principal amount of Notes originally issued under the Indenture (including any Notes originally issued after the Issue Date but excluding any Series B Notes for
purposes of calculating such amount) remain outstanding immediately after the occurrence of each such redemption and (b) such redemption shall occur within 60 days of the date of the closing of each such Qualified Equity Offering. 
  
 6. MANDATORY REDEMPTION. 
  
 Except as set forth in paragraph 7 below, the Company shall not be required to make
mandatory redemption or sinking fund payments with respect to the Notes. 
  
 7. PUT OPTION OF HOLDER. 
  
 (a) If there is a Change of Control, the Company shall be required to make an offer (a “Change of Control Offer”) to purchase all or any portion (equal to
minimum amounts of $2,000 and integral multiples of $1,000 in excess thereof) of each Holder’s Notes, at a purchase price in cash equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest, if any, thereon to the
date of purchase (the “Change of Control Payment”). Within 30 days following any 
  

 A-6 

 Change of Control, the Company shall give notice to each Holder and the Trustee describing the transaction that constitutes the
Change of Control and setting forth the procedures governing the Change of Control Offer as required by the Indenture. 
  
 (b) If the Company or a Restricted Subsidiary consummates any Asset Sales, within 30 days of each date on which the aggregate amount of Excess Proceeds exceeds
$20,000,000, the Company shall commence an offer to all Holders of Notes (an “Asset Sale Offer”) pursuant to Section 3.09 of the Indenture to purchase the maximum principal amount of Notes that may be purchased out of the Excess Proceeds
at an offer price in cash in an amount equal to 100% of the principal amount thereof plus accrued and unpaid interest, if any, thereon to the date of purchase, in accordance with the procedures set forth in the Indenture; provided, however,
that, if the Company is required to apply such Excess Proceeds to purchase, or to offer to purchase, any Pari Passu Indebtedness, the Company shall only be required to offer to purchase the maximum principal amount of Notes that may be
purchased out of the amount of such Excess Proceeds multiplied by a fraction, the numerator of which is the aggregate principal amount of Notes outstanding and the denominator of which is the aggregate principal amount of Notes outstanding plus the
aggregate principal amount of Pari Passu Indebtedness outstanding. To the extent that the aggregate principal amount of Notes tendered pursuant to an Asset Sale Offer is less than the amount that the Company is required to purchase, the
Company may use any remaining Excess Proceeds for general corporate purposes in any manner not prohibited by the Indenture. If the aggregate principal amount of Notes surrendered by Holders thereof exceeds the amount that the Company is required to
purchase, the Trustee shall select the Notes to be purchased on a pro rata basis (with such adjustments as may be deemed appropriate by the Trustee so that only Notes in minimum denominations of $2,000 and integral multiples of $1,000 in
excess thereof, shall be purchased). Holders of Notes that are the subject of an offer to purchase will receive an Asset Sale Offer from the Company prior to any related purchase date and may elect to have such Notes purchased by completing the form
entitled “Option of Holder to Elect Purchase” on the reverse of the Notes. 
  
 8. NOTICE OF REDEMPTION. Notice of redemption will be mailed at least 30 days but not more than 60 days before the redemption date to each Holder whose Notes
are to be redeemed at its registered address. Notes in denominations larger than $2,000 may be redeemed in part but only in whole multiples of $1,000, unless all of the Notes held by a Holder are to be redeemed. On and after the redemption date
interest ceases to accrue on Notes or portions thereof called for redemption. 
  
 9. DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof. The
transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Company may
require a Holder to pay any transfer taxes or similar governmental charges. The Company need not exchange or register the transfer of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed
in part. Also, it need not exchange or register the transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed. 
  

 A-7 

 10. PERSONS DEEMED OWNERS. The registered Holder
of a Note may be treated as its owner for all purposes. 
  
 11.
AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain exceptions, the Indenture or the Notes may be amended or supplemented with the consent of the Holders of at least
a majority in principal amount of the then outstanding Notes, and any existing Default or Event of Default or compliance with any provision of the Indenture or the Notes may be waived with the consent of the Holders of at least a majority in
principal amount of the then outstanding Notes. Without the consent of any Holder of a Note, the Indenture or the Notes may be amended or supplemented to cure any ambiguity, defect or inconsistency, to provide for uncertificated Notes in addition to
or in place of certificated Notes, to provide for the assumption of the Company’s obligations to Holders of the Notes in case of a merger or consolidation, to secure the Notes, to make any change that would provide any additional rights or
benefits to the Holders of the Notes or that does not adversely affect the legal rights under the Indenture of any such Holder (provided that any change to conform the Indenture to the offering circular of the Company relating to the Series A Notes
will not be deemed to adversely affect such legal rights), to add any additional Guarantor or to release any Guarantor from its Subsidiary Guarantee, in each case as provided in the Indenture, or to comply with the requirements of the Commission in
order to effect or maintain the qualification of the Indenture under the Trust Indenture Act. 
  
 12. DEFAULTS AND REMEDIES. Events of Default include: (i) default for 30 days in the payment when due of interest, including Additional Interest, if any, on the
Notes; (ii) default in payment when due of the principal of or premium, if any, on the Notes; (iii) failure by the Company to comply with any of the then applicable provisions of Section 3.09, 4.10, 4.15 or 5.01 of the Indenture; (iv) failure by the
Company for 60 days after it receives written notice to observe or perform any other then applicable covenant or other agreement in the Indenture or the Notes; (v) default under any mortgage, indenture or instrument under which there may be issued
or by which there may be secured or evidenced any Indebtedness for money borrowed by the Company or any of its Restricted Subsidiaries (or the payment of which is guaranteed by the Company or any of its Restricted Subsidiaries), whether such
Indebtedness or guarantee now exists or is created after the Issue Date, which default (a) is caused by a failure to pay principal of or premium or interest on such Indebtedness prior to the expiration of any grace period provided in such
Indebtedness, including any extension thereof (a “Payment Default”) or (b) results in the acceleration of such Indebtedness prior to its express maturity and, in each case, the principal amount of any such Indebtedness, together with the
principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates at least $10,000,000, and provided, further, that if such default is cured or waived or any
such acceleration rescinded, or such Indebtedness is repaid within a period of 10 days from the continuation of such default beyond the applicable grace period or the occurrence of such acceleration, as the case may be, an Event of Default and any
consequential acceleration of the Notes shall be automatically rescinded, so long as said rescission does not conflict with any judgment or decree; (vi) failure by the Company or any of its Restricted Subsidiaries to pay final judgments aggregating
in excess of $10,000,000, which judgments are not paid, discharged or stayed for a period of 60 days; (vii) failure by any Guarantor to perform any covenant set forth in its Subsidiary Guarantee, or the repudiation by any Guarantor of its
obligations under its Subsidiary Guarantee or the unenforceability of any Subsidiary Guarantee for 
  

 A-8 

 any reason other than as provided in the Indenture; and (viii) certain events of bankruptcy or insolvency with respect to the
Company or any Significant Subsidiary. If any Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Notes may, by notice, declare all the Notes to be due and payable.
Notwithstanding the foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency with respect to the Company, all outstanding Notes will become due and payable without further action or notice. Holders may
not enforce the Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power. The
Trustee may withhold from Holders of the Notes notice of any continuing Default or Event of Default (except a Default or Event of Default relating to a payment obligation on the Notes) if it determines that withholding notice is in their interest.
The Holders of a majority in aggregate principal amount of the Notes then outstanding by notice to the Trustee may on behalf of the Holders of all of the Notes waive any existing Default or Event of Default and its consequences under the Indenture
except a continuing Default or Event of Default in the payment of the principal of, or premium, if any, or interest on, the Notes. The Company is required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and
the Company is required upon becoming aware of any Default or Event of Default, to deliver to the Trustee a statement specifying such Default or Event of Default. 
  
 13. DEFEASANCE. The Notes are subject to legal and covenant defeasance upon the terms and
conditions specified in Article 8 of the Indenture. 
  
 14.
TRUSTEE DEALINGS WITH COMPANY. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company or
its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not the Trustee. 
  
 15. NO RECOURSE AGAINST OTHERS. A director, officer, employee, incorporator,
member, partner or shareholder or other owner of Capital Stock of the Company or any Guarantor, as such, shall not have any liability for any obligations of the Company or any Guarantor under the Notes, the Subsidiary Guarantees or the Indenture or
for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Notes.

  
 16. AUTHENTICATION. This Note shall
not be valid until authenticated by the manual signature of an authorized signatory of the Trustee or an authenticating agent. 
  
 17. ABBREVIATIONS. Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in
common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act). 
  
 18. ADDITIONAL RIGHTS OF
HOLDERS. In addition to the rights provided to Holders of Notes under the Indenture, certain Holders shall have all the rights set forth in the Registration Rights Agreement dated as of even date with the Indenture,
among the Company, the Guarantors and the Initial Purchasers (the “Registration Rights Agreement”). 
  

 A-9 

 19. CUSIP NUMBERS. Pursuant to a recommendation promulgated by the Committee
on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy
of such numbers either as printed on the Notes or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon. 
  
 The Company will furnish to any Holder upon written request and without charge a copy of the Indenture or the Registration Rights
Agreement. Requests may be made to:

 Ladies and Gentlemen: 
  
 We are delivering this letter in connection with our purchase of 6.125% Senior Notes
due 2014 (the “Notes”) of Hornbeck Offshore Services, Inc. (the “Company”). We hereby confirm that: 
  
 (i) we are an “accredited investor” within the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act of 1933, as amended
(the “Securities Act”), or an entity in which all of the equity owners are accredited investors within the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act (an “Institutional Accredited Investor”); 

 
 (ii) any purchase of Notes by us will be for our own account or, if
we are buying for one or more institutional accounts for which we are acting as fiduciary or agent and we are not a bank (as defined in Section 3(a)(2) of the Securities Act) or a savings and loan association or other institution (as defined in
Section 3(a)(5)(A) of the Securities Act), each such account is an Institutional Accredited Investor; 
  
 (iii) we have such knowledge and experience in financial and business matters that we are capable of evaluating the merits and risks of purchasing
Notes and we, and any accounts for which we are acting, are able to bear the economic risks of its or their investment; 
  
 (iv) we are not acquiring Notes with a view to any distribution thereof in a transaction that would violate the Securities Act or the securities
laws of any State of the United States or any other applicable jurisdiction; provided, however, that the disposition of our property and the property of any accounts for which we are acting as fiduciary shall remain at all times within our control;
and 
  
 (v) we acknowledge that we have had access to such
financial and other information, and have been afforded the opportunity to ask such questions of representatives of the Company and receive answers thereto, as we deem necessary in connection with our decision to purchase Notes. 
  

 C-1 

 We understand that the Notes were offered in a transaction not involving any public offering within the meaning of
the Securities Act and that the Notes have not been registered under the Securities Act, and we agree, on our own behalf and on behalf of each account for which we acquire any Notes, that such Notes may be offered, resold, pledged or otherwise
transferred only (i) to a person whom we reasonably believe to be a qualified institutional buyer (as defined in Rule 144A under the Securities Act) in a transaction meeting the requirements of Rule 144A under the Securities Act, (ii) in a
transaction meeting the requirements of Rule 144 under the Securities Act, (iii) outside the United States in a transaction meeting the requirements of Rule 903 or 904 under the Securities Act, or in accordance with another exemption from the
registration requirements of the Securities Act (and based upon an opinion of counsel if the Company so requests), (iv) to the Company or any of its subsidiaries or (v) pursuant to an effective registration statement, and, in each case, in
accordance with any applicable securities laws of any State of the United States or any other applicable jurisdiction, and we will, and each subsequent holder of the Notes is required to, notify any subsequent purchaser from us or it of the resale
restrictions set forth in clause (i) above. We acknowledge that the Notes will bear legends substantially to the foregoing effect. We understand that the registrar will not be required to accept for registration of transfer any Notes, except upon
presentation of evidence satisfactory to the Company that the foregoing restrictions on transfer have been complied with. 
  
 We acknowledge that you and the Company will rely upon our confirmations, acknowledgments and agreements set forth herein, and we agree to notify you promptly in
writing if any of our representations or warranties herein ceases to be accurate and complete. 
  
 THIS LETTER SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

 NOTATION OF SUBSIDIARY GUARANTEE 
  
 Subject to Section 10.06 of the Indenture, each Guarantor has jointly and severally, unconditionally guaranteed to each Holder of a Note authenticated and delivered
by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of the Indenture, the Notes and the Obligations of the Company under the Notes or under the Indenture, that: (a) the principal of, and
premium, if any, and interest on, the Notes will be promptly paid in full when due, subject to any applicable grace period, whether at Stated Maturity, by acceleration, redemption or otherwise, and interest on overdue principal of, and premium, if
any, and interest (to the extent permitted by law) on, the Notes and all other payment Obligations of the Company to the Holders or the Trustee under the Indenture or under the Notes will be promptly paid in full and performed, all in accordance
with the terms thereof; and (b) in case of any extension of time of payment or renewal of any Notes or any of such other payment Obligations, the same will be promptly paid in full when due or performed in accordance with the terms of the extension
or renewal, subject to any applicable grace period, whether at Stated Maturity, by acceleration, redemption or otherwise. Failing payment when so due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors
will be jointly and severally obligated to pay the same immediately. An Event of Default under the Indenture or the Notes shall constitute an event of default under the Subsidiary Guarantees, and shall entitle the Holders to accelerate the
obligations of the Guarantors under the Indenture in the same manner and to the same extent as the Obligations of the Company. The Guarantors have agreed that their Obligations under the Indenture shall be unconditional, irrespective of the
validity, regularity or enforceability of the Notes or the Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder with respect to any provisions hereof or thereof, 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 further, to the extent permitted by law, has waived 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 will not be discharged except by complete performance of the Obligations contained in the Notes and the Indenture. If any Holder or the Trustee is required by any court or otherwise to return to the Company, the Guarantors, or any Note
Custodian, Trustee, liquidator or other similar official acting in relation to either the Company or the Guarantors, any amount paid by the Company or any Guarantor to the Trustee or such Holder, the Subsidiary Guarantees, to the extent theretofore
discharged, shall be reinstated in full force and effect. Each Guarantor has agreed that it shall not be entitled to, and hereby has waived, any right of subrogation in relation to the Holders in respect of any Obligations guaranteed under the
Indenture. Each Guarantor further has agreed that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (a) the maturity of the Obligations guaranteed under the Indenture may be accelerated as provided in
Article 6 of the Indenture for the purposes of its Subsidiary Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Obligations 
  

 D-1 

 guaranteed thereby, and (b) in the event of any declaration of acceleration of such Obligations as provided in Article 6 of the
Indenture, such Obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantor for the purpose of its Subsidiary Guarantee. 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 obligations of the Guarantors to the Holders and to the Trustee pursuant to the Subsidiary Guarantees and the Indenture are expressly set forth in Article 10 of
the Indenture, and reference is hereby made to such Indenture for the precise terms of the Subsidiary Guarantees. The terms of Article 10 of the Indenture are incorporated herein by reference. The Subsidiary Guarantees are subject to release as and
to the extent provided in Sections 10.04 and 10.05 of the Indenture. 
  
 Each Subsidiary Guarantee is a continuing guarantee and shall remain in full force and effect and shall be binding upon each Guarantor and its respective successors and assigns to the extent set forth in the Indenture until full and final
payment of all of the Company’s Obligations under the Notes and the Indenture and shall inure to the benefit of the successors and assigns of the Trustee and the Holders and, in the event of any transfer or assignment of rights by any Holder or
the Trustee, the rights and privileges conferred in the Indenture upon that party shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions hereof. Each Subsidiary Guarantee is a guarantee of
payment and not a guarantee of collection. 
  
 For purposes hereof, each
Guarantor’s liability under its Subsidiary Guarantee shall be limited in amount as provided in Section 10.06 of the Indenture. 
  
 Capitalized terms used herein have the same meanings given in the Indenture unless otherwise indicated.

 2. Registration Under the Securities Act. 
  
 (a) Except as set forth in Section 2(b) below, the Company agrees to file under the Securities Act, as soon as practicable, but no later than 90
days after the Closing Date, a registration statement relating to an offer to exchange (such registration statement, the “Exchange Registration Statement”, and such offer, the “Exchange Offer”) any and all of the Securities for a
like aggregate principal amount of debt securities issued by the Company and guaranteed by the Guarantors, which debt securities and guarantees are substantially identical to the Securities and the related Guarantees, respectively (and are entitled
to the benefits of a trust indenture which is substantially identical to the Indenture or is the Indenture and which has been qualified under the Trust Indenture Act), except that they have been registered pursuant to an effective registration
statement under the Securities Act and do not contain provisions for the Special Interest contemplated in Section 2(c) below (such new debt securities hereinafter called “Exchange Securities”). The Company agrees to use its reasonable best
efforts to cause the Exchange Registration Statement to become effective under the Securities Act as soon as practicable, but no later than 180 days after the Closing Date. The Exchange Offer will be registered under the Securities Act on the
appropriate form and will comply with all applicable tender offer rules and regulations under the Exchange Act. The Company further agrees to use its reasonable best efforts to commence and complete the Exchange Offer promptly, but no later than 30
days after such registration statement has become effective, hold the Exchange Offer open for at least 20 business days and exchange Exchange Securities for all Registrable Securities that have been validly tendered and not validly withdrawn on or
prior to the expiration of the Exchange Offer. The Exchange Offer will be deemed to have been “completed” only if the debt securities and related guarantees received by holders, other than Restricted Holders, in the Exchange Offer for
Registrable Securities are, upon receipt, transferable by each such holder without restriction under the Securities Act and the Exchange Act and without material restrictions under the blue sky or securities laws of a substantial majority of the
States of the United States of America. The Exchange Offer shall be deemed to have been completed upon the earlier to occur of (i) the Company having exchanged the Exchange Securities for all outstanding Registrable Securities pursuant to the
Exchange Offer and (ii) the Company having exchanged, pursuant to the Exchange Offer, Exchange Securities for 
  

 4 

 all Registrable Securities that have been validly tendered and not validly withdrawn before the expiration of the
Exchange Offer. The Company agrees (x) to include in the Exchange Registration Statement a prospectus for use in any resales by any holder of Exchange Securities that is a broker-dealer and (y) to keep such Exchange Registration Statement effective
for a period (the “Resale Period”) beginning when Exchange Securities are first issued in the Exchange Offer and ending upon the earlier of the expiration of the 180th day after the Exchange Offer has been completed or such time as such
broker-dealers no longer own any Registrable Securities. With respect to such Exchange Registration Statement, such holders shall have the benefit of the rights of indemnification and contribution set forth in Sections 6(a), (c), (d) and (e) hereof.

  
 (b) If (i) on or prior to the time the Exchange Offer
is completed existing Commission interpretations are changed such that the debt securities or the related guarantees received by holders other than Restricted Holders in the Exchange Offer for Registrable Securities are not or would not be, upon
receipt, transferable by each such holder without restriction under the Securities Act, (ii) the Exchange Offer has not been completed within 210 days following the Closing Date or (iii) the Exchange Offer is not available to any holder of the
Securities, the Company shall, in lieu of (or, in the case of clause (iii), in addition to) conducting the Exchange Offer contemplated by Section 2(a), file under the Securities Act as soon as practicable, but no later than 30 days after the time
such obligation to file arises, a “shelf” registration statement providing for the registration of, and the sale on a continuous or delayed basis by the holders of, all of the Registrable Securities, pursuant to Rule 415 or any similar
rule that may be adopted by the Commission (such filing, the “Shelf Registration” and such registration statement, the “Shelf Registration Statement”). The Company agrees to use its reasonable best efforts (x) to cause the Shelf
Registration Statement to become or be declared effective no later than 120 days after such Shelf Registration Statement is filed and to keep such Shelf Registration Statement continuously effective for a period ending on the earlier of the second
anniversary of the Effective Time or such time as there are no longer any Registrable Securities outstanding, provided, however, that no holder shall be entitled to be named as a selling securityholder in the Shelf Registration
Statement or to use the prospectus forming a part thereof for resales of Registrable Securities unless such holder is an Electing Holder, and (y) after the Effective Time of the Shelf Registration Statement, promptly upon the request of any holder
of Registrable Securities that is not then an Electing Holder, to take any action reasonably necessary to enable such holder to use the prospectus forming a part thereof for resales of Registrable Securities, including, without limitation, any
action necessary to identify such holder as a selling securityholder in the Shelf Registration Statement, provided, however, that nothing in this Clause (y) shall relieve any such holder of the obligation to return a completed and signed
Notice and Questionnaire to the Company in accordance with Section 3(d)(iii) hereof. The Company further agrees to supplement or make amendments to the Shelf Registration Statement, as and when required by the rules, regulations or instructions
applicable to the registration form used by the Company for such Shelf Registration Statement or by the Securities Act or rules and regulations thereunder for shelf registration, and the Company agrees to furnish to each Electing Holder copies of
any such supplement or amendment prior to its being used or promptly following its filing with the Commission. 
  
 (c) In the event that (i) the Company has not filed the Exchange Registration Statement or Shelf Registration Statement on or before the date on
which such registration statement is required to be filed pursuant to Section 2(a) or 2(b), respectively, or (ii) such Exchange Registration Statement or Shelf Registration Statement has not become effective or been declared effective by the
Commission on or before the date on which such registration 
  

 5 

 statement is required to become or be declared effective pursuant to Section 2(a) or 2(b), respectively, or (iii)
the Exchange Offer has not been completed within 30 days after the initial effective date of the Exchange Registration Statement relating to the Exchange Offer (if the Exchange Offer is then required to be made) or (iv) any Exchange Registration
Statement or Shelf Registration Statement required by Section 2(a) or 2(b) hereof is filed and declared effective but shall thereafter either be withdrawn by the Company or shall become subject to an effective stop order issued pursuant to Section
8(d) of the Securities Act suspending the effectiveness of such registration statement (except as specifically permitted herein) without being succeeded immediately by an additional registration statement or post-effective amendment filed and
declared effective (each such event referred to in clauses (i) through (iv), a “Registration Default” and each period during which a Registration Default has occurred and is continuing, a “Registration Default Period”), then, as
liquidated damages for such Registration Default, subject to the provisions of Section 9(b), special interest (“Special Interest”), in addition to the Base Interest, shall accrue on the outstanding Securities at a per annum rate of 0.25%
for the first 90 days of the Registration Default Period, at a per annum rate of 0.50% for the second 90 days of the Registration Default Period, at a per annum rate of 0.75% for the third 90 days of the Registration Default Period and at a per
annum rate of 1.0% thereafter for the remaining portion of the Registration Default Period. 
  
 (d) The Company shall take, and shall cause each Guarantor to take, all actions necessary or advisable to be taken by it to ensure that the
transactions contemplated herein are effected as so contemplated, including all actions necessary or desirable to register the Guarantees under the registration statement contemplated in Section 2(a) or 2(b) hereof, as applicable. 
  
 (e) Any reference herein to a registration statement as of any time
shall be deemed to include any document incorporated, or deemed to be incorporated, therein by reference as of such time and any reference herein to any post-effective amendment to a registration statement as of any time shall be deemed to include
any document incorporated, or deemed to be incorporated, therein by reference as of such time. 
  
 3. Registration Procedures. 
  
 If the Company files a registration statement pursuant to Section 2(a) or Section 2(b), the following provisions shall apply: 
  
 (a) At or before the Effective Time of the Exchange Offer or the Shelf
Registration, as the case may be, the Company shall qualify the Indenture under the Trust Indenture Act. 
  
 (b) In the event that such qualification would require the appointment of a new trustee under the Indenture, the Company shall appoint a new trustee
thereunder pursuant to the applicable provisions of the Indenture. 
  
 (c) In connection with the Company’s obligations with respect to the registration of Exchange Securities as contemplated by Section 2(a) (the “Exchange Registration”), if applicable, the Company shall, as soon as
practicable (or as otherwise specified): 
  
 (i) prepare
and file with the Commission, as soon as practicable but no later than 90 days after the Closing Date, an Exchange Registration Statement on any form which may be utilized by the Company and which shall permit the Exchange Offer and resales of
Exchange Securities by broker-dealers during the Resale Period 
  

 6 

 to be effected as contemplated by Section 2(a), and use its reasonable best efforts to cause such Exchange
Registration Statement to become effective as soon as practicable thereafter, but no later than 180 days after the Closing Date; 
  
 (ii) as soon as practicable prepare and file with the Commission such amendments and supplements to such Exchange Registration Statement and the
prospectus included therein as may be necessary to effect and maintain the effectiveness of such Exchange Registration Statement for the periods and purposes contemplated in Section 2(a) hereof and as may be required by the applicable rules and
regulations of the Commission and the instructions applicable to the form of such Exchange Registration Statement, and promptly provide each broker-dealer holding Exchange Securities with such number of copies of the prospectus included therein (as
then amended or supplemented), in conformity in all material respects with the requirements of the Securities Act and the Trust Indenture Act and the rules and regulations of the Commission thereunder, as such broker-dealer reasonably may request
prior to the expiration of the Resale Period, for use in connection with resales of Exchange Securities; 
  
 (iii) promptly notify each broker-dealer that has requested or been provided, by or on behalf of the Company, copies of the prospectus included in
the Registration Statement, and confirm such advice in writing, (A) when such Exchange Registration Statement or the prospectus included therein or any prospectus amendment or supplement or post-effective amendment has been filed, and, with respect
to such Exchange Registration Statement or any post-effective amendment, when the same has become effective, (B) of any comments by the Commission and by the blue sky or securities commissioner or regulator of any state with respect thereto or any
request by the Commission for amendments or supplements to such Exchange Registration Statement or prospectus or for additional information, (C) of the issuance by the Commission of any stop order suspending the effectiveness of such Exchange
Registration Statement or the initiation or threatening of any proceedings for that purpose, (D) if at any time prior to consummation of the Exchange Offer the representations and warranties of the Company contemplated by Section 5 cease to be true
and correct in all material respects, (E) of the receipt by the Company of any notification with respect to the suspension of the qualification of the Exchange Securities for sale in any jurisdiction or the initiation or threatening of any
proceeding for such purpose, or (F) at any time during the Resale Period when a prospectus is required to be delivered under the Securities Act, that such Exchange Registration Statement, prospectus, prospectus amendment or supplement or
post-effective amendment does not conform in all material respects to the applicable requirements of the Securities Act and the Trust Indenture Act and the rules and regulations of the Commission thereunder or contains an untrue statement of a
material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing; 
  
 (iv) in the event that the Company would be required, pursuant to Section 3(e)(iii)(F) above, to notify any
broker-dealers holding Exchange Securities, without delay prepare and furnish to each such holder a reasonable number of copies of a prospectus supplemented or amended so that, as thereafter delivered to purchasers of such Exchange Securities during
the Resale Period, such prospectus shall conform in all material respects to the applicable requirements of the Securities Act and the Trust Indenture Act and the rules and regulations of the Commission 
  

 7 

 thereunder and shall not contain an untrue statement of a material fact or omit to state a material fact required
to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing;

and all other actions as may be reasonably necessary or advisable to enable each broker-dealer holding Exchange Securities to consummate the disposition thereof in such jurisdictions; provided, however, that neither the Company nor any
Guarantor shall be required for any such purpose to (1) qualify as a foreign corporation in any jurisdiction wherein it would not otherwise be required to qualify but for the requirements of this Section 3(c)(vi), (2) consent to general service of
process in any such jurisdiction or (3) make any changes to its certificate of incorporation, by-laws or other organizational document or to any agreement between it and its stockholders or other equity interest holders;

Statement, an earning statement of the Company and its subsidiaries complying with Section 11(a) of the Securities Act (including, at the option of the Company, Rule 158 thereunder).

not misleading in light of the circumstances then existing;

which notices shall contain the text of the amendment or waiver proposed or effected, as the case may be; 
  
 (xix) in the event that any broker-dealer registered under the Exchange Act shall underwrite any Registrable Securities or participate as a member
of an underwriting syndicate or selling group or “assist in the distribution” (within the meaning of the Conduct Rules (the “Conduct Rules) of the National Association of Securities Dealers, Inc. (“NASD”) or any successor

the requirements of such Conduct Rules, including by (A) if such Conduct Rules shall so require, engaging a “qualified independent underwriter” (as defined in such Conduct Rules) to participate in the preparation of the Shelf Registration
Statement relating to such Registrable Securities, to exercise usual standards of due diligence in respect thereto and, if any portion of the offering contemplated by such Shelf Registration Statement is an underwritten offering or is made through a
placement or sales agent, to recommend the yield of such Registrable Securities, (B) indemnifying any such qualified independent underwriter to the extent of the indemnification of underwriters provided in Section 6 hereof (or to such other

subsidiaries complying with Section 11(a) of the Securities Act (including, at the option of the Company, Rule 158 thereunder). 
  
 (e) In the event that the Company would be required, pursuant to Section 3(d)(viii)(F) above, to notify the Electing Holders, the placement or sales

number of copies of a prospectus supplemented or 
  

 14 

 amended so that, as thereafter delivered to purchasers of Registrable Securities, such prospectus shall conform in
all material respects to the applicable requirements of the Securities Act and the Trust Indenture Act and the rules and regulations of the Commission thereunder and shall not contain an untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing. Each Electing Holder agrees that upon receipt of any notice from the Company pursuant to Section
3(d)(viii)(F) hereof, such Electing Holder shall forthwith discontinue the disposition of Registrable Securities pursuant to the Shelf Registration Statement applicable to such Registrable Securities until such Electing Holder shall have received
copies of such amended or supplemented prospectus, and if so directed by the Company, such Electing Holder shall deliver to the Company (at the Company’s expense) all copies, other than permanent file copies which shall not be distributed, then
in such Electing Holder’s possession of the prospectus covering such Registrable Securities at the time of receipt of such notice. 
  
 (f) In the event of a Shelf Registration, in addition to the information required to be provided by each Electing Holder in its Notice and
Questionnaire, the Company may require such Electing Holder to furnish to the Company such additional information regarding such Electing Holder and such Electing Holder’s intended method of distribution of Registrable Securities as may be
required in order to comply with the Securities Act. Each such Electing Holder agrees to notify the Company as promptly as practicable of any inaccuracy or change in information previously furnished by such Electing Holder to the Company or of the
occurrence of any event in either case as a result of which any prospectus relating to such Shelf Registration contains or would contain an untrue statement of a material fact regarding such Electing Holder or such Electing Holder’s intended
method of disposition of such Registrable Securities or omits to state any material fact regarding such Electing Holder or such Electing Holder’s intended method of disposition of such Registrable Securities required to be stated therein or
necessary to make the statements therein not misleading in light of the circumstances then existing, and promptly to furnish to the Company any additional information required to correct and update any previously furnished information or required so
that such prospectus shall not contain, with respect to such Electing Holder or the disposition of such Registrable Securities, an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to
make the statements therein not misleading in light of the circumstances then existing. 
  
 (g) Until the expiration of two years after the Closing Date, the Company will not, and will not permit any of its “affiliates” (as
defined in Rule 144) to, resell any of the Securities that have been reacquired by any of them except pursuant to an effective registration statement under the Securities Act. 
  
 4. Registration Expenses.

promptly after receipt of a request therefor. Notwithstanding the foregoing, the holders of the Registrable Securities being registered shall pay all agency fees and commissions and underwriting discounts and commissions attributable to the sale of
such Registrable Securities and the fees and disbursements of any counsel or other advisors or experts retained by such holders (severally or jointly), other than the counsel and experts specifically referred to above. 
  
 5. Representations and Warranties. 
  
 The Company represents and warrants to, and agrees with, each Purchaser and each of
the holders from time to time of Registrable Securities that: 
  
 (a) Each registration statement covering Registrable Securities and each prospectus (including any preliminary or summary prospectus) contained therein or furnished pursuant to Section 3(c) or Section 3(d) hereof and any further amendments
or supplements to any such registration statement or prospectus, when it becomes effective or is filed with the Commission, as the case may be, and, in the case of an underwritten offering of Registrable Securities, at the time of the closing under
the underwriting agreement relating thereto, will conform in all material respects to the requirements of the Securities Act and the Trust Indenture Act and the rules and regulations of the Commission thereunder and will not contain an untrue
statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading; and at all times subsequent to the Effective Time when a prospectus would be required to be
delivered under the Securities Act, other than from (i) such time as a notice has been given to holders 
  

 16 

 of Registrable Securities pursuant to Section 3(c)(iii)(F) or Section 3(d)(viii)(F) hereof until (ii) such time as
the Company furnishes an amended or supplemented prospectus pursuant to Section 3(c)(iv) or Section 3(e) hereof, each such registration statement, and each prospectus (including any summary prospectus) contained therein or furnished pursuant to
Section 3(c) or Section 3(d) hereof, as then amended or supplemented, will conform in all material respects to the requirements of the Securities Act and the Trust Indenture Act and the rules and regulations of the Commission thereunder and will not
contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing; provided, however, that
this representation and warranty shall not apply to any statements or omissions made in reliance upon and in conformity with information furnished in writing to the Company by a holder of Registrable Securities expressly for use therein. 

 
 (b) Any documents incorporated by reference in any prospectus
referred to in Section 5(a) hereof, when they become or became effective or are or were filed with the Commission, as the case may be, will conform or conformed in all material respects to the requirements of the Securities Act or the Exchange Act,
as applicable, and none of such documents will contain or contained an untrue statement of a material fact or will omit or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading;
provided, however, that this representation and warranty shall not apply to any statements or omissions made in reliance upon and in conformity with information furnished in writing to the Company by a holder of Registrable Securities
expressly for use therein. 
  
 (c) The compliance by the
Company with all of the provisions of this Exchange and Registration Rights Agreement and the consummation of the transactions herein contemplated will not conflict with or result in a breach of any of the terms or provisions of, or constitute a
default under, any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to which the Company or any subsidiary of the Company is a party or by which the Company or any subsidiary of the Company is bound or to which any
of the property or assets of the Company or any subsidiary of the Company is subject, other than any such conflict, breach or default that, individually or in the aggregate, would not have a Material Adverse Effect (as such term is defined in the
Purchase Agreement); nor will such action result in any violation of the provisions of the certificate of incorporation, by-laws or other organizational document of the Company or any Guarantor; nor will such action result in any violation of any
statute or any order, rule or regulation of any court or governmental agency or body having jurisdiction over the Company or any subsidiary of the Company or any of their properties, other than any such violation that, individually or in the

Guarantors of the transactions contemplated by this Exchange and Registration Rights Agreement, except the registration under the Securities Act of the Securities and the declaration of the effectiveness of any related registration statement,

the Securities. 
  
 (d) This Exchange and Registration
Rights Agreement has been duly authorized, executed and delivered by the Company and the Guarantors. 
  

 17 

 6. Indemnification. 
  
 (a) Indemnification by the Company and the Guarantors. The Company and the Guarantors, jointly and severally,
will indemnify and hold harmless each of the holders of Registrable Securities included in an Exchange Registration Statement, each of the Electing Holders of Registrable Securities included in a Shelf Registration Statement and each person who
participates as a placement or sales agent or as an underwriter in any offering or sale of such Registrable Securities against any losses, claims, damages or liabilities, joint or several, to which such holder, agent or underwriter may become
subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any
Exchange Registration Statement or Shelf Registration Statement, as the case may be, under which such Registrable Securities were registered under the Securities Act, or any preliminary, final or summary prospectus contained therein or furnished by
the Company to any such holder, Electing Holder, agent or underwriter, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and will reimburse such holder, such Electing Holder, such agent and such underwriter for any legal or other expenses reasonably incurred by them in connection with investigating or defending
any such action or claim as such expenses are incurred; provided, however, that neither the Company nor any Guarantor shall be liable to any such person in any such case to the extent that any such loss, claim, damage or liability arises out
of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in such registration statement, or preliminary, final or summary prospectus, or amendment or supplement thereto, in reliance upon and in
conformity with written information furnished to the Company by such person expressly for use therein. 
  
 (b) Indemnification by the Holders and any Agents and Underwriters. The Company may require, as a condition to including any Registrable
Securities in any registration statement filed pursuant to Section 2(b) hereof and to entering into any underwriting agreement with respect thereto, that the Company shall have received an undertaking reasonably satisfactory to it from the Electing
Holder of such Registrable Securities and from each underwriter named in any such underwriting agreement, severally and not jointly, to (i) indemnify and hold harmless the Company, the Guarantors, and all other holders of Registrable Securities,
against any losses, claims, damages or liabilities to which the Company, the Guarantors or such other holders of Registrable Securities may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities
(or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in such registration statement, or any preliminary, final or summary prospectus contained therein or
furnished by the Company to any such Electing Holder, agent or underwriter, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with
written information furnished to the Company by such Electing Holder or underwriter expressly for use therein, and (ii) reimburse the Company and the Guarantors for any legal or other expenses reasonably incurred by the Company and the Guarantors in
connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that no such Electing Holder 
  

 18 

 shall be required to undertake liability to any person under this Section 6(b) for any amounts in excess of the
dollar amount of the proceeds to be received by such Electing Holder from the sale of such Electing Holder’s Registrable Securities pursuant to such registration. 
  
 (c) Notices of Claims, Etc. Promptly after receipt by an indemnified party under subsection (a) or (b) above of
written notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against an indemnifying party pursuant to the indemnification provisions of or contemplated by this Section 6, notify such
indemnifying party in writing of the commencement of such action; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under the indemnification
provisions of or contemplated by Section 6(a) or 6(b) hereof. In case any such action shall be brought against any indemnified party and it shall notify an indemnifying party of the commencement thereof, such indemnifying party shall be entitled to
participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with a single counsel (in addition to any local counsel) reasonably satisfactory to such
indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, such
indemnifying party shall not be liable to such indemnified party for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than
reasonable costs of investigation. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action
or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an
unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of any indemnified party.

  
 (d) Contribution. If for any reason the
indemnification provisions contemplated by Section 6(a) or Section 6(b) are unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to
therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect
the relative fault of the indemnifying party and the indemnified party in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant
equitable considerations. The relative fault of such indemnifying party and indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or omission or alleged omission
to state a material fact relates to information supplied by such indemnifying party or by such indemnified party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or
omission. The parties hereto agree that it would not be just and equitable if contributions pursuant to this Section 6(d) were determined by pro rata allocation (even if the holders or any agents or underwriters or all of them were treated as one
entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 6(d). The amount paid or payable by an indemnified party as a result of the losses, claims,
damages, or liabilities (or 
  

 19 

 actions in respect thereof) referred to above shall be deemed to include any legal or other fees or expenses
reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 6(d), no holder shall be required to contribute any amount in excess of the amount
by which the dollar amount of the proceeds received by such holder from the sale of any Registrable Securities (after deducting any fees, discounts and commissions applicable thereto) exceeds the amount of any damages which such holder has otherwise
been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission, and no underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Registrable
Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or
alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The
holders’ and any underwriters’ obligations in this Section 6(d) to contribute shall be several in proportion to the principal amount of Registrable Securities registered or underwritten, as the case may be, by them and not joint.

  
 (e) The obligations of the Company and the Guarantors
under this Section 6 shall be in addition to any liability which the Company or the Guarantors may otherwise have and shall extend, upon the same terms and conditions, to each officer, director and partner of each holder, agent and underwriter and
each person, if any, who controls any holder, agent or underwriter within the meaning of the Securities Act; and the obligations of the holders and any agents or underwriters contemplated by this Section 6 shall be in addition to any liability which
the respective holder, agent or underwriter may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Company or any Guarantor (including any person who, with his consent, is named in any

Indenture. Each Security is entitled to the benefit of the guarantees provided for in the Indenture (the “Guarantees”) and, unless the context otherwise requires, any reference herein to a “Security,” an “Exchange
Security” or a “Registrable Security” shall include a reference to the related Guarantees.

 2. Registration Under the Securities Act. 
  
 (a) Except as set forth in Section 2(b) below, the Company agrees to file under the Securities Act, as soon as practicable, but no later than 90
days after the Closing Date, a registration statement relating to an offer to exchange (such registration statement, the “Exchange Registration Statement”, and such offer, the “Exchange Offer”) any and all of the Securities for a
like aggregate principal amount of debt securities issued by the Company and guaranteed by the Guarantors, which debt securities and guarantees are substantially identical to the Securities and the related Guarantees, respectively (and are entitled
to the benefits of a trust indenture which is substantially identical to the Indenture or is the Indenture and which has been qualified under the Trust Indenture Act), except that they have been registered pursuant to an effective registration
statement under the Securities Act and do not contain provisions for the Special Interest contemplated in Section 2(c) below (such new debt securities hereinafter called “Exchange Securities”). The Company agrees to use its reasonable best
efforts to cause the Exchange Registration Statement to become effective under the Securities Act as soon as practicable, but no later than 180 days after the Closing Date. The Exchange Offer will be registered under the Securities Act on the
appropriate form and will comply with all applicable tender offer rules and regulations under the Exchange Act. The Company further agrees to use its reasonable best efforts to commence and complete the Exchange Offer promptly, but no later than 30
days after such registration statement has become effective, hold the Exchange Offer open for at least 20 business days and exchange Exchange Securities for all Registrable Securities that have been validly tendered and not validly withdrawn on or
prior to the expiration of the Exchange Offer. The Exchange Offer will be deemed to have been “completed” only if the debt securities and related guarantees received by holders, other than Restricted Holders, in the Exchange Offer for
Registrable Securities are, upon receipt, transferable by each such holder without restriction under the Securities Act and the Exchange Act and without material restrictions under the blue sky or securities laws of a substantial majority of the
States of the United States of America. The Exchange Offer shall be deemed to have been completed upon the earlier to occur of (i) the Company having exchanged the Exchange Securities for all outstanding Registrable Securities pursuant to the
Exchange Offer and (ii) the Company having exchanged, pursuant to the Exchange Offer, Exchange Securities for 
  

 4 

 all Registrable Securities that have been validly tendered and not validly withdrawn before the expiration of the
Exchange Offer. The Company agrees (x) to include in the Exchange Registration Statement a prospectus for use in any resales by any holder of Exchange Securities that is a broker-dealer and (y) to keep such Exchange Registration Statement effective
for a period (the “Resale Period”) beginning when Exchange Securities are first issued in the Exchange Offer and ending upon the earlier of the expiration of the 180th day after the Exchange Offer has been completed or such time as such
broker-dealers no longer own any Registrable Securities. With respect to such Exchange Registration Statement, such holders shall have the benefit of the rights of indemnification and contribution set forth in Sections 6(a), (c), (d) and (e) hereof.

  
 (b) If (i) on or prior to the time the Exchange Offer
is completed existing Commission interpretations are changed such that the debt securities or the related guarantees received by holders other than Restricted Holders in the Exchange Offer for Registrable Securities are not or would not be, upon
receipt, transferable by each such holder without restriction under the Securities Act, (ii) the Exchange Offer has not been completed within 210 days following the Closing Date or (iii) the Exchange Offer is not available to any holder of the
Securities, the Company shall, in lieu of (or, in the case of clause (iii), in addition to) conducting the Exchange Offer contemplated by Section 2(a), file under the Securities Act as soon as practicable, but no later than 30 days after the time
such obligation to file arises, a “shelf” registration statement providing for the registration of, and the sale on a continuous or delayed basis by the holders of, all of the Registrable Securities, pursuant to Rule 415 or any similar
rule that may be adopted by the Commission (such filing, the “Shelf Registration” and such registration statement, the “Shelf Registration Statement”). The Company agrees to use its reasonable best efforts (x) to cause the Shelf
Registration Statement to become or be declared effective no later than 120 days after such Shelf Registration Statement is filed and to keep such Shelf Registration Statement continuously effective for a period ending on the earlier of the second
anniversary of the Effective Time or such time as there are no longer any Registrable Securities outstanding, provided, however, that no holder shall be entitled to be named as a selling securityholder in the Shelf Registration
Statement or to use the prospectus forming a part thereof for resales of Registrable Securities unless such holder is an Electing Holder, and (y) after the Effective Time of the Shelf Registration Statement, promptly upon the request of any holder
of Registrable Securities that is not then an Electing Holder, to take any action reasonably necessary to enable such holder to use the prospectus forming a part thereof for resales of Registrable Securities, including, without limitation, any
action necessary to identify such holder as a selling securityholder in the Shelf Registration Statement, provided, however, that nothing in this Clause (y) shall relieve any such holder of the obligation to return a completed and signed
Notice and Questionnaire to the Company in accordance with Section 3(d)(iii) hereof. The Company further agrees to supplement or make amendments to the Shelf Registration Statement, as and when required by the rules, regulations or instructions
applicable to the registration form used by the Company for such Shelf Registration Statement or by the Securities Act or rules and regulations thereunder for shelf registration, and the Company agrees to furnish to each Electing Holder copies of
any such supplement or amendment prior to its being used or promptly following its filing with the Commission. 
  
 (c) In the event that (i) the Company has not filed the Exchange Registration Statement or Shelf Registration Statement on or before the date on
which such registration statement is required to be filed pursuant to Section 2(a) or 2(b), respectively, or (ii) such Exchange Registration Statement or Shelf Registration Statement has not become effective or been declared effective by the
Commission on or before the date on which such registration 
  

 5 

 statement is required to become or be declared effective pursuant to Section 2(a) or 2(b), respectively, or (iii)
the Exchange Offer has not been completed within 30 days after the initial effective date of the Exchange Registration Statement relating to the Exchange Offer (if the Exchange Offer is then required to be made) or (iv) any Exchange Registration
Statement or Shelf Registration Statement required by Section 2(a) or 2(b) hereof is filed and declared effective but shall thereafter either be withdrawn by the Company or shall become subject to an effective stop order issued pursuant to Section
8(d) of the Securities Act suspending the effectiveness of such registration statement (except as specifically permitted herein) without being succeeded immediately by an additional registration statement or post-effective amendment filed and
declared effective (each such event referred to in clauses (i) through (iv), a “Registration Default” and each period during which a Registration Default has occurred and is continuing, a “Registration Default Period”), then, as
liquidated damages for such Registration Default, subject to the provisions of Section 9(b), special interest (“Special Interest”), in addition to the Base Interest, shall accrue on the outstanding Securities at a per annum rate of 0.25%
for the first 90 days of the Registration Default Period, at a per annum rate of 0.50% for the second 90 days of the Registration Default Period, at a per annum rate of 0.75% for the third 90 days of the Registration Default Period and at a per
annum rate of 1.0% thereafter for the remaining portion of the Registration Default Period. 
  
 (d) The Company shall take, and shall cause each Guarantor to take, all actions necessary or advisable to be taken by it to ensure that the
transactions contemplated herein are effected as so contemplated, including all actions necessary or desirable to register the Guarantees under the registration statement contemplated in Section 2(a) or 2(b) hereof, as applicable. 
  
 (e) Any reference herein to a registration statement as of any time
shall be deemed to include any document incorporated, or deemed to be incorporated, therein by reference as of such time and any reference herein to any post-effective amendment to a registration statement as of any time shall be deemed to include
any document incorporated, or deemed to be incorporated, therein by reference as of such time. 
  
 3. Registration Procedures. 
  
 If the Company files a registration statement pursuant to Section 2(a) or Section 2(b), the following provisions shall apply: 
  
 (a) At or before the Effective Time of the Exchange Offer or the Shelf
Registration, as the case may be, the Company shall qualify the Indenture under the Trust Indenture Act. 
  
 (b) In the event that such qualification would require the appointment of a new trustee under the Indenture, the Company shall appoint a new trustee
thereunder pursuant to the applicable provisions of the Indenture. 
  
 (c) In connection with the Company’s obligations with respect to the registration of Exchange Securities as contemplated by Section 2(a) (the “Exchange Registration”), if applicable, the Company shall, as soon as

regulations of the Commission and the instructions applicable to the form of such Exchange Registration Statement, and promptly provide each broker-dealer holding Exchange Securities with such number of copies of the prospectus included therein (as
then amended or supplemented), in conformity in all material respects with the requirements of the Securities Act and the Trust Indenture Act and the rules and regulations of the Commission thereunder, as such broker-dealer reasonably may request

Registration Statement or the initiation or threatening of any proceedings for that purpose, (D) if at any time prior to consummation of the Exchange Offer the representations and warranties of the Company contemplated by Section 5 cease to be true
and correct in all material respects, (E) of the receipt by the Company of any notification with respect to the suspension of the qualification of the Exchange Securities for sale in any jurisdiction or the initiation or threatening of any
proceeding for such purpose, or (F) at any time during the Resale Period when a prospectus is required to be delivered under the Securities Act, that such Exchange Registration Statement, prospectus, prospectus amendment or supplement or
post-effective amendment does not conform in all material respects to the applicable requirements of the Securities Act and the Trust Indenture Act and the rules and regulations of the Commission thereunder or contains an untrue statement of a
material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing; 
  
 (iv) in the event that the Company would be required, pursuant to Section 3(e)(iii)(F) above, to notify any

the Resale Period, such prospectus shall conform in all material respects to the applicable requirements of the Securities Act and the Trust Indenture Act and the rules and regulations of the Commission

thereto, as amended from time to time) thereof, whether as a holder of such Registrable Securities or as an underwriter, a placement or sales agent or a broker or dealer in respect thereof, or otherwise, assist such broker-dealer in complying with
the requirements of such Conduct Rules, including by (A) if such Conduct Rules shall so require, engaging a “qualified independent underwriter” (as defined in such Conduct Rules) to participate in the preparation of the Shelf Registration
Statement relating to such Registrable Securities, to exercise usual standards of due diligence in respect thereto and, if any portion of the offering contemplated by such Shelf Registration Statement is an underwritten offering or is made through a
placement or sales agent, to recommend the yield of such Registrable Securities, (B) indemnifying any such qualified independent underwriter to the extent of the indemnification of underwriters provided in Section 6 hereof (or to such other
customary extent as may be requested by such underwriter), and (C) providing such information to such broker-dealer as may be required in order for such broker-dealer to comply with the requirements of the Conduct Rules; and 
  
 (xx) comply with all applicable rules and regulations of the
Commission, and make generally available to its securityholders as soon as practicable but in any event not later than eighteen months after the effective date of such Shelf Registration Statement, an earning statement of the Company and its
subsidiaries complying with Section 11(a) of the Securities Act (including, at the option of the Company, Rule 158 thereunder). 
  
 (e) In the event that the Company would be required, pursuant to Section 3(d)(viii)(F) above, to notify the Electing Holders, the placement or sales
agent, if any, therefor and the managing underwriters, if any, thereof, the Company shall without delay prepare and furnish to each of the Electing Holders, to each placement or sales agent, if any, and to each such underwriter, if any, a reasonable
number of copies of a prospectus supplemented or 
  

 14 

 amended so that, as thereafter delivered to purchasers of Registrable Securities, such prospectus shall conform in
all material respects to the applicable requirements of the Securities Act and the Trust Indenture Act and the rules and regulations of the Commission thereunder and shall not contain an untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing. Each Electing Holder agrees that upon receipt of any notice from the Company pursuant to Section
3(d)(viii)(F) hereof, such Electing Holder shall forthwith discontinue the disposition of Registrable Securities pursuant to the Shelf Registration Statement applicable to such Registrable Securities until such Electing Holder shall have received
copies of such amended or supplemented prospectus, and if so directed by the Company, such Electing Holder shall deliver to the Company (at the Company’s expense) all copies, other than permanent file copies which shall not be distributed, then
in such Electing Holder’s possession of the prospectus covering such Registrable Securities at the time of receipt of such notice. 
  
 (f) In the event of a Shelf Registration, in addition to the information required to be provided by each Electing Holder in its Notice and
Questionnaire, the Company may require such Electing Holder to furnish to the Company such additional information regarding such Electing Holder and such Electing Holder’s intended method of distribution of Registrable Securities as may be
required in order to comply with the Securities Act. Each such Electing Holder agrees to notify the Company as promptly as practicable of any inaccuracy or change in information previously furnished by such Electing Holder to the Company or of the
occurrence of any event in either case as a result of which any prospectus relating to such Shelf Registration contains or would contain an untrue statement of a material fact regarding such Electing Holder or such Electing Holder’s intended
method of disposition of such Registrable Securities or omits to state any material fact regarding such Electing Holder or such Electing Holder’s intended method of disposition of such Registrable Securities required to be stated therein or
necessary to make the statements therein not misleading in light of the circumstances then existing, and promptly to furnish to the Company any additional information required to correct and update any previously furnished information or required so
that such prospectus shall not contain, with respect to such Electing Holder or the disposition of such Registrable Securities, an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to
make the statements therein not misleading in light of the circumstances then existing. 
  
 (g) Until the expiration of two years after the Closing Date, the Company will not, and will not permit any of its “affiliates” (as
defined in Rule 144) to, resell any of the Securities that have been reacquired by any of them except pursuant to an effective registration statement under the Securities Act. 
  
 4. Registration Expenses. 
  
 The Company agrees to bear and to pay or cause to be paid promptly all expenses incident to the Company’s performance of or compliance with this Exchange and
Registration Rights Agreement, including (a) all Commission and any NASD registration, filing and review fees and expenses including fees and disbursements of counsel for the placement or sales agent or underwriters in connection with such

expenses and disbursements of any other persons, including special experts, retained by the Company in connection with such registration (collectively, the “Registration Expenses”). To the extent that any Registration Expenses are

promptly after receipt of a request therefor. Notwithstanding the foregoing, the holders of the Registrable Securities being registered shall pay all agency fees and commissions and underwriting discounts and commissions attributable to the sale of
such Registrable Securities and the fees and disbursements of any counsel or other advisors or experts retained by such holders (severally or jointly), other than the counsel and experts specifically referred to above. 
  
 5. Representations and Warranties. 
  
 The Company represents and warrants to, and agrees with, each Purchaser and each of
the holders from time to time of Registrable Securities that: 
  
 (a) Each registration statement covering Registrable Securities and each prospectus (including any preliminary or summary prospectus) contained therein or furnished pursuant to Section 3(c) or Section 3(d) hereof and any further amendments
or supplements to any such registration statement or prospectus, when it becomes effective or is filed with the Commission, as the case may be, and, in the case of an underwritten offering of Registrable Securities, at the time of the closing under
the underwriting agreement relating thereto, will conform in all material respects to the requirements of the Securities Act and the Trust Indenture Act and the rules and regulations of the Commission thereunder and will not contain an untrue
statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading; and at all times subsequent to the Effective Time when a prospectus would be required to be
delivered under the Securities Act, other than from (i) such time as a notice has been given to holders 
  

 16 

 of Registrable Securities pursuant to Section 3(c)(iii)(F) or Section 3(d)(viii)(F) hereof until (ii) such time as
the Company furnishes an amended or supplemented prospectus pursuant to Section 3(c)(iv) or Section 3(e) hereof, each such registration statement, and each prospectus (including any summary prospectus) contained therein or furnished pursuant to
Section 3(c) or Section 3(d) hereof, as then amended or supplemented, will conform in all material respects to the requirements of the Securities Act and the Trust Indenture Act and the rules and regulations of the Commission thereunder and will not
contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing; provided, however, that
this representation and warranty shall not apply to any statements or omissions made in reliance upon and in conformity with information furnished in writing to the Company by a holder of Registrable Securities expressly for use therein. 

 
 (b) Any documents incorporated by reference in any prospectus
referred to in Section 5(a) hereof, when they become or became effective or are or were filed with the Commission, as the case may be, will conform or conformed in all material respects to the requirements of the Securities Act or the Exchange Act,
as applicable, and none of such documents will contain or contained an untrue statement of a material fact or will omit or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading;
provided, however, that this representation and warranty shall not apply to any statements or omissions made in reliance upon and in conformity with information furnished in writing to the Company by a holder of Registrable Securities
expressly for use therein. 
  
 (c) The compliance by the
Company with all of the provisions of this Exchange and Registration Rights Agreement and the consummation of the transactions herein contemplated will not conflict with or result in a breach of any of the terms or provisions of, or constitute a
default under, any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to which the Company or any subsidiary of the Company is a party or by which the Company or any subsidiary of the Company is bound or to which any
of the property or assets of the Company or any subsidiary of the Company is subject, other than any such conflict, breach or default that, individually or in the aggregate, would not have a Material Adverse Effect (as such term is defined in the
Purchase Agreement); nor will such action result in any violation of the provisions of the certificate of incorporation, by-laws or other organizational document of the Company or any Guarantor; nor will such action result in any violation of any
statute or any order, rule or regulation of any court or governmental agency or body having jurisdiction over the Company or any subsidiary of the Company or any of their properties, other than any such violation that, individually or in the
aggregate, would not have a Material Adverse Effect; and no consent, approval, authorization, order, registration or qualification of or with any such court or governmental agency or body is required for the consummation by the Company and the
Guarantors of the transactions contemplated by this Exchange and Registration Rights Agreement, except the registration under the Securities Act of the Securities and the declaration of the effectiveness of any related registration statement,
qualification of the Indenture under the Trust Indenture Act and such consents, approvals, authorizations, registrations or qualifications as may be required under State securities or blue sky laws in connection with the offering and distribution of
the Securities. 
  
 (d) This Exchange and Registration
Rights Agreement has been duly authorized, executed and delivered by the Company and the Guarantors. 
  

 17 

 6. Indemnification. 
  
 (a) Indemnification by the Company and the Guarantors. The Company and the Guarantors, jointly and severally,
will indemnify and hold harmless each of the holders of Registrable Securities included in an Exchange Registration Statement, each of the Electing Holders of Registrable Securities included in a Shelf Registration Statement and each person who
participates as a placement or sales agent or as an underwriter in any offering or sale of such Registrable Securities against any losses, claims, damages or liabilities, joint or several, to which such holder, agent or underwriter may become
subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any
Exchange Registration Statement or Shelf Registration Statement, as the case may be, under which such Registrable Securities were registered under the Securities Act, or any preliminary, final or summary prospectus contained therein or furnished by
the Company to any such holder, Electing Holder, agent or underwriter, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and will reimburse such holder, such Electing Holder, such agent and such underwriter for any legal or other expenses reasonably incurred by them in connection with investigating or defending
any such action or claim as such expenses are incurred; provided, however, that neither the Company nor any Guarantor shall be liable to any such person in any such case to the extent that any such loss, claim, damage or liability arises out
of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in such registration statement, or preliminary, final or summary prospectus, or amendment or supplement thereto, in reliance upon and in
conformity with written information furnished to the Company by such person expressly for use therein. 
  
 (b) Indemnification by the Holders and any Agents and Underwriters. The Company may require, as a condition to including any Registrable
Securities in any registration statement filed pursuant to Section 2(b) hereof and to entering into any underwriting agreement with respect thereto, that the Company shall have received an undertaking reasonably satisfactory to it from the Electing
Holder of such Registrable Securities and from each underwriter named in any such underwriting agreement, severally and not jointly, to (i) indemnify and hold harmless the Company, the Guarantors, and all other holders of Registrable Securities,
against any losses, claims, damages or liabilities to which the Company, the Guarantors or such other holders of Registrable Securities may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities
(or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in such registration statement, or any preliminary, final or summary prospectus contained therein or
furnished by the Company to any such Electing Holder, agent or underwriter, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with
written information furnished to the Company by such Electing Holder or underwriter expressly for use therein, and (ii) reimburse the Company and the Guarantors for any legal or other expenses reasonably incurred by the Company and the Guarantors in
connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that no such Electing Holder 
  

 18 

 shall be required to undertake liability to any person under this Section 6(b) for any amounts in excess of the
dollar amount of the proceeds to be received by such Electing Holder from the sale of such Electing Holder’s Registrable Securities pursuant to such registration. 
  
 (c) Notices of Claims, Etc. Promptly after receipt by an indemnified party under subsection (a) or (b) above of
written notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against an indemnifying party pursuant to the indemnification provisions of or contemplated by this Section 6, notify such
indemnifying party in writing of the commencement of such action; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under the indemnification
provisions of or contemplated by Section 6(a) or 6(b) hereof. In case any such action shall be brought against any indemnified party and it shall notify an indemnifying party of the commencement thereof, such indemnifying party shall be entitled to
participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with a single counsel (in addition to any local counsel) reasonably satisfactory to such
indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, such
indemnifying party shall not be liable to such indemnified party for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than
reasonable costs of investigation. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action
or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an
unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of any indemnified party.

  
 (d) Contribution. If for any reason the
indemnification provisions contemplated by Section 6(a) or Section 6(b) are unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to
therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect
the relative fault of the indemnifying party and the indemnified party in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant
equitable considerations. The relative fault of such indemnifying party and indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or omission or alleged omission
to state a material fact relates to information supplied by such indemnifying party or by such indemnified party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or
omission. The parties hereto agree that it would not be just and equitable if contributions pursuant to this Section 6(d) were determined by pro rata allocation (even if the holders or any agents or underwriters or all of them were treated as one
entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 6(d). The amount paid or payable by an indemnified party as a result of the losses, claims,
damages, or liabilities (or 
  

 19 

 actions in respect thereof) referred to above shall be deemed to include any legal or other fees or expenses
reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 6(d), no holder shall be required to contribute any amount in excess of the amount
by which the dollar amount of the proceeds received by such holder from the sale of any Registrable Securities (after deducting any fees, discounts and commissions applicable thereto) exceeds the amount of any damages which such holder has otherwise
been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission, and no underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Registrable
Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or
alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The
holders’ and any underwriters’ obligations in this Section 6(d) to contribute shall be several in proportion to the principal amount of Registrable Securities registered or underwritten, as the case may be, by them and not joint.

  
 (e) The obligations of the Company and the Guarantors
under this Section 6 shall be in addition to any liability which the Company or the Guarantors may otherwise have and shall extend, upon the same terms and conditions, to each officer, director and partner of each holder, agent and underwriter and
each person, if any, who controls any holder, agent or underwriter within the meaning of the Securities Act; and the obligations of the holders and any agents or underwriters contemplated by this Section 6 shall be in addition to any liability which
the respective holder, agent or underwriter may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Company or any Guarantor (including any person who, with his consent, is named in any
registration statement as about to become a director of the Company or any Guarantor) and to each person, if any, who controls the Company within the meaning of the Securities Act. 
  
 7. Underwritten Offerings. 
  
 (a) Selection of Underwriters. If any of the Registrable Securities covered by the Shelf Registration are to be
sold pursuant to an underwritten offering, the managing underwriter or underwriters thereof shall be designated by Electing Holders holding at least a majority in aggregate principal amount of the Registrable Securities to be included in such
offering, provided that such designated managing underwriter or underwriters is or are reasonably acceptable to the Company. 
  
 (b) Participation by Holders. Each holder of Registrable Securities hereby agrees with each other such holder that no such holder may
participate in any underwritten offering hereunder unless such holder (i) agrees to sell such holder’s Registrable Securities on the basis provided in any underwriting arrangements approved by the persons entitled hereunder to approve such
arrangements and (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements. 
  

 20 

 8. Rule 144. 
  
 The Company covenants to the holders of Registrable Securities that to the extent it shall be required to do so under the Exchange Act, the Company shall timely
file the reports required to be filed by it under the Exchange Act or the Securities Act (including the reports under Section 13 and 15(d) of the Exchange Act referred to in subparagraph (c)(1) of Rule 144 adopted by the Commission under the
Securities Act) and the rules and regulations adopted by the Commission thereunder, and shall take such further action as any holder of Registrable Securities may reasonably request, all to the extent required from time to time to enable such holder
to sell Registrable Securities without registration under the Securities Act within the limitations of the exemption provided by Rule 144 under the Securities Act, as such Rule may be amended from time to time, or any similar or successor rule or
regulation hereafter adopted by the Commission. Upon the request of any holder of Registrable Securities in connection with that holder’s sale pursuant to Rule 144, the Company shall deliver to such holder a written statement as to whether it
has complied with such requirements. 
  
 9.
Miscellaneous. 
  
 (a) No Inconsistent
Agreements. The Company represents, warrants, covenants and agrees that it has not granted, and shall not grant, registration rights with respect to Registrable Securities or any other securities which would be inconsistent with the terms
contained in this Exchange and Registration Rights Agreement. 
  
 (b) Specific Performance. The parties hereto acknowledge that there would be no adequate remedy at law if the Company fails to perform any of its obligations hereunder and that the Purchasers and the holders from time to time of the
Registrable Securities may be irreparably harmed by any such failure, and accordingly agree that the Purchasers and such holders, in addition to any other remedy to which they may be entitled at law or in equity, shall be entitled to compel specific
performance of the obligations of the Company under this Exchange and Registration Rights Agreement in accordance with the terms and conditions of this Exchange and Registration Rights Agreement, in any court of the United States or any State
thereof having jurisdiction. 
  
 (c) Notices. All
notices, requests, claims, demands, waivers and other communications hereunder shall be in writing and shall be deemed to have been duly given when delivered by hand, if delivered personally or by courier, or three days after being deposited in the
mail (registered or certified mail, postage prepaid, return receipt requested) as follows: If to the Company, to it at 103 Northpark Boulevard, Suite 300, Covington, Louisiana 70433 and if to a holder, to the address of such holder set forth in the
security register or other records of the Company, or to such other address as the Company or any such holder may have furnished to the other in writing in accordance herewith, except that notices of change of address shall be effective only upon
receipt. 
  
 (d) Parties in Interest. All the terms
and provisions of this Exchange and Registration Rights Agreement shall be binding upon, shall inure to the benefit of and shall be enforceable by the parties hereto and the holders from time to time of the Registrable Securities and the respective
successors and assigns of the parties hereto and such holders. In the event that any transferee of any holder of Registrable Securities shall acquire Registrable Securities, in any manner, whether by gift, bequest, purchase, operation of law or
otherwise, such transferee shall, without any further writing or action of any kind, be deemed a beneficiary hereof for all purposes and such Registrable Securities shall be held 
  

 21 

 subject to all of the terms of this Exchange and Registration Rights Agreement, and by taking and holding such
Registrable Securities such transferee shall be entitled to receive the benefits of, and be conclusively deemed to have agreed to be bound by all of the applicable terms and provisions of this Exchange and Registration Rights Agreement. If the
Company shall so request, any such successor, assign or transferee shall agree in writing to acquire and hold the Registrable Securities subject to all of the applicable terms hereof. 
  
 (e) Survival. The respective indemnities, agreements, representations, warranties and each other provision set
forth in this Exchange and Registration Rights Agreement or made pursuant hereto shall remain in full force and effect regardless of any investigation (or statement as to the results thereof) made by or on behalf of any holder of Registrable
Securities, any director, officer or partner of such holder, any agent or underwriter or any director, officer or partner thereof, or any controlling person of any of the foregoing, and shall survive delivery of and payment for the Registrable
Securities pursuant to the Purchase Agreement and the transfer and registration of Registrable Securities by such holder and the consummation of an Exchange Offer. 
  
 (f) Governing Law. This Exchange and Registration Rights Agreement shall be
governed by and construed in accordance with the laws of the State of New York. 
  
 (g) Headings. The descriptive headings of the several Sections and paragraphs of this Exchange and Registration Rights Agreement are inserted
for convenience only, do not constitute a part of this Exchange and Registration Rights Agreement and shall not affect in any way the meaning or interpretation of this Exchange and Registration Rights Agreement. 
  
 (h) Entire Agreement; Amendments. This Exchange and
Registration Rights Agreement and the other writings referred to herein (including the Indenture and the form of Securities) or delivered pursuant hereto which form a part hereof contain the entire understanding of the parties with respect to its
subject matter. This Exchange and Registration Rights Agreement supersedes all prior agreements and understandings between the parties with respect to its subject matter. This Exchange and Registration Rights Agreement may be amended and the
observance of any term of this Exchange and Registration Rights Agreement may be waived (either generally or in a particular instance and either retroactively or prospectively) only by a written instrument duly executed by the Company and the
holders of at least a majority in aggregate principal amount of the Registrable Securities at the time outstanding. Each holder of any Registrable Securities at the time or thereafter outstanding shall be bound by any amendment or waiver effected
pursuant to this Section 9(h), whether or not any notice, writing or marking indicating such amendment or waiver appears on such Registrable Securities or is delivered to such holder. 
  
 (i) Inspection. For so long as this Exchange and Registration Rights Agreement shall be in effect, this
Exchange and Registration Rights Agreement and a complete list of the names and addresses of all the holders of Registrable Securities shall be made available for inspection and copying on any business day by any holder of Registrable Securities for
proper purposes only (which shall include any purpose related to the rights of the holders of Registrable Securities under the Securities, the Indenture and this Agreement) at the offices of the Company at the address thereof set forth in Section
9(c) above and at the office of the Trustee under the Indenture. 
  

 22 

 (j) Counterparts. This agreement may be executed by the parties in counterparts, each of
which shall be deemed to be an original, but all such respective counterparts shall together constitute one and the same instrument. 
  
 If the foregoing is in accordance with your understanding, please sign and return to us seven counterparts hereof (one for the Company, the
Guarantors and each of the representatives plus one for each counsel), and upon the acceptance hereof by you, on behalf of each of the Purchasers, this letter and such acceptance hereof shall constitute a binding agreement between each of the
Purchasers, the Guarantors and the Company. It is understood that your acceptance of this letter on behalf of each of the Purchasers is pursuant to the authority set forth in a form of Agreement among Purchasers, the form of which shall be submitted
