and ratable basis.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (i) | If:
| | --- | ---



| | (1) | the Issuers and the Guarantors determine that applicable laws or applicable interpretations of the staff of the SEC would not permit the consummation of the Exchange
Offer on or prior to the 30th Business Day following the Effectiveness Date;
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Section 3 shall apply to all Registrable Notes. Otherwise, upon consummation of the Exchange Offer in accordance with Section 2, the provisions of Section 3 shall apply solely with respect to Notes held by an Initial Purchaser as
contemplated by Section 2(i)(3) hereof, provided, in each case, that the relevant Initial Purchaser has duly notified the Issuers within six months of the Exchange Offer as required by Section 2(i)(3) above.



| | (a) | Initial Shelf Registration. The Issuers and the Guarantors shall use their commercially reasonable efforts to file with the SEC a Registration
Statement for an offering to be made on a continuous basis pursuant to Rule 415 covering all of the Registrable Notes (the Initial Shelf Registration). If the Issuers and the Guarantors have not yet filed an Exchange Registration

Shelf Registration Statement to be declared effective before the earliest of (i) the 270thday following the Closing Date and (ii) the 45thday following the consummation of the Exchange Offer. The Initial Shelf Registration shall be on the appropriate form permitting registration of such Registrable Notes for resale by Holders in the manner
or manners reasonably designated by them (including, without limitation, one or more underwritten offerings). The Issuers and the Guarantors shall use their commercially reasonable efforts to keep the Initial Shelf Registration effective under the
Securities Act until the date which is the earliest of (i) the one year anniversary of the Closing Date, (ii) the date when all of the Notes have been sold under the Shelf Registration Statement and (iii) the date when Holders, other
than Holders that are affiliates (as defined in Rule 144) of the Issuers, are able to sell such Notes without restriction, and without reliance as to the availability of current public information, pursuant to Rule 144 (the
Effectiveness Period).

| | (b) | Subsequent Shelf Registrations. If the Initial Shelf Registration or any Subsequent Shelf Registration (as defined below) ceases to be effective
for any reason at any time during the Effectiveness Period, the Issuers and the Guarantors shall use their commercially reasonable efforts to obtain the prompt withdrawal of any order suspending the effectiveness thereof, and in any event shall
within 60 days of such cessation of effectiveness amend such Shelf Registration in a manner to obtain the withdrawal of the order suspending the effectiveness thereof, or file an additional shelf Registration Statement pursuant to Rule
415 covering all of the Registrable Notes (a Subsequent Shelf Registration). If a Subsequent Shelf Registration is filed, the Issuers and the Guarantors shall use their commercially reasonable to cause the Subsequent Shelf
Registration to be declared effective as soon as practicable after such filing and to keep such Subsequent Shelf Registration continuously effective for the remainder of the Effectiveness Period (except that clause (ii) of the definition of
Effectiveness Period for such purposes shall mean the date when all of the Notes have been sold under a Shelf Registration Statement). As used herein the term Shelf Registration means the Initial Shelf Registration and any Subsequent

| | (c) | Supplements and Amendments. The Issuers and the Guarantors shall promptly supplement and amend any Shelf Registration if required by the rules, regulations or
instructions applicable to the registration form used for such Shelf Registration, if required by the Securities Act, or if reasonably requested in writing by the Holders of a majority in aggregate principal amount of the Registrable Notes covered

| | (d) | Provision of Information. No Holder of Registrable Notes shall be entitled to include any of its Registrable Notes in any Shelf Registration pursuant to this
Agreement unless such Holder furnishes to the Issuers, the Guarantors and the Trustee in writing, within 20 days after receipt of a written request therefor, such information as the Issuers, the Guarantors and the Trustee (after conferring with
counsel with regard to information relating to Holders that would be required by the SEC to be included in such Shelf Registration or Prospectus included therein) may reasonably request for inclusion in any Shelf Registration or Prospectus included
therein, and no such Holder shall be entitled to Additional Interest pursuant to Section 4 hereof unless and until such Holder shall have provided such information.

|4. | Additional Interest
|-- | -------------------



| | (a) | The Issuers and the Guarantors acknowledge and agree that the Holders will suffer damages if the Issuers or the Guarantors fail to fulfill their material obligations
under Section 2 or Section 3 hereof and that it would not be feasible to ascertain the extent of such damages with precision. Accordingly, if:
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (i) | (A) neither the Exchange Registration Statement nor a Shelf Registration is declared effective by the SEC on or prior to the Effectiveness Date or
(B) notwithstanding that the Issuers have consummated or will consummate an Exchange Offer, the Issuers and the Guarantors are required to file a Shelf Registration and such Shelf Registration is not declared effective by the SEC on or prior to
the 90th day following the date such Shelf Registration was filed; or
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | (A) the Issuers have not exchanged all Notes validly tendered in accordance with the terms of the Exchange Offer for Exchange Notes on or prior to the 30th Business Day
after the date on which the Exchange Registration Statement was declared effective or (B) if applicable, the Shelf Registration has been declared effective and such Shelf Registration ceases to be effective at any time prior to the
Effectiveness Period; provided that the Issuers and the Guarantors will be permitted to suspend the use of the prospectus that is part of the Shelf Registration if their management determines to do so for valid business reasons, including
circumstances relating to pending corporate developments and similar events or filings with the SEC, for a period not to exceed 45 days in any three-month period and not to exceed an aggregate of 90 days in any twelve-month period and without
specifying the nature of the event giving rise to a suspension in any notice of suspension provided to the Holders (each a Registration Default,),
| | ---- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

principal amount of the Notes at a rate of 0.25% per annum for the first 90 days commencing on the day following the Registration Default, and increasing to 1.00% thereafter, to but excluding the day on which the Registration Default has been
cured. Additional Interest will be paid semi-annually in arrears with the interest payment due on the first interest payment date following the date on which such Additional Interest begins to accrue; provided, however, that
(a) the Additional Interest on the Notes may not accrue under more than one of the foregoing clauses (i) and (ii) at any one time and in no event will Additional Interest accrue after the Effectiveness Period, (b) if a Holder is
not able to or does not provide the representations and information required in connection with a Shelf Registration in a timely manner and is therefore not named as a selling security holder in a Shelf Registration, the Holder will not be entitled
to receive any Additional Interest with respect to its Notes; and (c) the Issuers and the Guarantors will have no other liabilities with respect to any Registration Default.



| | (b) | The Issuers shall notify the Trustee within 5 Business Days after each and every date on which an event occurs in respect of which Additional Interest is required to be
paid (an Event Date). Any amounts of Additional Interest due pursuant to clause (a)(i) or (a)(ii) of this Section 4 will be payable in cash, on the dates and in the manner provided in the Indenture and whether or not any cash
interest would then be payable on such date, commencing with the first such semi-annual date occurring after any such Additional Interest commences to accrue.

thereby in accordance with the intended method or methods of disposition thereof, and pursuant thereto and in connection with any Registration Statement filed by the Issuers and the Guarantors hereunder, the Issuers and the Guarantors shall:

afforded a reasonable opportunity to review such documentation with respect to such Holders information or (ii) if a Holder, the Managing Underwriters, if any, or any of their respective counsel shall reasonably object in writing on a
timely basis to the information with respect to such Holders. An aforementioned party shall be deemed to have reasonably objected to such filing if such Registration Statement, amendment, Prospectus or supplement, as applicable, as proposed to be
filed, contains an untrue statement of a material fact or omits to state any material fact necessary to make the statements therein not misleading or fails to comply with the applicable requirements of the Securities Act in each case with respect to
the information concerning such Holders.

| | (c) | Prepare and file with the SEC such pre-effective amendments and post-effective amendments to each Shelf Registration or Exchange Registration Statement, as the case may
be, as may be necessary to keep such Registration Statement continuously effective for the Effectiveness Period or the Applicable Period, as the case may be; cause the related Prospectus to be supplemented by any Prospectus supplement required by
applicable law, and as so supplemented to be filed pursuant to Rule 424 (or any similar provisions then in force) promulgated under the Securities Act; and comply with the provisions of the Securities Act and the Exchange Act applicable to them with
respect to the disposition of all securities covered by such Registration Statement as so amended or in such Prospectus as so supplemented and with respect to the subsequent resale of any securities being sold by a Participating Broker-Dealer
covered by any such Prospectus.

clause (c) of this Section), as any such Person may reasonably request in writing. The Issuers and the Guarantors hereby consent to the use of the Prospectus by each of the selling Holders of Registrable Notes or each such Participating
Broker-Dealer, as the case may be, and the underwriters or agents, if any, and dealers, if any, in connection with the offering and sale of the Registrable Notes covered by, or the sale by Participating Broker-Dealers of the Exchange Notes pursuant
to, such Prospectus and any amendment or supplement thereto.

Holder of Registrable Notes or Exchange Notes and each Participating Broker-Dealer selling Exchange Notes during the Applicable Period, each Person, if any, who controls each such Holder and Participating Broker-Dealer (within the meaning of
Section 15 of the Securities Act or Section 20(a) of the Exchange Act), from and against any and all losses, claims, damages and liabilities (including, without limitation, reasonable attorneys fees and reasonable expenses incurred
in connection with investigating or defending any of the foregoing as provided in this Section 7) (collectively, Losses), as incurred, directly or indirectly caused by, related to, based upon, arising out of or in connection
with any untrue or alleged untrue statement of a material fact contained in any Registration Statement, Prospectus or form of prospectus, or in any amendment or supplement thereto, or in any preliminary prospectus or free writing prospectus, or
caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, except insofar as such
Losses are caused by such untrue statement or omission or alleged untrue statement or omission based upon any information relating to such Holder or Participating Broker-Dealer furnished to the Issuers or the Guarantors in writing by such Holder or
Participating Broker-Dealer or their counsel expressly for use therein.

| | (b) | Indemnification by Holder. In connection with any Registration Statement, Prospectus or form of prospectus, any amendment or supplement thereto,
or any preliminary prospectus in which a Holder is participating, such Holder shall furnish to the Issuers and the Guarantors in writing such information as the Issuers and the Guarantors reasonably request for use in connection with any
Registration Statement, Prospectus or form of prospectus, any amendment or supplement thereto, or any preliminary prospectus and shall indemnify and hold harmless the Issuers, the Guarantors, their respective directors and officers and each Person,
if any, who controls the Issuers and the Guarantors (within the meaning of Section 15 of the Securities Act and Section 20(a) of the Exchange Act), from and against all Losses arising out of or based upon any untrue or alleged untrue

| | or alleged untrue statement of a material fact or omission or alleged omission of a material fact contained in or omitted from any information so furnished in writing by such Holder to the
Issuers and the Guarantors expressly for use therein. Notwithstanding the foregoing, in no event shall the liability of any selling Holder be greater in amount than such Holders Maximum Contribution Amount (as defined below).
| | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (c) | Conduct of Indemnification Proceedings. If any proceeding shall be brought or asserted against any Person entitled to indemnity hereunder (an
Indemnified Party), such Indemnified Party shall promptly notify the party or parties from which such indemnity is sought (the Indemnifying Party or Indemnifying Parties, as applicable) in
writing; provided, that the failure to so notify the Indemnifying Parties shall not (i) relieve such Indemnifying Party from any obligation or liability unless and only to the extent it is materially prejudiced as a result thereof and
(ii) will not, in any event, relieve the Indemnifying Party from any obligations to any Indemnified Party.
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The Indemnifying Party shall, upon the request of the Indemnified Party, retain counsel reasonably satisfactory to the Indemnified Party
to represent the Indemnified Party and any others the Indemnifying Party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any Indemnified Party shall have
the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party or parties unless: (1) the Indemnifying Party and the Indemnified Party shall have mutually agreed to the retention
of such counsel or (2) the named parties to any such proceeding (including any impleaded parties) include both the Indemnifying Party and the Indemnified Party and representation of both parties by the same counsel would be inappropriate due to
actual or potential differing interests between them. It is understood that the Indemnifying Party shall not, in respect of the legal expenses of any Indemnified Party in connection with any proceeding or related proceedings in the same
jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all such Indemnified Parties and that all such fees and expenses shall be reimbursed as they are incurred. Such firm shall be
designated in writing by a majority of the Holders of the Registrable Notes or Exchange Notes, in the case of parties indemnified pursuant to Section 7(a), by any Issuer or Guarantor, in the case of parties indemnified pursuant to
Section 7(b). The Indemnifying Party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Party
agrees to indemnify the Indemnified Party from and against any loss or liability by reason of such settlement or judgment. No Indemnifying Party shall, without the prior written consent of the Indemnified Party, effect any settlement of any pending
or threatened proceeding in respect of which any Indemnified Party is or could have been a party and indemnity could have been sought hereunder by such Indemnified Party, unless such settlement includes an unconditional release of such Indemnified
Party from all liability on claims that are the subject matter of such proceeding and 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 the indemnification provided for in Section 7(a) or 7(b) is unavailable to an Indemnified Party or is insufficient in
respect of any Losses referred to therein,
| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

---

| | then each Indemnifying Party under such paragraph, in lieu of indemnifying such Indemnified Party thereunder, shall contribute the amount paid or payable by such Indemnified Party as a result of
such Losses (i) in such proportion as is appropriate to reflect the relative benefits received by the Indemnifying Party, on the one hand, and the Indemnified Party, on the other hand or (ii) if the allocation provided by clause 7(d)(i)
above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 7(d)(i) above but also the relative fault of the Indemnifying Party, on the one hand, and of the
Indemnified Party, on the other hand, in connection with the statements or omissions that resulted in such Losses as well as any other relevant equitable considerations. The relative fault of the Indemnifying Party, on the one hand, and the
Indemnified Party, on the other hand, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information
supplied by the Indemnifying Party or by the Indemnified Party, and the parties relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Holders respective obligations to
contribute pursuant to this Section 7 are several in proportion to the respective principal amount of Notes they have purchased hereunder, and not joint.
| | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 7(d) were determined by pro rata allocation or by other method of allocation that does not
take account of the equitable considerations referred to in the immediately preceding paragraph. Notwithstanding the provisions of this Section 7(d), a selling Holder shall not be required to contribute, in the aggregate, any amount in excess
of such Holders Maximum Contribution Amount. A selling Holders Maximum Contribution Amount shall equal the excess of (i) the aggregate proceeds received by such Holder pursuant to the sale of such Registrable
Notes or Exchange Notes over (ii) the aggregate amount of damages that such Holder 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 obligations to contribute pursuant to
this Section 7(d) are several in proportion to the respective principal amount of the Notes held by each Holder hereunder and not joint. The Issuers and Guarantors obligations to contribute pursuant to this Section 7(d) are
joint and several.

The indemnity and contribution agreements contained in this Section 7 are in addition to any
liability that the Indemnifying Parties may have to the Indemnified Parties.



|8. | Rules 144 and 144A
|-- | ------------------

The Issuers and the Guarantors covenant that they shall (a) file the reports required to be filed by it (if so required) under the
Securities Act and the Exchange Act in a timely manner and, if at any time the Issuers or the Guarantors is not required to file such reports, they will, upon the written request of any Holder of Registrable Notes, make publicly available other
information necessary to permit sales pursuant to Rule 144 and 144A and (b) take such further action as any Holder may reasonably request in writing, all to the extent required from time to time to enable such Holder to sell
