 (c) The Issuer shall cause the Shelf Registration Statement and the related
Prospectus and any amendment or supplement thereto, as of the effective date of the Shelf Registration Statement or such amendment or supplement, (i) to comply in all material respects with the applicable requirements of the Act and
(ii) not to contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein (in the case of the Prospectus, in the light of the circumstances
under which they were made) not misleading. 
 (d) Subject to applicable law, the Issuer shall provide written notice to the
Holders of the anticipated effective date of the Shelf Registration Statement at least 15 Business Days prior to such anticipated effective date. Each Holder, in order to be named as a selling securityholder in the Shelf Registration Statement at
the time of its initial effectiveness, shall complete and deliver a Notice and Questionnaire and such other information as the Issuer may reasonably request in writing, if any, to the Issuer at least 10 Business Days prior to the anticipated
effective date of the Shelf Registration Statement as provided in the notice to the Holders. If a Holder does not timely complete and deliver a Notice and Questionnaire or provide the other information the Issuer may reasonably request in writing,
that Holder will not be named as a selling securityholder in the Prospectus forming a part of the Shelf Registration Statement and will not be permitted to sell its Registrable Securities under the Shelf Registration Statement. From and after the
effective date of the Shelf Registration Statement, the Issuer shall use its commercially reasonable efforts, as promptly as is practicable after the date a Notice and Questionnaire is delivered, and in any event within 20 Business Days after such
date, (i) if required by applicable law, to file with the Commission a post-effective amendment to the Shelf Registration Statement or to prepare and, if permitted or required by applicable law, to file a supplement to the Prospectus or an
amendment or supplement to any document incorporated therein by reference or file any other required document so that the Holder delivering such Notice and Questionnaire is named as a selling securityholder in the Shelf Registration Statement and
the related Prospectus, and so that such Holder is permitted to deliver such Prospectus to purchasers of the Registrable Securities in accordance with applicable law (provided that the Issuer shall not be required to file more than one
supplement or post-effective amendment in any 30-day period in accordance with this Section 2(d)(i)) and, if the Issuer shall file a post-effective amendment to the Shelf Registration Statement, use its
commercially reasonable efforts to cause such post-effective amendment to be declared effective under the Act as promptly as is practicable; (ii) provide such Holder, upon request, copies of any documents filed pursuant to Section 2(d)(i)
hereof; and (iii) notify such Holder as promptly as practicable after the effectiveness under the Act of any post-effective amendment filed pursuant to Section 2(d)(i) hereof; provided that if such Notice and Questionnaire is
delivered during a Deferral Period, the Issuer shall so inform the Holder delivering such Notice and Questionnaire and shall take the actions set forth in clauses (i), (ii) and (iii) above upon expiration of the Deferral Period in accordance
with Section 3(i) hereof. Notwithstanding anything contained herein to the contrary, the Issuer shall be under no obligation to name any Holder that is not a Notice Holder as a selling securityholder in the Shelf Registration Statement or
related Prospectus; provided, however, that any Holder that becomes a Notice Holder pursuant to the provisions of this Section 2(d) (whether or not such Holder was a Notice Holder at the effective date of the Shelf Registration
Statement) shall be named as a selling securityholder in the Shelf Registration Statement or related Prospectus in accordance with the requirements of this Section 2(d). 

  
 5 













 (e) If at any time the Notes, pursuant to Section 14.07 of the
Indenture, are convertible for securities of the Issuer other than the Common Stock, the Issuer agrees to cause such securities to be included in the Shelf Registration Statement or a replacement shelf registration statement no later than the date
on which the Notes become convertible for such securities. 
 3. Registration Procedures. The following provisions shall apply in
connection with the Shelf Registration Statement. 
 (a) The Issuer shall: 

(i) furnish to the Representatives and the Notice Holders, not less than five Business Days prior to the filing thereof with
the Commission, a copy of the Shelf Registration Statement and each amendment thereto and each amendment or supplement, if any, to the Prospectus (other than amendments and supplements that do nothing more than name Notice Holders and provide
information with respect thereto and other than filings by the Issuer under the Exchange Act) and shall use its commercially reasonable efforts to reflect in each such document, when so filed with the Commission, such comments as any Representative
reasonably proposes within three Business Days of the delivery of such copies to the Representatives; and 
 (ii) include
information regarding the Notice Holders and the methods of distribution they have elected for their Registrable Securities provided to the Issuer in Notices and Questionnaires as necessary to permit such distribution by the methods specified
therein. 
 (b) The Issuer shall ensure that: 

(i) the Shelf Registration Statement and any amendment thereto, and any Prospectus and any amendment or supplement thereto,
comply in all material respects with the Act; and 
 (ii) the Shelf Registration Statement and any amendment thereto do not,
when each becomes effective, 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. 

(c) The Issuer shall advise the Representatives and the Notice Holders and confirm such advice in writing, if requested (which
notice pursuant to clauses (ii)-(v) below shall be accompanied by an instruction to suspend the use of the Prospectus until the Issuer shall have remedied the basis for such suspension): 

(i) when the Shelf Registration Statement and any amendment thereto have been filed with the Commission and when the Shelf
Registration Statement or any post-effective amendment thereto has become effective; 

  
 6 













 (ii) of any request by the Commission for any post-effective amendment or
supplement to the Shelf Registration Statement or the related Prospectus or for additional information; 
 (iii) of the
issuance by the Commission of any stop order suspending the effectiveness of the Shelf Registration Statement or the initiation or threatening of any proceeding for that purpose; 

(iv) of the receipt by the Issuer of any notification with respect to the suspension of the qualification of the Notes or the
Common Stock included therein for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and 

(v) of the happening of any event that requires any change in the Shelf Registration Statement or the related Prospectus so
that, as of such date, they (A) do not contain any untrue statement of a material fact and (B) do not omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of the Prospectus,
in the light of the circumstances under which they were made) not misleading. 
 (d) Subject to Section 3(i) below, the
Issuer shall use its commercially reasonable efforts to prevent the issuance of any order suspending the effectiveness of the Shelf Registration Statement or the qualification of the securities therein for sale in any jurisdiction and, if issued, to
obtain as soon as possible the withdrawal thereof. 
 (e) Upon request, the Issuer shall furnish, in electronic or physical
form, to each Notice Holder, without charge, at least one copy of the Shelf Registration Statement and any post-effective amendment thereto, including all material incorporated therein by reference, and, if a Notice Holder so requests in writing,
all exhibits thereto (including exhibits incorporated by reference therein). 
 (f) During the Shelf Registration Period, the
Issuer shall promptly deliver to each Initial Purchaser and each Notice Holder, without charge, as many copies of the Prospectus (including the preliminary Prospectus, if any) included in the Shelf Registration Statement and any amendment or
supplement thereto as any such person may reasonably request. Subject to the restrictions set forth in this Agreement, the Issuer consents to the use of the Prospectus or any amendment or supplement thereto by each of the foregoing in connection
with the offering and sale of the Registrable Securities. 
 (g) Prior to any offering of Registrable Securities pursuant to
the Shelf Registration Statement, the Issuer shall arrange for the qualification of the Registrable Securities for sale under the laws of such U.S. jurisdictions as any Notice Holder shall reasonably request and shall maintain such qualification in
effect so long as required; provided that in no event shall the Issuer be obligated by this Agreement to qualify to do business or as a dealer of securities in any jurisdiction where it is not then so qualified or to take any action that
would subject it to taxation or service of process in suits in any jurisdiction where it is not then so subject. 

  
 7 













 (h) Upon the occurrence of any event contemplated by subsections (c)(ii)
through (v) above, the Issuer shall promptly (or within the time period provided for by Section 3(i) hereof, if applicable) prepare a post-effective amendment to the Shelf Registration Statement or an amendment or supplement to the
Prospectus or file any other required document so that, as thereafter delivered to subsequent purchasers of the securities included therein, the Prospectus will not include an untrue statement of a material fact or omit to state any material fact
required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. 

(i) Upon the occurrence or existence of any pending corporate development, public filings with the Commission or any other
material event that, in the reasonable judgment of the Issuer, makes it appropriate to suspend the availability of the Shelf Registration Statement and the related Prospectus, the Issuer shall give notice (without notice of the nature or details of
such events) to the Notice Holders that the availability of the Shelf Registration Statement is suspended and, upon receipt of any such notice, each Notice Holder agrees: (i) not to sell any Registrable Securities pursuant to the Shelf
Registration Statement until such Notice Holder receives copies of the supplemented or amended Prospectus provided for in Section 3(h) hereof, or until it is advised in writing by the Issuer that the Prospectus may be used, and has received
copies of any additional or supplemental filings that are incorporated or deemed incorporated by reference in such Prospectus; and (ii) to hold such notice strictly confidential. Except in the case of a suspension of the availability of the
Shelf Registration Statement and the related Prospectus solely as the result of the filing of a post-effective amendment or supplement to the Prospectus to add additional selling securityholders therein, the period during which the availability of
the Shelf Registration Statement and any Prospectus is suspended (the “Deferral Period”) shall not exceed 30 days in any calendar quarter or 60 days in any calendar year; provided that if the suspension relates to a proposed
or pending material business transaction, the disclosure of which the board of directors of the Issuer (or an authorized committee thereof) determines in good faith would be reasonably likely to impede the ability to consummate such transaction or
would otherwise be detrimental to the Issuer, the Issuer may extend the Deferral Period from 30 days to 45 days in any calendar quarter and from 60 days to 90 days in any calendar year. 

(j) The Issuer shall comply with all applicable rules and regulations of the Commission and shall make generally available to
its securityholders an earnings statement (which need not be audited) satisfying the provisions of Section 11(a) of the Act as soon as practicable after the effective date of the Shelf Registration Statement and in any event no later than 45
days after the end of the 12-month period (or 90 days, if such period is a fiscal year) beginning with the first month of the Issuer’s first fiscal quarter commencing after the effective date of the Shelf
Registration Statement. 
 (k) The Issuer may require each Holder of Registrable Securities to be sold pursuant to the Shelf
Registration Statement to furnish to the Issuer such information regarding the Holder and the distribution of such Registrable Securities as the Issuer may from time to time reasonably require for inclusion in the Shelf Registration Statement. The
Issuer may exclude from the Shelf Registration Statement the Registrable Securities of any Holder that unreasonably fails to furnish such information within 10 Business Days after receiving such request. 

  
 8 













 (l) Subject to Section 6 hereof, the Issuer shall enter into customary
agreements (including, in the event of an underwritten offering conducted pursuant to Section 6 hereof, an underwriting agreement in customary form, customary legal opinions, customary comfort letters and other customary documents and
certifications by the Issuer and by the selling securityholders) and take all other necessary actions in order to expedite or facilitate the registration or the disposition of the Registrable Securities, and in connection therewith, if an
underwriting agreement is entered into, cause the same to contain customary indemnification provisions and procedures. 
 (m)
Subject to Section 6 hereof, in the event that any Broker-Dealer shall underwrite any Notes or Common Stock or participate as a member of an underwriting syndicate or selling group or “participate in an offering” (within the meaning
of the FINRA Rules) thereof, whether as a Holder of such Notes or Common Stock or as an underwriter, a placement or sales agent or a broker or dealer in respect thereof, or otherwise, the Issuer shall, upon the reasonable request of such
Broker-Dealer, comply with any such reasonable request of such Broker-Dealer in complying with the applicable FINRA Rules. 

(n) The Issuer shall use its commercially reasonable efforts to take all other steps necessary to effect the registration of
the Notes and Common Stock covered by the Shelf Registration Statement. 
 4. Registration Expenses. The Issuer shall bear all
expenses incurred in connection with the performance of their obligations under Sections 2 and 3 hereof, and the Holders and the Representatives shall bear all expenses incurred by them in connection with any sale of Registrable Securities pursuant
to the Shelf Registration Statement. 
 5. Indemnification and Contribution. 

(a) To the extent permitted by applicable law, the Issuer agrees to indemnify and hold harmless each Holder covered by the
Shelf Registration Statement and the directors, officers, employees, Affiliates and agents of each such Holder and each person who controls any such Holder within the meaning of either the Act or the Exchange Act against any and all losses, claims,
damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Shelf Registration Statement as originally filed or in any amendment thereof, or in any
preliminary Prospectus or the Prospectus, or in any amendment thereof 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 (in the case of any preliminary Prospectus or the Prospectus, in the light of the circumstances under which they were made) not misleading, and agrees to reimburse 

  
 9 













 
each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by it in connection with investigating or defending any such loss, claim, damage, liability or
action; provided, however, that the foregoing indemnity shall not apply to amounts paid in settlement of any such loss if such settlement is effected without the consent of the Issuer (which consent shall not be unreasonably withheld
or delayed), nor shall the Issuer be liable (x) in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission
made therein in reliance upon and in conformity with written information furnished to the Issuer by or on behalf of the party claiming indemnification specifically for inclusion therein or (y) to any Holder from whom the person asserting any
such losses, claims, damages or liabilities purchased the Notes or Common Stock concerned, to the extent that a Prospectus relating to such Notes or Common Stock was required under the Act to be delivered (including through satisfaction of the
conditions of Rule 172 under the Act) by such Holder in connection with such purchase and any such loss, claim, damage or liability of such Holder results from the fact that there was not conveyed to such person, at or prior to the time of the sale
of such Notes or Common Stock to such person, an amended or supplemented prospectus or (if available) a free writing prospectus of the Issuer, in each case, correcting such untrue statement or omission or alleged untrue statement or omission if the
Issuer had furnished copies thereof to such Holder prior to the time of the sale of such Notes or Common Stock to such person. This indemnity agreement shall be in addition to any liability that the Issuer may otherwise have to the indemnified
party. 
 (b) Each Holder of securities covered by the Shelf Registration Statement (including each Initial Purchaser that is
a Holder, in such capacity) severally and not jointly agrees to indemnify and hold harmless the Issuer, each of the Issuer’s directors, each of the Issuer’s officers who signs the Shelf Registration Statement and each person who controls
the Issuer within the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnity from the Issuer to each such Holder, but only with reference to written information relating to such Holder furnished to the Issuer by
or on behalf of such Holder specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement shall be acknowledged by each Notice Holder that is not an Initial Purchaser in such Notice Holder’s Notice
and Questionnaire and shall be in addition to any liability that any such Notice Holder may otherwise have to the Issuer. 

(c) Promptly after receipt by an indemnified party under this Section 5 of notice of the commencement of any action, such
indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 5, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party
(i) will not relieve it from liability under Section 5(a) or Section 5(b) hereof unless and to the extent it has been materially prejudiced through the forfeiture by the indemnifying party of substantial rights and defenses; and
(ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in Section 5(a) or Section 5(b) hereof. If any action shall be brought
against an indemnified party and it shall have notified the indemnifying party thereof, the indemnifying party shall be entitled to 

  
 10 













 
appoint counsel (including local counsel) of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which
indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel, other than local counsel if not appointed by the indemnifying party, retained by the indemnified
party or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel (including local
counsel) to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate
counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest; (ii) the actual or potential defendants in, or targets of, any such action
include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties that are different from or additional to those
available to the indemnifying party; (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the initiation of
such action; or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. It is understood and agreed that the indemnifying party shall not, in connection with any
proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate law firm (in addition to any local counsel) for all indemnified persons. An indemnifying party will not, without the prior
written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought
hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of
such claim, action, suit or proceeding and does not include an admission of fault, culpability or a failure to act, by or on behalf of such indemnified party. 

(d) In the event that the indemnity provided in Section 5(a) or Section 5(b) is unavailable to or insufficient to
hold harmless an indemnified party for any reason, then each applicable indemnifying party shall have a joint and several obligation to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably
incurred in connection with investigating or defending any loss, claim, liability, damage or action) (collectively “Losses”) to which such indemnified party may be subject in such proportion as is appropriate to reflect the relative
benefits received by such indemnifying party, on the one hand, and such indemnified party, on the other hand, from the Initial Placement and the Shelf Registration Statement which resulted in such Losses; provided, however, that in no
case shall any Initial Purchaser be responsible, in the aggregate, for any amount in excess of the purchase discount or commission applicable to the Notes, as set forth in the Final Memorandum, nor shall any underwriter be responsible for any amount
in excess of the underwriting discount or commission applicable to the securities purchased by such underwriter under the Shelf Registration 

  
 11 













 
Statement which resulted in such Losses. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the indemnifying party and the indemnified party shall
contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of such indemnifying party, on the one hand, and such indemnified party, on the other hand, in connection with the statements or
omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Issuer shall be deemed to be equal to the total net proceeds from the Initial Placement (before deducting expenses) as set forth
in the Final Memorandum. Benefits received by the Initial Purchasers shall be deemed to be equal to the total purchase discounts and commissions as set forth in the Final Memorandum, and benefits received by any other Holders shall be deemed to be
equal to the value of receiving Notes or shares of Common Stock registered under the Act. Benefits received by any underwriter shall be deemed to be equal to the total underwriting discounts and commissions, as set forth on the cover page of the
Prospectus forming a part of the Shelf Registration Statement which resulted in such Losses. Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or omission or
alleged omission to state a material fact relates to information provided by the indemnifying party, on the one hand, or by the indemnified party, on the other hand, the intent of the parties and their relative knowledge, access to information and
opportunity to correct or prevent such untrue statement or omission. The parties agree that it would not be just and equitable if contribution were determined by pro rata allocation (even if the Holders were treated as one entity for such purpose)
or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this Section 5(d), no person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 5, each person who controls a Holder within the meaning of either the Act or
the Exchange Act and each director, officer, employee and agent of such Holder shall have the same rights to contribution as such Holder, and each person who controls the Issuer within the meaning of either the Act or the Exchange Act, each officer
of the Issuer who shall have signed the Shelf Registration Statement and each director of the Issuer shall have the same rights to contribution as the Issuer, subject in each case to the applicable terms and conditions of this Section 5(d).

 (e) The provisions of this Section 5 shall remain in full force and effect, regardless of any investigation made by
or on behalf of any Holder or the Issuer or any of the indemnified persons referred to in this Section 5, and shall survive the sale by a Holder of securities covered by the Shelf Registration Statement. 

6. Underwritten Registrations. 

(a) In no event will the method of distribution of Registrable Securities take the form of an underwritten offering without the
prior written consent of the Issuer. Consent may be conditioned on waivers of any of the obligations in Section 3, Section 4 or Section 5 hereof. 

  
 12 













 (b) If any Registrable Securities are to be sold in an underwritten
offering, the underwriters shall be selected by the Issuer. 
 (c) No person may participate in any underwritten offering
pursuant to the Shelf Registration Statement unless such person: (i) agrees to sell such person’s Registrable Securities on the basis reasonably provided in any underwriting arrangements approved by the Issuer; 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. 

7. Registration Defaults. If (x) any of the following events shall occur as a result of the Issuer’s failure to satisfy its
obligations hereunder (each of the events set forth in clauses (a) through (d) below, a “Registration Default”) and (y) (I) the Issuer has failed to file all reports and other materials required to be filed by
Section 13 or 15(d) of the Exchange Act, as applicable, during the preceding 12 months (or for such shorter period that the Issuer was required to file such reports and materials), after giving effect to all applicable grace periods thereunder
and other than reports on Form 8-K, or (II) the Notes are not otherwise freely tradable pursuant to Rule 144 under the Act by “Holders” (as defined in the Indenture) other than the Issuer’s
Affiliates or “Holders” (as defined in the Indenture) that were the Issuer’s Affiliates at any time during the immediately preceding three months (as a result of restrictions pursuant to U.S. securities laws or the terms of the
Indenture or the Notes) (each of clause (I) and clause (II), a “Rule 144 Unavailability Event”), then the Issuer shall pay additional interest on the Notes (“Registration Default Additional Interest”) to
the “Holders” (as defined in the Indenture) of the Notes as follows: 
 (a) if the Shelf Registration Statement has
not been filed with the Commission and become or declared effective, as the case may be, on or prior to the 375th day after the Closing Date, then commencing on the 376th day after the Closing Date, Registration Default Additional Interest shall
accrue on the aggregate outstanding principal amount of the Notes at a rate of 0.50% per annum; or 
 (b) if the Shelf
Registration Statement has been declared or becomes effective but ceases to be effective or usable for the offer and sale of the Registrable Securities, other than (i) in connection with a Deferral Period or (ii) as a result of the filing
of a post-effective amendment or supplement to the Prospectus to make changes to the information regarding selling securityholders or the plan of distribution provided for therein, at any time during the Shelf Registration Period and the Issuer does
not cure the lapse of effectiveness or usability within 10 Business Days (or within 10 Business Days following the expiration of such Deferral Period or period permitted pursuant to Section 2(d)), then Registration Default Additional Interest
shall accrue on the aggregate outstanding principal amount of the Notes at a rate of 0.50% per annum; or 
 (c) if the Issuer
through its omission fails to name a Holder as a selling securityholder and such Holder had complied timely with its obligations hereunder in a manner to entitle such Holder to be so named in (i) the Shelf Registration Statement at the time it
first became effective or (ii) any Prospectus at the later of time of filing thereof or the time the Shelf Registration Statement of which the Prospectus forms a part 

  
 13 













 
becomes effective, then Registration Default Additional Interest shall accrue, on the aggregate outstanding principal amount of the Notes held by such Holder, at a rate of 0.50% per annum from
and including the day following the effective date of such Shelf Registration Statement or the time of filing of such Prospectus, as the case may be, which Registration Default Additional Interest shall be payable separately to such Holder at the
account specified in writing by such Holder to the Issuer; or 
 (d) if the aggregate duration of Deferral Periods in any
period exceeds the number of days permitted in respect of such period pursuant to Section 3(i) hereof, then commencing on the day the aggregate duration of Deferral Periods in any period exceeds the number of days permitted in respect of such
period, Registration Default Additional Interest shall accrue on the aggregate outstanding principal amount of the Notes at a rate of 0.50% per annum; 

provided, however, that (1) upon the filing and effectiveness (whether upon such filing or otherwise) of the Shelf Registration Statement
(in the case of paragraph (a) above), (2) upon such time as the Shelf Registration Statement which had ceased to remain effective or usable for resales again becomes effective and usable for resales (in the case of paragraph (b) above),
(3) upon the time such Holder is permitted to sell its Registrable Securities pursuant to any Shelf Registration Statement and Prospectus in accordance with applicable law (in the case of paragraph (c) above), (4) upon the termination of the
Deferral Period that caused the limit on the aggregate duration of Deferral Periods in a period set forth in Section 3(i) to be exceeded (in the case of paragraph (d) above), (5) in any case, notwithstanding the preceding clauses
(1) through (4), upon the earliest of the three dates provided in clauses (i), (ii) and (iii) of Section 2(b), or (6) upon the cessation of all Rule 144 Unavailability Events, Registration Default Additional Interest shall
immediately cease to accrue. 
 Any amounts of Registration Default Additional Interest due pursuant to this Section 7 will be payable
in arrears on each Interest Payment Date (as defined in the Indenture) following accrual in the same manner as regular interest on the Notes as described in the Indenture and shall be in addition to any remedy relating to the failure to comply with
the Issuer’s obligations under Section 4.06(b) of the Indenture. If any Note ceases to be outstanding during any period for which Registration Default Additional Interest is accruing (other than as a result of the Holder exercising its
conversion rights pursuant to Article 14 of the Indenture), the Issuer will prorate the Registration Default Additional Interest payable with respect to such Note. 

The Registration Default Additional Interest rate on the Notes shall not exceed in the aggregate 0.50% per annum and shall not be payable under
more than one clause above for any given period of time. Other than the Issuer’s obligation to pay Registration Default Additional Interest in accordance with this Section 7, the Issuer will not have any liability for damages with respect
to a Registration Default. 

  
 14 













 Notwithstanding any provision in this Agreement, (x) in no event shall Registration
Default Additional Interest accrue or be payable to holders of Common Stock issued upon conversion of Notes and (y) if a Registration Default occurs after a Holder has converted its Notes for Common Stock, such Holder shall not be entitled to
any Registration Default Additional Interest with respect to such Common Stock. 
 8. No Inconsistent Agreements. The Issuer has not
entered into, and agrees not to enter into, any agreement with respect to its securities that conflicts with the registration rights granted to the Holders herein. 

9. Rule 144A and Rule 144. So long as any Registrable Securities remain outstanding, the Issuer shall use its commercially reasonable
efforts to file the reports required to be filed by it under Rule 144A(d)(4) under the Act and the Exchange Act in a timely manner and, if at any time the Issuer is not required to file such reports, it will, upon the written request of any Holder
of Registrable Securities, make publicly available other information so long as necessary to permit sales of such Holder’s Registrable Securities pursuant to Rules 144 and 144A of the Act. Upon the written request of any Holder of Registrable
Securities, the Issuer shall deliver to such Holder a written statement as to whether it has complied with such requirements. Notwithstanding the foregoing, nothing in this Section 9 shall be deemed to require the Issuer to register any of its
securities pursuant to the Exchange Act. 
 10. [Reserved.]

14. Successors. This Agreement shall inure to the benefit of and be binding upon the parties hereto, their respective successors and
