Questionnaire is first mailed to such Holders to return a completed and signed Notice and Questionnaire to the Company.

Holder as a selling securityholder in the Shelf Registration Statement or to enable such Holder to use the Prospectus for resales of Registrable Securities until such Holder has returned a completed and signed Notice and Questionnaire to the

Questionnaire, the Company shall as promptly as practicable thereafter, and in any event upon the later of (A) fifteen (15) days after the date of
receipt of such Notice and Questionnaire or (B) if the use of the Prospectus has been suspended by the Company under Section 2(c) hereof at the time of receipt of the Notice and Questionnaire, ten (10) days after the expiration of the
period during which the use of the Prospectus is suspended, (1) if required by applicable law, file with the Commission a post-effective amendment to the Shelf Registration Statement or prepare and, if required by applicable law, file a
supplement to the Prospectus 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 in such a manner as to
permit such Holder to deliver such Prospectus to purchasers of the Registrable Securities in accordance with applicable law and, (2) if the Company shall file a post-effective amendment to the Shelf Registration Statement, use its reasonable
efforts to cause such post-effective amendment to be declared effective under the Securities Act as promptly as is practicable, but in any event by the date that is forty-five (45) days after the date such post-effective amendment is required
by this clause to be filed. Notwithstanding the foregoing, the Company shall not be required to file more than one post-effective amendment to the Shelf Registration Statement during any thirty (30) day period.

 (b) The Company shall (i) furnish to each
Electing Holder, prior to the Effective Time, a copy of the Shelf Registration Statement initially filed with the Commission, and shall furnish to such Holders, prior to the filing thereof with the Commission, copies of each amendment thereto and
each amendment or supplement, if any, to the Prospectus included therein (other than supplements that do nothing more than name Holders and provide information with respect thereto), and shall use its reasonable efforts to reflect in each such
document, at the Effective Time or when so filed with the Commission, as the case may be, such comments as such Holders and their respective counsel reasonably may propose and which the Company receives at least 5 days prior to the filing of such
document, and (ii) name the Electing Holders as selling securityholders in the Shelf Registration Statement. 
 (c) The
Company shall promptly take such action as may be necessary so that (i) the Shelf Registration Statement and any amendment thereto and the Prospectus and any amendment or supplement thereto (and each report or other document incorporated
therein by reference in each case) complies in all material respects with the Securities Act, the Exchange Act and the Rules and Regulations, (ii) the Shelf Registration Statement and any amendment thereto does not, when it 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 and (iii) the Prospectus and any amendment or supplement thereto, does not
at any time during the Registration Period include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not
misleading.

 (d) The Company shall promptly notify each Electing Holder in writing: 
 (i) when a Shelf Registration Statement and any amendment thereto has been filed with the Commission and when a Shelf Registration
Statement or any post-effective amendment thereto has become effective; 
 (ii) of any request by the Commission after the
Shelf Registration Statement has become effective for amendments or supplements to the Shelf Registration Statement or the 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 of any proceedings for such purpose; 
 (iv) if the Company receives any notification with respect to the
suspension of the qualification of the securities included in the Shelf Registration Statement for sale in any jurisdiction or the initiation of any proceeding for such purpose; and 
 (v) of the happening of any event or the existence of any state of facts that requires the making of any changes in the Shelf Registration
Statement or the Prospectus so that, as of such date, the Shelf Registration Statement and the Prospectus do not contain an untrue statement of a material fact and 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 light of the circumstances under which they were made) not misleading. 
 A
notice pursuant to clauses (ii) through (v) above may be accompanied by an instruction to suspend the use of the Prospectus until the requisite changes to the Prospectus have been made or such other action is taken to remedy the fact or
event that led to the suspension of the use of the Prospectus. 
 (e) The Company shall use its reasonable efforts:
(i) to prevent the issuance of any order suspending the effectiveness of the Shelf Registration Statement; (ii) if issued, to obtain the withdrawal of any such order at the earliest possible time; and (iii) to provide prompt notice to
each Electing Holder of the withdrawal of such order. 
 (f) The Company shall furnish to each Electing Holder, without
charge, at least one copy of the Shelf Registration Statement and all post-effective amendments thereto, including financial statements and schedules, and, if such Electing Holder so requests in writing, all reports, other documents and exhibits
that are filed with or incorporated by reference in the Shelf Registration Statement. 
 (g) The Company shall, during the
Registration Period, deliver to each Electing Holder, without charge, as many copies of the Prospectus (including each preliminary prospectus) and any amendment or supplement thereto as such Electing Holder may reasonably request in connection with
the offering and sale of the Registrable Securities. The Company consents (except during the periods specified in Section 2(c) above or during the continuance of any event described in clauses (ii) through (v) of Section 3(d)
above) to the use of the Prospectus and any amendment or supplement thereto by each of the Electing Holders in connection with the offering and sale of the Registrable Securities covered by the Prospectus and any amendment or supplement thereto
during the Registration Period. 
  

 -7- 








 (h) The Company shall: (i) prior to any offering of Registrable Securities pursuant
to the Shelf Registration Statement, register or qualify or cooperate with the Electing Holders and their respective counsel in connection with the registration or qualification of such Registrable Securities for offer and sale under the securities
or “blue sky” laws of such jurisdictions within the United States as any Electing Holder may reasonably request; (ii) keep such registrations or qualifications in effect and comply with such laws so as to permit the continuance of
offers and sales in such jurisdictions for so long as may be necessary to enable any Electing Holder or underwriter, if any, to complete its distribution of Registrable Securities pursuant to the Shelf Registration Statement; and (iii) take any
and all other actions necessary or advisable to enable the disposition in such jurisdictions of such Registrable Securities; provided, however, that in no event shall the Company be obligated to (A) qualify as a foreign
corporation or as a dealer in securities in any jurisdiction where it would not otherwise be required to so qualify but for this Section 3(h) or (B) file any general consent to service of process in any jurisdiction where it is not then so
subject. 
 (i) Except with respect to Registrable Securities in book-entry only form, the Company shall cooperate with the
Electing Holders to facilitate the timely preparation and delivery of certificates representing Registrable Securities to be sold pursuant to the Shelf Registration Statement, which shall be free of any restrictive legends and in such denominations
and registered in such names as the Electing Holders may request a reasonable period of time prior to sales of such Registrable Securities pursuant to the Shelf Registration Statement. 
 (j) Upon the occurrence of any fact or event contemplated by clauses (ii) through (v) of Section 3(d) above during the
Registration Period, the Company shall promptly prepare a post-effective amendment to the Shelf Registration Statement or an amendment or supplement to the related Prospectus or file any other required document or take such other action so that,
(A) with respect to clauses (ii) through (iv) of Section 3(d), the fact or event which has led to the suspension of the use of the Prospectus is remedied, and (B) with respect to clause (v) of Section 3(d), as
thereafter delivered to purchasers of the Registrable Securities included therein, the Prospectus will not include an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of
the circumstances under which they were made, not misleading. If the Company provides notice to the Electing Holders of the occurrence of any fact or event contemplated by clauses (ii) through (v) of Section 3(d) above along with an
instruction to suspend the use of the Prospectus, the Electing Holder shall suspend the use of the Prospectus until the requisite changes to the Prospectus have been made or such other action is taken to remedy the fact or event that led to the
suspension of the use of the Prospectus. 
 (k) Not later than the Effective Time, the Company shall provide a CUSIP number
for the Registrable Securities that are debt securities. 
 (l) The Company will comply with all Rules and Regulations to the
extent and so long as they are applicable to the Shelf Registration Statement and will make generally available to its securityholders (or otherwise provide in accordance with Section 11(a) of the Securities Act) an earnings statement
satisfying the provisions of Section 11(a) of the Securities Act, no later than 45 days after the end of a 12-month period (or 90 days, if such period is a fiscal year) beginning with the first month of the Company’s first fiscal

 -8- 








 
after the effective date of the Shelf Registration Statement, which statement shall cover such 12-month period. For purposes of this paragraph, the term
“effective date” with respect to the Shelf Registration Statement shall have the meaning assigned to it in paragraph (c) of Rule 158 (or any successor provision thereto) under the Securities Act. 
 (m) Not later than the Effective Time, the Company shall cause the Indenture to be qualified under the Trust Indenture Act. In connection
with such qualification, the Company shall cooperate with the Trustee and the Holders (as defined in the Indenture) to effect such changes to the Indenture as may be required for such Indenture to be so qualified in accordance with the terms of the
Trust Indenture Act; and the Company shall execute, and shall use its best efforts to cause the Trustee to execute, all documents that may be required to effect such changes and all other forms and documents required to be filed with the Commission
to enable such Indenture to be so qualified in a timely manner. In the event that any such amendment or modification referred to in this Section 3(m) involves 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. 
 (n) The Company shall enter into such customary
agreements (including an underwriting agreement in customary form in the event of an underwritten offering in accordance with Section 6 below) and take all other appropriate action in order to expedite and facilitate the registration and

employees to supply all information reasonably requested by such Electing Holders or any such underwriter, attorney, accountant or agent in connection with the Shelf Registration Statement, in each case, as is customary for similar due diligence
examinations in connection with the sale of securities of a public company; provided that such inspection and information gathering shall, to the greatest extent possible, be coordinated by one counsel designated by and on behalf of the
Electing Holders and other parties; provided, further, that such persons shall, at the Company’s request, first agree in writing with the Company that any information that is reasonably and in good faith designated by the Company in
writing as confidential at the time of delivery of such information shall be kept confidential by such persons and shall be used solely for the purpose of exercising rights under this Agreement; and provided, further, that the Company shall
not be required to disclose any information subject to the attorney-client or attorney work product privilege if and to the extent such disclosure would constitute a waiver of such privilege.

placement or sales agent or a broker or dealer in respect thereof, or otherwise, the Company shall assist such broker-dealer in complying with the requirements of the NASD Rules, including, without limitation, by (i) if the NASD Rules shall so
require, engaging a “qualified independent underwriter” (as defined in Rule 2720 of the NASD Rules (or any successor provision thereto)) to participate in the preparation of the registration statement relating to such Registrable
Securities, to exercise usual standards of due diligence in respect thereto and to recommend the public offering price of such Registrable Securities, (B) indemnifying any such qualified independent underwriter to the extent of the

 (s) The Company may require each
Electing Holder to furnish to the Company such information regarding the Electing Holder and the distribution of the Registrable Securities as the Company may from time to time reasonably request for inclusion in the Shelf Registration Statement,
and the Company may exclude from such registration the Registrable Securities of any Electing Holder that unreasonably fails to furnish such information within a reasonable time after receiving such request. 
 4. Registration Expenses. The Company will bear all Registration Expenses incurred in connection with the performance of its obligations
hereunder. The Company will also bear or reimburse the Electing Holders for the reasonable fees and disbursements of one counsel for the Holders (to the extent and as determined by a majority of the Electing Holders) in connection with the Shelf
Registration Statement. Each Electing Holder shall pay all underwriting discounts and commissions and transfer taxes, if any, and, subject to the preceding sentence, the expenses of its own counsel, relating to the sale or disposition of such
Electing Holder’s Registrable Securities pursuant to the Shelf Registration Statement. 
 5. Indemnification and Contribution.

 (a) Indemnification by the Company. The Company agrees to indemnify and hold harmless each Electing Holder and
each person, if any, who controls any Electing Holder within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without
limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Shelf Registration
Statement or any amendment thereof, any preliminary prospectus or the Prospectus (as amended or supplemented if the Company shall have furnished any amendments or supplements thereto), or caused by any omission or alleged omission to state therein a
material fact required to be stated therein or 

  

 -10- 








 
necessary to make the statements therein not misleading, except insofar as such losses, claims, damages or liabilities are caused by any such untrue
statement or omission or alleged untrue statement or omission based upon information relating to any Electing Holder furnished to the Company in writing by such Electing Holder expressly for use in the Shelf Registration Statement, any amendment
thereof, any preliminary prospectus, the Prospectus or any amendments or supplements thereto. In connection with any underwritten offering permitted hereunder, the Company will also indemnify the underwriters, their officers and directors and each
person who controls such underwriters (within the meaning of the Securities Act and the Exchange Act) to the same extent as provided above with respect to the indemnification of the Electing Holders, if requested by such Electing Holders.

 (b) Indemnification by the Electing Holders. Each Electing Holder agrees, severally and not jointly, to
indemnify and hold harmless the Company, the directors of the Company, the officers of the Company who sign the Shelf Registration Statement and each person, if any, who controls the Company within the meaning of either Section 15 of the
Securities Act or Section 20 of the Exchange Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating
any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Shelf Registration Statement or any amendment thereof, any preliminary prospectus or the Prospectus (as amended or supplemented
if the Company shall have furnished any amendments or supplements thereto), 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 not misleading, but
only with reference to information relating to such Electing Holder furnished to the Company in writing by such Electing Holder expressly for use in the Shelf Registration Statement, any amendment thereof, any preliminary prospectus, the Prospectus
or any amendments or supplements thereto. In no event shall the liability of any Electing Holder hereunder be greater in amount than the dollar amount of the proceeds received by such Electing Holder from the sale of such Electing Holder’s
Registrable Securities (after deducting any fees, discounts and commissions applicable thereto) pursuant to the Shelf Registration Statement. 
 (c) Indemnification Procedures. In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to this
Section 5, such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party, upon request of the
indemnified party, shall 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 unless (i) the
indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) 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 

  

 -11- 








 
jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all indemnified parties, and that all
such fees and expenses shall be reimbursed as they are incurred. In the case of any such separate firm for the Electing Holders and such control persons of any Electing Holders, such firm shall be designated in writing by the Electing Holders
holding a majority of the Registrable Securities covered by the Shelf Registration Statement with the approval of the Company, which approval shall not be unreasonably withheld. In the case of any such separate firm for the Company and such
directors, officers and control persons of the Company, such firm shall be designated in writing by the Company. 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. Notwithstanding the foregoing
sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the indemnifying party
agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and
(ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. 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. 
 (d)
Contribution Agreement. To the extent the indemnification provided for in paragraph (a) or paragraph (b) of this Section 5 is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or
liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses,
claims, damages or liabilities in such proportion as is appropriate to reflect the relative fault of the indemnifying party or parties on the one hand and of the indemnified party or parties on the other hand in connection with the statements or
omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative fault of the Company on the one hand and the Electing Holders 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 Company or by the Electing Holders and the
parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Electing Holders’ respective obligations to contribute pursuant to this Section 5(d) are several in
proportion to the respective principal amount of Registrable Securities of each such Electing Holder that were registered pursuant to the Shelf Registration Statement, and not joint. 
 (e) Contribution Amounts. The Company and the Electing Holders agree that it would not be just or equitable if contribution
pursuant to Section 5(d) were determined by pro rata allocation (even if the Electing Holders were treated as one entity for such purpose) or by 

  

 -12- 








 
any other method of allocation that does not take account of the equitable considerations referred to in Section 5(d). The amount paid or payable by an
indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 5(d) shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified
party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 5, no Electing Holder shall be required to contribute any amount in excess of the amount by which the total price at
which Registrable Securities sold by such Electing Holder exceeds the amount of any damages that such Electing 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. 
 (f) Remedies Not Exclusive. The remedies provided for in this Section 5 are not exclusive and shall not limit any rights or
remedies that may otherwise be available to any indemnified party at law or in equity. 
 (g) Survival of
Provisions. The indemnity and contribution provisions contained in this Section 5 shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on
behalf of any Electing Holder or any person controlling any Electing Holder, or by or on behalf of the Company, its officers or directors or any person controlling the Company and (iii) any sale of the Registrable Securities pursuant to the
Shelf Registration Statement. 
 6. Underwritten Offering. Any Holder who desires to do so may sell Registrable Securities (in whole
or in part) in an underwritten offering; provided that (i) the Electing Holders of at least 33-1/3% in aggregate principal amount of the Registrable Securities then covered by the Shelf Registration Statement shall request such an
offering and (ii) at least such aggregate principal amount of such Registrable Securities shall be included in such offering; and provided further that the Company shall not be obligated to cooperate with more than one underwritten
offering during the Registration Period. Upon receipt of such a request, the Company shall provide all Holders written notice of the request, which notice shall inform such Holders that they have the opportunity to participate in the offering. In
any such underwritten offering, the Managing Underwriters will be selected by, and the underwriting arrangements with respect thereto (including the size of the offering) will be approved by, the holders of a majority of the Registrable Securities
to be included in such offering; provided, however, that such Managing Underwriters and underwriting arrangements must be reasonably satisfactory to the Company. No Holder may participate in any underwritten offering contemplated
hereby unless (a) such Holder agrees to sell such Holder’s Registrable Securities to be included in the underwritten offering in accordance with any approved underwriting arrangements, (b) such Holder completes and executes all
reasonable questionnaires, powers of attorney, indemnities, underwriting agreements, lock-up letters and other documents required under the terms of such approved underwriting arrangements, and (c) if such Holder is not then an Electing Holder,
such Holder returns a completed and signed Notice and Questionnaire to the Company in accordance with Section 3(a)(ii) hereof within a reasonable amount of time before such underwritten offering. Notwithstanding the foregoing, upon receipt of a
request from the Managing Underwriters or a representative of holders of a majority of the Registrable Securities to be included in an 

  

 -13- 








 
underwritten offering to prepare and file an amendment or supplement to the Shelf Registration Statement and Prospectus in connection with an underwritten
offering, the Company may delay the filing of any such amendment or supplement for up to 30 days if the Board of Directors of the Company shall have determined in good faith that the Company has a bona fide business reason for such delay.

 7. Additional Interest. 
 (a) The occurrence of any of the following will constitute an “Event of Default” hereunder: 
 (i) the Company fails to file a Shelf Registration Statement with the Commission on or prior to the 90th day following the Closing Date; 
 (ii) such Shelf Registration Statement is not declared effective by the Commission on or prior to the 180th day following the Closing
Date; 
 (iii) the Company fails to file a post-effective amendment to the Shelf Registration Statement, or the post-effective
amendment is not declared effective, within the periods required by Section 3(a)(ii) hereof; or 
 (iv) the Shelf
Registration Statement ceases to be effective (or the Company prevents or restricts Holders from effecting sales pursuant thereto) for more than 45 days, whether or not consecutive, in any 90-day period, or for more than 90 days, whether or not
consecutive, during any 365-day period. In calculating the 45 or 90 day period, days on which the Company has been obligated to pay Additional Interest in respect of a prior Event of Default under this clause (iv) within the applicable 90-day
or 365-day period, as the case may be, shall not be included. 
 (b) Upon the occurrence of any Event of Default, the Company
shall be required to pay additional interest (“Additional Interest”) at a rate per annum equal to one-quarter of one percent (0.25%) of the aggregate principal amount of Registrable Securities, from and including the Default Date
(as hereinafter defined) to but excluding the Default Termination Date (as hereinafter defined) (the “Default Period”); provided, however, that if the Default Period exceeds 90 days, from and after the 91st day after the Default Date such Additional Interest shall accrue at a rate per annum equal to one-half of one percent (0.50%)
of the aggregate principal amount of Registrable Securities. The term “Default Date” shall mean: (i) with respect to clause (i) of Section 7(a) above, the 91st calendar day following the Closing Date; (ii) with respect to clause (ii) of Section 7(a) above, the 181st calendar day following the Closing Date; (iii) with respect to clause (iii) of Section 7(a) above, the first day following the date
upon which the post-effective amendment was required to be filed or declared effective, as the case may be, pursuant to Section 3(a)(ii) above; and (iv) with respect to clause (iv) of Section 7(a) above, the 46th day of such
90-day period or the 91st day of such 365-day period, as the case may be. The term “Default Termination
Date” shall mean (x) with respect to clauses (i) through (iii) of Section 7(a) above, the date the Shelf Registration Statement or the post-effective amendment, as the case may be, is either so filed or so filed and
subsequently declared effective, as the case may be, and (y) with respect to clause (iv) of Section 7(a) above, the date the Shelf 

  

 -14- 








 
Registration Statement again becomes effective or the Holders of Registrable Securities are again able to make sales under the Shelf Registration Statement.
Notwithstanding the foregoing, no Additional Interest shall accrue as to any Registrable Security from and after the earlier of (1) the date such security is no longer a Registrable Security and (2) the expiration of the Registration
Period. 
 (c) Any amounts to be paid as Additional Interest shall be paid semi-annually in arrears, with the first
semi-annual payment due on the first Interest Payment Date (as defined in the Indenture), as applicable, following the applicable Default Date. In determining the amount of Additional Interest to be paid with respect to shares of Common Stock issued
upon conversion of the Securities, the rate set forth in Section 7(b) hereof shall be applied to the Conversion Price(s) (as defined in the Indenture) in effect during the applicable Default Period. 
 (d) Except as provided in Section 8(a) hereof, the Additional Interest shall be the exclusive monetary remedy available to the
Holders for Events of Default. In no event shall the Company be required to pay Additional Interest in excess of the applicable maximum amount of one-half of one percent (0.5%) set forth above, regardless of whether one or multiple Events of Default
exist. 
 8. Miscellaneous. 
 (a) 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 Initial Purchaser and the
Holders from time to time may be irreparably harmed by any such failure, and accordingly agree that the Initial Purchaser and such Holders, in addition to any other remedy to which they may be entitled at law or in equity and without limiting the
remedies available to the Electing Holders under Section 7 hereof, shall be entitled to compel specific performance of the obligations of the Company under this Agreement in accordance with the terms and conditions of this Agreement, in any
court of the United States or any State thereof having jurisdiction. 
 (b) Amendments and Waivers. The provisions of
this Agreement may not be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given, except by the Company and the written consent of the Holders of a majority in principal amount of the
Registrable Securities then outstanding (provided that holders of Common Stock issued upon conversion of Securities shall not be deemed holders of Common Stock, but shall be deemed to be holders of the aggregate principal amount of Securities from
which such Common Stock was converted). Each Holder of Registrable Securities outstanding at the time of any such amendment, waiver or consent or thereafter shall be bound by any amendment, modification, supplement, waiver or consent effected
pursuant to this Section 8(b). 
 (c) Notices. All notices and other communications provided for or permitted
hereunder shall be given as provided in the Indenture. 
 (d) Parties in Interest. The parties to this Agreement intend
that all Holders of Registrable Securities shall be entitled to receive the benefits of this Agreement and that any Electing Holder shall be bound by the terms and provisions of this Agreement by reason of such 

  

 -15- 








 
election with respect to the Registrable Securities which are included in a Shelf Registration Statement. All the terms and provisions of this Agreement
shall be binding upon, shall inure to the benefit of and shall be enforceable by the respective successors and assigns of the parties hereto and any Holder from time to time of the Registrable Securities. In the event that any transferee of any
Holder 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 entitled to receive the benefits of and, if
an Electing Holder, be conclusively deemed to have agreed to be bound by and to perform all of the terms and provisions of this Agreement to the aforesaid extent. 
 (e) Third Party Beneficiaries. The Initial Purchaser (even if the Initial Purchaser is not a Holder of Registrable Securities)
shall be a third party beneficiary to the agreements made hereunder between the Company, on the one hand, and the Holders, on the other hand, and shall have the right to enforce such agreements directly to the extent it deems such enforcement
necessary or advisable to protect its rights or the rights of Holders hereunder. Each Holder of Registrable Securities shall be a third party beneficiary to the agreements made hereunder between the Company, on the one hand, and the Initial
Purchaser, on the other hand, and shall have the right to enforce such agreements directly to the extent it deems such enforcement necessary or advisable to protect its rights hereunder. 
 (f) No Inconsistent Agreements. The Company has not entered into and the Company will not after the date of this Agreement enter
into any agreement which is inconsistent with the rights granted to the Holders of Registrable Securities in this Agreement or otherwise conflicts with the provisions hereof. The rights granted to the Holders hereunder do not and will not for the
term of this Agreement in any way conflict with the rights granted to the holders of the Company’s other issued and outstanding securities under any such agreements. 
 (g) Counterparts. This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same
effect as if the signatures thereto and hereto were upon the same instrument. 
 (h) Headings. The headings of the
sections of this Agreement have been inserted for convenience of reference only and shall not be deemed a part of this Agreement. 
 (i) Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED IN SUCH STATE. 
 (j) Partial Enforceability. The invalidity or unenforceability of any section, paragraph or provision of this Agreement shall not
affect the validity or enforceability of any other section, paragraph or provision hereof. If any section, paragraph or provision of this Agreement is for any reason determined to be invalid or unenforceable, there shall be deemed to be made such
minor changes (and only such minor changes) as are necessary to make it valid and enforceable.

 (k) Entire Agreement. This Agreement is intended by the parties as a final
expression of their agreement and intended to be a complete and exclusive statement of the agreement and understanding of the parties hereto in respect of the subject matter contained herein. There are no restrictions, promises, warranties or
undertakings, other than those set forth or referred to herein with respect to the registration rights granted by the Company with respect to the Registrable Securities. This Agreement supersedes all prior agreements and understandings between the
parties with respect to such subject matter. 
 (l) Survival. The respective indemnities, agreements, representations,
warranties and other provisions set forth in this Agreement or made pursuant hereto shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Electing Holder, any
director, officer or partner of such Holder, or any controlling person of any of the foregoing, and shall survive the transfer and registration of the Registrable Securities of such Holder.
