 SECTION 2. Shelf Registration Statement.
 (a) The Company agrees to file with the SEC as soon as reasonably practicable after the Closing Date, but in no event later than the
Filing Date, a Registration Statement for an offering to be made on a continuous basis pursuant to Rule 415 covering all of the Transfer Restricted Securities or separate Registration Statements for an offering to be made on a continuous basis
pursuant to Rule 415 covering all of the Common Stock and Notes constituting Transfer Restricted Securities, respectively (such Registration Statement or Statements, collectively, the “Shelf Registration Statement”). Each Shelf
Registration Statement shall be on Form S-3 under the Securities Act or another appropriate form selected by the Company permitting registration of such Transfer Restricted Securities for resale by the Holders in the manner or manners reasonably
designated by Holders of a majority in interest of Transfer Restricted Securities being sold. The Company shall not permit any securities other than the Transfer Restricted Securities to be included in any Shelf Registration Statement. The Company
shall use all reasonable efforts to cause each Shelf Registration Statement to be declared effective pursuant to the Securities Act as soon as reasonably practicable following the filing thereof, and to keep each Shelf Registration Statement
continuously effective under the Securities Act for two years after the date on which all of the Notes (including any Additional Notes) are sold by the Company to the Initial Purchasers (including any New Holders) (the “Effectiveness
Period”), or such shorter period ending when there cease to be any Transfer Restricted Securities outstanding. No later than the second Business Day after each Shelf Registration Statement becomes effective, the Company shall file with the SEC
the Prospectus included therein pursuant to Rule 424. 
 (b) Supplements and Amendments. The Company shall use all
reasonable efforts to keep each Shelf Registration Statement continuously effective by supplementing and amending the Shelf Registration Statement if required by the rules, regulations or instructions applicable to the registration form used for
such Shelf Registration Statement, if required by the Securities Act or if reasonably requested by the Holders of a majority in interest of the Transfer Restricted Securities or by any underwriter of such Transfer Restricted Securities. 

(c) Selling Securityholder Information. Each Holder wishing to sell Transfer Restricted Securities pursuant to a Shelf
Registration Statement and related Prospectus agrees to deliver a Notice and Questionnaire that confirms such Holder’s agreement to be bound by the terms of this Agreement and includes such information regarding it and the distribution of its
Transfer Restricted Securities as is required by law to be disclosed by the Holder in the applicable Registration Statement (the “Requisite Information”) to the Company prior to any intended distribution of Transfer Restricted Securities
under the Shelf Registration Statement. The Company shall not be required to include in any Shelf Registration Statement and related Prospectus the Transfer Restricted Securities of any Holder that does not provide the Company with a Notice and
Questionnaire in accordance with this Section 2(c). The Company shall file, within five Business Days after the receipt of a Notice and Questionnaire from any Holder which includes the Requisite Information with respect to such Holder, a
Prospectus supplement pursuant to Rule 424 or otherwise amend or supplement such Registration Statement to include in the Prospectus the Requisite Information as to such Holder (and the Transfer Restricted Securities held by such Holder), and
the Company shall provide such Holder within five Business Days after receipt of such Notice and Questionnaire with a copy of such Prospectus as so amended or supplemented containing the Requisite Information. Each Holder shall promptly notify the
Company of any material changes to the Requisite Information contained in the Notice and Questionnaire provided to the Company by such Holder. If the Company shall fail to file the appropriate supplement or amendment within five Business Days of
receipt of such notice, the Company shall pay the Holder Liquidated Damages in the manner set forth in Section 3. Furthermore, if the filing requires a post-effective amendment to the Registration Statement and such amendment is not declared
effective within 45 Business Days of the filing of the post-effective amendment, the Company shall pay the Holder Liquidated Damages in the manner set forth in Section 3. 
  

 4 








 If any such Registration Statement refers to any Holder by name or otherwise as the holder of any
securities of the Company, then such Holder shall have the right to require, in the event that such reference to such Holder by name or otherwise is not required by the Securities Act or any similar Federal statute then in force, the deletion of the
reference to such Holder in such Registration Statement at any time subsequent to the time that such reference ceases to be required. 
 (d) Material Events; Suspension of Sales. Notwithstanding the provisions contained in this Section 2, in the event that, in the judgment of the Company’s Board of Directors, it is advisable to suspend
use of the Prospectus due to pending corporate developments, public filings with the SEC or similar events, the Company shall promptly deliver a written certificate to each registered Holder, the Trustee, the Transfer Agent and the managing
underwriters, if any, to the effect that the use of the Prospectus is to be suspended until the Company shall deliver a written notice that the use of the Prospectus may be resumed. Thereafter, the use of the Prospectus shall be suspended, and the
Company shall not be required to maintain the effectiveness of, or amend or update the Shelf Registration Statement, or amend or supplement the Prospectus; provided, however, that the Company shall only be permitted to suspend the use of the
Prospectus for a period not to exceed 30 days in any 12-month period. The Company will use its best efforts to ensure that the use of the Prospectus may be resumed as soon as, in the judgment of the Company’s Board of Directors, disclosure
of the material relating to such pending development, filing or event would not have a material adverse effect on the Company. 
 (e) Additional Agreements of Holders. Each Holder agrees not to dispose of Transfer Restricted Securities pursuant to the Shelf Registration Statement without complying with the provisions of paragraph (d) above regarding use of
the Prospectus. Each Holder further agrees that it will comply fully with applicable federal and state securities laws in connection with the distribution of any Transfer Restricted Securities pursuant to the Shelf Registration Statement. Each
Holder further acknowledges having been advised by the Company that applicable federal securities laws prohibit Holders from trading in securities of the Company at any time while in possession of material non-public information about the Company.

 SECTION 3. Liquidated Damages.
 The Company and the Initial Purchasers agree that the Holders will suffer damages if the Company fails to fulfill its obligations pursuant to Section 2 hereof and that it would not be possible to ascertain the extent of such damages.
Accordingly, the Company hereby agrees to pay liquidated damages (“Liquidated Damages”) to each Holder under the circumstances and to the extent set forth below: 
 (i) if the Shelf Registration Statement has not been filed with the SEC on or prior to the Filing Date; or 
 (ii) if each Shelf Registration Statement is not declared effective by the SEC on or prior to the applicable Effectiveness Target Date; or

 (iii) any Shelf Registration Statement ceases to be effective or usable at any time during the Effectiveness Period
(without being succeeded on the same day immediately by a post-effective amendment or supplement to such Registration Statement that cures such failure and that is itself, in the case of post-effective amendment, immediately declared effective) for
a period of time which shall exceed 30 days in the aggregate in any period of 365 consecutive days (any of the foregoing, a “Registration Default”). 
 In the event of a Registration Default, the Company will pay Liquidated Damages to each holder of Notes constituting or convertible into Transferred Restricted Securities, for the period immediately following the
occurrence of such Registration Default on the outstanding principal amount of such Notes at a rate of the Liquidated Damages Rate. The “Liquidated Damages Rate” shall mean (A) for periods that only include business days on or before
the day that is 60 days after the commencement of a Registration Default, 0.25% per annum, (B) for periods that only include days after the date that is 60 days after the commencement of a Registration Default, 0.50% per annum, and
(C) for periods that include days both before and after the date that is 60 days after the commencement of a Registration Default, a percentage equal to a fraction, the numerator of which shall 

  

 5 








 
be the sum of (i) the number of days in such period that are on or before the date that is 60 days after the commencement of such Registration Default
multiplied by 0.25% and (ii) the number of days in such period that are after the date that is 60 days after the commencement of such Registration Default multiplied by 0.50% and the denominator of which shall be the total number of days
comprising such period. Following the cure of a Registration Default, Liquidated Damages will cease to accrue with respect to such Registration Default (without in any way limiting the effect of any subsequent Registration Default). The rate of
accrual of Liquidated Damages with respect to any period shall not exceed the rate provided for in this paragraph notwithstanding the occurrence of multiple concurrent Registration Defaults. All accrued Liquidated Damages shall be paid to the
holders of Notes constituting or convertible into Transfer Restricted Securities, pursuant to the terms of the Indenture with respect to the payment of interest. 
 The Company shall notify the Transfer Agent or the Trustee, as the case may be, within one Business Day after each and every date on which a Registration Default occurs. Liquidated Damages shall be paid by the Company
to the Record Holders of the Notes on each semiannual interest payment date together with interest to be paid on the Notes pursuant to the terms of the Indenture, by wire transfer of immediately available funds to the accounts specified by them or
by mailing checks to their registered addresses as they appear in the Notes Register (as defined in the Indenture) if no such accounts have been specified in the Notice and Questionnaire on or before the Damages Payment Date; provided, however, that
any Liquidated Damages accrued with respect to any Notes or portion thereof called for redemption on a redemption date, repurchased on a repurchase date, or converted into shares of Common Stock on a conversion date prior to the Damages Payment Date
shall, in any such event, be paid instead to the Holder who submitted such Notes or portion thereof for redemption, repurchase or conversion on the applicable redemption date, repurchase date or conversion date, as the case may be, on such date.

 SECTION 4. Registration Procedures. In connection with the Company’s registration obligations hereunder, the Company
shall effect such registrations on the appropriate form selected by the Company to permit the resale of Transfer Restricted Securities in accordance with the intended method or methods of disposition thereof, and pursuant thereto the Company shall
as expeditiously as reasonably possible: 
 (a) No fewer than five Business Days prior to the initial filing of a Registration
Statement or Prospectus and no fewer than two Business Days prior to the filing of any amendment or supplement thereto (excluding, unless requested, any document that would be incorporated or deemed to be incorporated therein by reference and then
only to the Holder who so requested), furnish to the Holders and the managing underwriters, if any, copies of all such documents proposed to be filed (excluding, unless requested, those incorporated or deemed to be incorporated by reference and then
only to the Holder who so requested) and cause the officers and directors of the Company, counsel to the Company and independent certified public accountants to the Company to respond to such inquiries as shall be necessary in connection with such
Registration Statement, in the opinion of counsel to such underwriters, to conduct a reasonable investigation within the meaning of the Securities Act. The Company shall not file any such Registration Statement or related Prospectus or any
amendments or supplements thereto (excluding any document that would be incorporated or deemed incorporated by reference) to which the Holders of a majority in interest of the Transfer Restricted Securities or the managing underwriters, if any,
shall reasonably object on a timely basis; 
 (b) Prepare and file with the SEC such amendments, including post-effective
amendments, to each Registration Statement as may be necessary to keep such Registration Statement continuously effective for the applicable time period set forth in Section 2(a) hereof; cause the related Prospectus to be supplemented by any
required Prospectus supplement, and as so supplemented to be filed pursuant to Rule 424 under the Securities Act and the Exchange Act with respect to the disposition of all securities covered by such Registration Statement during such period in
accordance with the intended method or methods of disposition by the Holder set forth in such Registration Statement as so amended or in such Prospectus as so supplemented (including, without limitation, the filing of any Prospectus supplement
pursuant to Rule 424 in order to add or change any selling security holder information (including any such supplements or amendments pursuant to Section 2(c) hereof, provided such Holder to which such change applies complies with the
Requisite Information requirements of Section 2(c) hereof)); 
  

 6 








 (c) Notify the Holders and the managing underwriters, if any, promptly (and in the case
of an event specified by clause (i)(A) of this paragraph in no event fewer than two Business Days prior to such filing), and (if requested by any such person), confirm such notice in writing, (i) (A) when a Prospectus or any
Prospectus supplement or post-effective amendment is proposed to be filed, and, (B) with respect to a Registration Statement or any post-effective amendment, when the same has become effective; (ii) of any request of the SEC or any other
Federal or state governmental authority for amendments or supplements to such Registration Statement or related Prospectus or for additional information related thereto; (iii) of the issuance by the SEC, any state securities commission, any
other governmental agency or any court of any stop order, order or injunction suspending or enjoining the use or the effectiveness of the Registration Statement or the initiation of any proceedings for that purpose; (iv) if at any time any of
the representations and warranties of the Company contained in any agreement (including any underwriting agreement) contemplated by Section 4(m) hereof are not true and correct in all material respects; (v) of the receipt by the Company of
any notification with respect to the suspension of the qualification or exemption from qualification of any of the Transfer Restricted Securities for sale in any jurisdiction, or the initiation or threatening of any proceeding for such purpose; and
(vi) of the existence of any fact and the happening of any event that makes any statement made in such Registration Statement or related Prospectus untrue in any material respect, or that requires the making of any changes in such Registration
Statement or Prospectus so that in the case of the Registration Statement, it will not contain any 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 not
misleading and that, in the case of the Prospectus, such Prospectus will not contain any 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 light of
the circumstances under which they were made, not misleading; 
 (d) Use all reasonable efforts to avoid the issuance of, or,
if issued, to obtain the withdrawal of any stop order or order enjoining or suspending the use or effectiveness of a Registration Statement or the lifting of any suspension of the qualification (or exemption from qualification) of any of the
Transfer Restricted Securities for sale in any jurisdiction, at the earliest practicable moment; 
 (e) If requested by the
managing underwriters, if any, or the Holders of a majority in interest of the Transfer Restricted Securities being sold in connection with such offering, (i) promptly include in a Prospectus supplement or post-effective amendment such
information as the managing underwriters, if any, and such Holders agree should, in their reasonable judgment, be included therein; and (ii) make all required filings of such Prospectus supplement or such post-effective amendment as soon as
reasonably practicable after the Company has received notification of the matters to be included in such Prospectus supplement or post-effective amendment, provided, however, that the Company shall not be required to take any action pursuant to this
Section 4(e) that, in the opinion of counsel for the Company, would violate applicable law; 
 (f) Furnish to each Holder
who so requests and each managing underwriter, if any, without charge, at least one conformed copy of each Registration Statement and each amendment thereto, including financial statements (but excluding schedules, all documents incorporated or
deemed to be incorporated therein by reference and all exhibits, unless requested in writing by such Holder or any managing underwriter); 
 (g) Deliver to each Holder and the underwriters, if any, without charge, as many copies of the Prospectus or Prospectuses (including each form of Prospectus) and each amendment or supplement thereto as such persons
may reasonably request; and, unless the Company shall have given notice to such Holder pursuant to Section 2(d), the Company hereby consents to the use of such Prospectus and each amendment or supplement thereto by each of the selling Holders
of Transfer Restricted Securities and the underwriters, if any, in connection with the offering and sale of the Transfer Restricted Securities covered by such Prospectus and any amendment or supplement thereto, provided, however, that no Holder
shall be entitled to use the Prospectus unless and until such Holder shall have furnished to the Company any and all Requisite Information pursuant to Section 2(c) hereof; 
 (h) Use all reasonable efforts to register or qualify, or cooperate with the Holders of Transfer Restricted Securities to be sold or
tendered for, the underwriters, if any, and their respective counsel in connection with 

  

 7 








 
the registration or qualification (or exemption from such registration or qualification) of, such Transfer Restricted Securities for offer and sale under the
securities or Blue Sky laws of such jurisdictions within the United States as any Holder or underwriter reasonably requests in writing, keep each such registration or qualification (or exemption therefrom) effective during the period such
Registration Statement is required to be kept effective and do any and all other acts or things necessary legally to enable the disposition in such jurisdictions of the Transfer Restricted Securities covered by the applicable Registration Statement;
provided, however, that the Company shall not be required to qualify generally to do business in any jurisdiction where it is not then so qualified, take any action that would subject it to general service of process in any such jurisdiction where
it is not then so subject or subject the Company to any tax in any such jurisdiction where it is not then so subject; 
 (i)
In connection with any sale or transfer of Transfer Restricted Securities that will result in such securities no longer being Transfer Restricted Securities, cooperate with the Holders and the managing underwriters, if any, to (i) facilitate
the timely preparation and delivery of certificates representing Transfer Restricted Securities to be sold, which certificates shall not bear any restrictive legends, shall bear a CUSIP number different from the CUSIP number for the Transfer
Restricted Securities and shall be in a form eligible for deposit with The Depository Trust Company; and (ii) enable such Transfer Restricted Securities to be in such denominations and registered in such names as the managing underwriters, if
any, or Holders may reasonably request at least two Business Days prior to any sale of Transfer Restricted Securities; 
 (j)
Use all reasonable efforts to cause the offering of the Transfer Restricted Securities covered by the Registration Statement to be registered with or approved by such other governmental agencies or authorities within the United States, except as may
be required as a consequence of the nature of a Holder’s business, in which case the Company will cooperate in all reasonable respects and at such Holder’s expense with the filing of such Registration Statement and the granting of such
approvals as may be reasonably necessary to enable the seller or sellers thereof or the underwriters, if any, to consummate the disposition of such Transfer Restricted Securities; provided, however, that the Company shall not be required to register
the Transfer Restricted Securities in any jurisdiction that would require the Company to qualify to do business in any jurisdiction where it is not then so qualified, subject it to general service of process in any such jurisdiction where it is not
then so subject or subject the Company to any tax in any such jurisdiction where it is not then so subject or to; 
 (k) Upon
the occurrence of any event contemplated by Section 4(c)(vi) hereof, as promptly as reasonably practicable (subject to any suspension of sales pursuant to Section 2(d) hereof), prepare a supplement or amendment, including, if appropriate,
a post-effective amendment, to each Registration Statement or a supplement to the related Prospectus or any document incorporated or deemed to be incorporated therein by reference, and file any other required document so that, as thereafter
delivered, such Prospectus will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made,
not misleading; 
 (l) Prior to the effective date of the first Registration Statement relating to the Transfer Restricted
Securities, to provide a CUSIP number for the Transfer Restricted Securities to be sold pursuant to the Registration Statement; 
 (m) Enter into such agreements (including any underwriting agreements in form, scope and substance as are customary in underwritten offerings) reasonably satisfactory to the Company and take all such other reasonable actions in connection
therewith (including those reasonably requested by the managing underwriters, if any, or the Holders of a majority in interest of the Transfer Restricted Securities being sold) in order to expedite or facilitate the sale of such Transfer Restricted
Securities; provided, however, that the Company is not required to facilitate an underwritten offering without its consent. In connection with any underwritten offering or otherwise at the reasonable request of the Holders in the context of the
securities laws, the Company will (i) make such representations and warranties to the Holders of such Transfer Restricted Securities and the underwriters, if any, with respect to the business of the Company and its 

  

 8 








 
subsidiaries (including with respect to businesses or assets acquired or to be acquired by any of them), and the Registration Statement, Prospectus and
documents, if any, incorporated or deemed to be incorporated by reference therein, in each case, in form, substance and scope as are customarily made by issuers to underwriters in underwritten offerings and reasonably acceptable to the Company, and
confirm the same if and when requested; (ii) seek to obtain opinions of counsel to the Company and updates thereof (which counsel and opinions (in form, scope and substance) shall be reasonably satisfactory to the managing underwriters, if any,
addressed to each selling Holder of Transfer Restricted Securities and each of the underwriters, if any, covering the matters customarily covered in opinions requested in underwritten offerings (including any such matters as may be reasonably
requested by such underwriters)); (iii) use all reasonable efforts to obtain customary “cold comfort” letters and updates thereof from the independent certified public accountants of the Company (and, if necessary, any other
independent certified public accountants of any subsidiary of the Company or of any business acquired by the Company for which financial statements and financial data are, or are required to be, included in the Registration Statement), addressed
(where reasonably possible) to each selling Holder of Transfer Restricted Securities and each of the underwriters, if any, such letters to be in customary form and covering matters of the type customarily covered in “cold comfort” letters
in connection with underwritten offerings; (iv) if an underwriting agreement is entered into, the same shall contain indemnification provisions and procedures no less favorable to the selling Holders of Transfer Restricted Securities and the
underwriters, if any, than those set forth in Section 6 hereof (or such other provisions and procedures acceptable to Holders of a majority in interest of the Transfer Restricted Securities covered by such Registration Statement and the
managing underwriters); and (v) deliver such documents and certificates as may be reasonably requested by the Holders of majority interest of the Transfer Restricted Securities being sold or the managing underwriters, if any, to evidence the
continued validity of the representations and warranties made pursuant to clause (i) of this Section 4(m) and to evidence compliance with any customary conditions contained in the underwriting agreement or other agreement entered into by
the Company; 
 (n) Make available for inspection by a representative of the Holders of Transfer Restricted Securities being
sold, any underwriter participating in any such disposition of Transfer Restricted Securities, if any, and any attorney, consultant or accountant retained by such selling Holders or underwriter, at the offices where normally kept, during reasonable
business hours, all financial and other records, pertinent corporate documents and properties of the Company and its subsidiaries as they may reasonably request, and cause the officers, directors, agents and employees of the Company and its
subsidiaries to supply all information in each case reasonably requested by any such representative, underwriter, attorney, consultant or accountant in connection with such Registration Statement, provided, however, that such persons shall 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 or inspection (as the case may be) of such information shall be kept
confidential by such persons, unless (i) disclosure of such information is required by court or administrative order or is necessary to respond to inquiries of regulatory authorities; (ii) disclosure of such information is required by law
(including any disclosure requirements pursuant to Federal securities laws in connection with the filing of any Registration Statement or the use of any Prospectus); (iii) such information becomes generally available to the public other than as
a result of a disclosure or failure to safeguard by any such person; or (iv) such information becomes available to any such person from a source other than the Company and such source is not bound by a confidentiality agreement; 
 (o) Use all reasonable efforts to cause the Indenture to be qualified under the TIA not later than the effective date of the first

such changes, and all other forms and documents (including Form T-1) required to be filed with the SEC to enable the Indenture to be so qualified under the TIA in a timely manner;

underwritten offering; and (ii) if not sold to underwriters in such an offering, commencing on the first day of the first fiscal quarter after the effective date of a Registration Statement, which statement shall cover said period, consistent

 (q) list all shares of Common Stock covered by any Registration Statements on
any securities exchange on which the Common Stock is then listed, and use its reasonable efforts to maintain at all times the listing of the Common Stock on the NASDAQ Global Market or another national securities exchange (including by complying
with the rules and regulations thereof). 
 SECTION 5. Registration Expenses. All fees and expenses incident to the performance
of or compliance with this Agreement by the Company shall be borne by it whether or not any Registration Statement is filed or becomes effective and whether or not any securities are offered or sold pursuant to any Registration Statement. The fees
and expenses referred to in the foregoing sentence shall include, without limitation, (i) all registration and filings fees (including, without limitation, fees and expenses (A) with respect to filings required to be made with the National
Association of Securities Dealers, Inc. and (B) in compliance with securities or Blue Sky laws (including, without limitation and in addition to that provided for in this Section 5, fees and disbursements of counsel for the underwriters in
connection with Blue Sky qualifications of the Transfer Restricted Securities and determination of the eligibility of the Transfer Restricted Securities for investment under the laws of such jurisdictions as the managing underwriters, if any, or
Holders of a majority in interest of Transfer Restricted Securities, may designate)); (ii) printing expenses (including, without limitation, of printing Prospectuses if the printing of Prospectuses is required by the managing underwriters, if
any, or by the Holders of a majority in interest of the Transfer Restricted Securities included); (iii) messenger, telephone and delivery expenses; (iv) reasonable fees and disbursements of counsel for the Company (plus any local counsel
deemed appropriate by the Holders of a majority in interest of the Transfer Restricted Securities) in accordance with the provisions of Section 5 hereof; (v) fees and disbursements of all independent certified public accountants referred
to in Section 4(m)(iii) (including, without limitation, the expenses of any special audit and “comfort” letters required by or incident to such performance); (vi) fees and expenses of all other persons retained by the Company. In
addition, the Company shall pay its internal expenses (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties), the expense of an annual audit and the fees and expenses incurred
in connection with the listing of the securities to be registered on any securities exchange. Notwithstanding anything in this Agreement to the contrary, each Holder shall pay all underwriting discounts and brokerage commissions with respect to any
Transfer Restricted Securities sold by it. 
 SECTION 6. Indemnification.
 (a) The Company agrees to indemnify and hold harmless (i) each of the Initial Purchasers; (ii) each Holder; (iii) each
person, if any, who controls (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) any of the foregoing (any of the persons referred to in this clause (iii) being hereinafter referred to as a
“controlling person”); and (iv) the respective officers, directors, partners, employees, representatives and agents of the Initial Purchasers, the Holders (including predecessor Holders), or any controlling person (any person referred
to in clause (i), (ii), (iii) or (iv) may hereinafter be referred to as an “Indemnified Person”), from and against any and all losses, claims, damages, liabilities, expenses and judgments caused by any untrue statement or
alleged untrue statement of a material fact contained in any Registration Statement or Prospectus or in any amendment or supplement thereto or in any preliminary 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 the case of any 

  

 10 








 
Prospectus, or preliminary or free writing prospectus, or supplement thereto, in light of the circumstances under which they were made) not misleading,
except insofar as such losses, claims, damages, liabilities, expenses or judgments are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to any Indemnified Person furnished to the
Company by or on behalf of such Indemnified Person expressly for use therein (which shall include, without limitation, the Requisite Information in the Notice and Questionnaire provided to the Company by such Indemnified Person 
 (b) In case any action shall be brought against any Indemnified Person, based upon any Registration Statement or any such Prospectus or
any amendment or supplement thereto and with respect to which indemnity may be sought against the Company, such Indemnified Person shall promptly notify the Company in writing and the Company shall assume the defense thereof, including the
employment of counsel reasonably satisfactory to such Indemnified Person and payment of all fees and expenses. Any Indemnified Person shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the
fees and expenses of such counsel shall be at the expense of such Indemnified Person, unless (i) the employment of such counsel shall have been specifically authorized in writing by the Company; (ii) the Company shall have failed to assume
the defense and employ counsel; or (iii) such Indemnified Person or Persons shall have been advised by counsel that there may be a conflict between the positions of the indemnifying party or parties and of the indemnified party or parties in
conducting the defense of such action or proceeding or that there may be legal defenses available to such Indemnified Person or Persons different from or in addition to those available to the indemnifying party or parties (in which case the Company
shall not have the right to assume the defense of such action on behalf of such Indemnified Person, it being understood, however, that the Company shall not, in connection with any one such action or separate but substantially similar or related
actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) for all such Indemnified Persons, which
firm shall be designated in writing by such Indemnified Persons, and that all such fees and expenses shall be reimbursed as they are incurred). The Company shall not be liable for any settlement of any such action effected without its written
consent but if settled with the written consent of the Company, the Company agrees to indemnify and hold harmless any Indemnified Person from and against any loss or liability by reason 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. 
 (c) In connection with any Registration Statement pursuant to which any Holder (or predecessor Holder) sold or offered for resale Transfer
Restricted Securities, such Holder agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, officers, employees, representatives and agents and any person controlling the Company within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act, to the same extent as the foregoing indemnity from the Company to each Indemnified Person but only with reference to information relating to such Indemnified Person
furnished by or on behalf of such Indemnified Person expressly for use in such Registration Statement (which shall include, without limitation, the Requisite Information in the Notice and Questionnaire provided to the Company by such Indemnified
Person). In case any action shall be brought against the Company, any of its directors, officers, employees, representatives and agents, or any person controlling the Company based on such Registration Statement and in respect of which indemnity may
be sought against any Indemnified Person, the Indemnified Person shall have the rights and duties given to the Company (except that if the Company shall have assumed the defense thereof, such Indemnified Person shall not be required to do so, but
may employ separate counsel therein and participate in defense thereof but the fees and expenses of such counsel shall be at the expense of such Indemnified Person), and the Company, its directors, officers, employees, representatives and agents,
and any person controlling the Company shall have the rights and duties given to the Indemnified Person by Section 6(b) hereof. 
  

 11 








 (d) If the indemnification provided for in this Section 6 is applicable by its terms
but unavailable to an indemnified party in respect of any losses, claims, damages, liabilities, expenses or judgments referred to therein, then each indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount
paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities, expenses and judgments (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and
each Indemnified Person on the other hand pursuant to the applicable Exchange Agreement or from the offering for resale of the Transfer Restricted Securities or (ii) if the allocation provided by clause (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 (i) above but also the relative fault of the Company and each such Indemnified Person in connection with the statements or
omissions which resulted in such losses, claims, damages, liabilities, expenses or judgments, as well as any other relevant equitable considerations. The relative fault of the Company and each such Indemnified Person shall be determined by reference
to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the Company or such Indemnified Person and the parties’ relative intent,
knowledge, access to information and opportunity to correct or prevent such statement or omission. 
 The Company, the Holders and the
Initial Purchasers agree that it would not be just and equitable if contribution pursuant to this Section 6(d) were determined by pro rata allocation (even if the Indemnified Person were treated as one entity for such purpose) or by any other
method of allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities, expenses
or judgments referred to in the immediately preceding paragraph 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 6, no Indemnified Person shall be required to contribute any amount or make any other payment or otherwise incur any liability under this Section 6 in
excess of the amount by which the total net profit received by it in connection with the sale of the Transfer Restricted Securities pursuant to this Agreement exceeds the amount of any damages which such Indemnified Person 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 Indemnified Persons’ obligations to contribute pursuant to this Section 6(d) are several in proportion to the respective amount of Transfer Restricted Securities
included in and sold pursuant to any such Registration Statement by each Indemnified Person and not joint. 
 SECTION 7. Underwritten
Registration. If any of the Transfer Restricted Securities covered by any Shelf Registration Statement are to be sold in an underwritten offering, the investment banker or investment bankers and manager or managers that will administer the
offering will be investment bankers of recognized national standing selected by the Holders of a majority in interest of such Transfer Restricted Securities included in such offering, subject to the consent of the Company (which will not be
unreasonably withheld or delayed). 
 No person may participate in any underwritten registration hereunder unless such person (i) agrees
to sell such person’s Transfer Restricted Securities on the basis reasonably provided in any underwriting arrangements approved by the persons entitled hereunder to approve such arrangements; and (ii) completes and executes all
questionnaires, powers of attorney, indemnities, underwriting agreements, lock-up agreements and other documents reasonably required under the terms of such underwriting arrangements. 
 SECTION 8. Miscellaneous.
 (a) Remedies. In the event of a breach by the Company or by a Holder of any of their respective obligations under this Agreement, each Holder or the Company, in addition to being entitled to exercise all rights granted by law,
including, without limitation, recovery of damages, will be entitled to specific 

  

 12 








 
performance of its rights under this Agreement. The Company and each Holder agree that monetary damages would not be adequate compensation for any loss
incurred by reason of a breach by it of any of the provisions of this Agreement and hereby further agree that, in the event of any action for specific performance in respect of such breach, they shall waive the defense that a remedy at law would be
adequate. 
 (b) No Inconsistent Agreements. The Company shall not enter into any agreement with respect to its
securities that is inconsistent with the rights granted to the Holders in this Agreement or otherwise conflicts with the provisions hereof. The Company is not currently a party to any agreement granting any registration rights with respect to any of
its securities to any person which conflicts with the Company’s obligations hereunder or gives any other party the right to include any securities in any Registration Statement filed pursuant hereto, except for such rights and conflicts as have
been irrevocably waived. 
 (c) No Adverse Action Affecting the Transfer Restricted Securities. The Company will not
take any action with respect to the Transfer Restricted Securities which would adversely affect the ability of any of the Holders to include such Transfer Restricted Securities in a registration undertaken pursuant to this Agreement. 
 (d) No Piggyback on Registrations. After the date hereof, the Company shall not grant to any of its security holders (other than
the Holders in such capacity) the right to include any of its securities in any Shelf Registration Statement. 
 (e)
Amendments and Waivers. The provisions of this Agreement, including the provisions of this sentence, may not be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof, may not be given, without the
written consent of the Holders of a majority in interest of the Transfer Restricted Securities, provided, however, that, for the purposes of this Agreement, Transfer Restricted Securities that are owned, directly or indirectly, by either the Company
or an Affiliate of the Company are not deemed outstanding. Notwithstanding the foregoing, a waiver or consent to depart from the provisions hereof with respect to a matter that relates exclusively to the rights of Holders whose Transfer Restricted
Securities are being sold pursuant to an underwritten offering and that does not directly or indirectly affect the rights of other Holders may be given by Holders of a majority in interest of the Transfer Restricted Securities being sold by such
Holders pursuant to such an underwritten offering, provided, however, that the provisions of this sentence may not be amended, modified, or supplemented except in accordance with the provisions of the immediately preceding sentence. Notwithstanding
the foregoing two sentences, this Agreement may be amended by written agreement signed by the Company and the Initial Purchasers, without the consent of the Holders of Restricted Securities, to cure any ambiguity or to correct or supplement any
provision contained herein that may be defective or inconsistent with any other provision contained herein, or to make such other provisions in regard to matters or questions arising under this Agreement that shall not adversely affect the interests
of the Holders of Restricted Securities. In addition, notwithstanding the foregoing three sentences, if after the date hereof the Company enters into one or more Exchange Agreements to issue additional Notes (the “Additional Notes”) to
such persons or entities as the Company in its sole discretion may determine (each, a “New Holder”), such New Holder may, upon execution and delivery by such New Holder of a signature page to an Exchange Agreement and this Agreement,
become an Initial Purchaser under this Agreement, entitled to the benefits and subject to the obligations hereunder, and this Agreement may be amended without the consent of any Holder solely to make such New Holder an Initial Purchaser party hereto
and to update Exhibit A hereto to reflect the name of and principal amount of Notes issued to such New Holder. Each Holder of Restricted Securities outstanding at the time of any such amendment, modification, supplement, waiver or consent or
thereafter shall be bound by any such amendment, modification, supplement, waiver or consent effected pursuant to this Section 8(e), whether or not any notice, writing or marking indicating such amendment, modification, supplement, waiver or
consent appears on the Restricted Securities or is delivered to such Holder. 
  

 13

 (g) Successors and Assigns. This Agreement
shall inure to the benefit of and be binding upon the successors and permitted assigns of each of the parties and shall inure to the benefit of each existing and future Holder. The Company may not assign its rights or obligations hereunder without
the prior written consent of the Holders of a majority in interest of the Transfer Restricted Securities, other than by operation of law pursuant to a merger or consolidation to which the Company is a party. 
 (h) Counterparts. This Agreement may be executed in any number of counterparts by the parties hereto, each of which when so
executed shall be deemed to be an original and all of which taken together shall constitute one and the same instrument.

result as that contemplated by such term, provision, covenant or restriction. It is hereby stipulated and declared to be the intention of the parties that they would have executed the remaining terms, provisions, covenants and restrictions without
including any of such that may be hereafter declared invalid, illegal, void or unenforceable. 
 (k) Headings. The
headings in this Agreement are for convenience of reference only and shall not limit or otherwise affect the meaning hereof. All references made in this Agreement to “Section” and “paragraph” refer to such Section or paragraph of

available remedy. 
 (m) Reports Under the 1934 Act. With a view to making available to the Holders the benefits of
Rule 144 promulgated under the Securities Act or any other similar rule or regulation of the SEC that may at any time permit the Investors to sell securities of the Company to the public without registration (“Rule 144”), the
Company agrees to:

 14 








 (ii) file with the SEC in a timely manner all annual reports on Form 10-K or 10-KSB, and

and 
 (iii) furnish to each Holder so long as such Investor owns Transfer Restricted Securities, promptly upon written
request, (i) a written statement by the Company, if true, that it has complied with the reporting requirements of Rule 144, the Securities Act and the Exchange Act, (ii) a copy of the most recent annual or quarterly report of the Company
and such other reports and documents so filed by the Company, and (iii) such other information as may be reasonably requested to permit the Holders to sell such securities pursuant to Rule 144 without registration.
