relating to an offer to exchange (such registration statement, the “Exchange Registration Statement”, and such offer, the “Exchange Offer”) any and all of the Securities for a like aggregate principal amount of debt securities
issued by the Company and guaranteed by the Guarantors, which debt securities and guarantees are substantially identical to the Securities and the related Guarantees, respectively (and are entitled to the benefits of a trust indenture which is

 4 







 
Exchange Offer for Registrable Securities are, upon receipt, transferable by each such holder without restriction under the Securities Act and the Exchange Act and without material restrictions
under the blue sky or securities laws of a substantial majority of the States of the United States of America. The Exchange Offer shall be deemed to have been completed upon the earlier to occur of (i) the Company having exchanged the Exchange
Securities for all outstanding Registrable Securities pursuant to the Exchange Offer and (ii) the Company having exchanged, pursuant to the Exchange Offer, Exchange Securities for all Registrable Securities that have been validly tendered and
not validly withdrawn before the expiration of the Exchange Offer. The Company agrees (x) to include in the Exchange Registration Statement a prospectus for use in any resales by any holder of Exchange Securities that is a broker-dealer and
(y) to keep such Exchange Registration Statement effective for a period (the “Resale Period”) beginning when Exchange Securities are first issued in the Exchange Offer and ending upon the earlier of the expiration of the 180th day
after the Exchange Offer has been completed or such time as such broker-dealers no longer own any Registrable Securities. With respect to such Exchange Registration Statement, such holders shall have the benefit of the rights of indemnification and
contribution set forth in Sections 6(a), (c), (d) and (e) hereof. 
 (b) If (i) on or prior to the time
the Exchange Offer is completed existing Commission interpretations are changed such that the debt securities or the related guarantees received by holders other than Restricted Holders in the Exchange Offer for Registrable Securities are not or
would not be, upon receipt, transferable by each such holder without restriction under the Securities Act, (ii) the Exchange Offer has not been completed within 240 days following the Closing Date or (iii) the Exchange Offer is not
available to any holder of the Securities, the Company shall, in lieu of (or, in the case of clause (iii), in addition to) conducting the Exchange Offer contemplated by Section 2(a), file under the Securities Act as soon as practicable, but no
later than 30 days after the time such obligation to file arises, a “shelf” registration statement providing for the registration of, and the sale on a continuous or delayed basis by the holders of, all of the Registrable Securities,
pursuant to Rule 415 or any similar rule that may be adopted by the Commission (such filing, the “Shelf Registration” and such registration statement, the “Shelf Registration Statement”). The Company agrees to use its reasonable
best efforts (x) to cause the Shelf Registration Statement to become or be declared effective no later than 120 days after such Shelf Registration Statement is filed and to keep such Shelf Registration Statement continuously effective for a
period ending on the earlier of the second anniversary of the Effective Time or such time as there are no longer any Registrable Securities outstanding, provided, however, that no holder shall be entitled to be named as a selling
securityholder in the Shelf Registration Statement or to use the prospectus forming a part thereof for resales of Registrable Securities unless such holder is an Electing Holder, and (y) after the Effective Time of the Shelf Registration
Statement, promptly upon the request of any holder of Registrable Securities that is not then an Electing Holder, to take any action reasonably necessary to enable such holder to use the prospectus forming a part thereof for resales of Registrable
Securities, including, without limitation, any action necessary to identify such holder as a selling securityholder in the Shelf Registration Statement, provided, however, that nothing in this Clause (y) shall relieve any such holder of
the obligation to return a completed and signed Notice and Questionnaire to the Company in accordance with Section 3(d)(iii) hereof. The Company further agrees to supplement or make amendments to the Shelf Registration Statement, as and when
required by the rules, regulations or instructions applicable to the registration form used by the Company for such Shelf Registration Statement or by the Securities Act or rules and regulations thereunder for shelf registration, and the Company
agrees to furnish to each Electing Holder copies of any such supplement or amendment prior to its being used or promptly following its filing with the Commission.

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

 (xiv) unless any Registrable Securities shall be in book-entry only form, cooperate with the Electing Holders and the
managing underwriters, if any, to facilitate the timely preparation and delivery of certificates representing Registrable Securities to be sold, and which certificates shall not bear any restrictive legends; and, in the case of an underwritten
offering, enable such Registrable Securities to be in such denominations and registered in such names as the managing underwriters may request at least two business days prior to any sale of the Registrable Securities; 

(xv) provide a CUSIP number for all Registrable Securities that are sold pursuant to the Shelf Registration Statement, not later

number; 
 (xvi) enter into one or more underwriting agreements, engagement letters, agency agreements, “best

proposed or effected, as the case may be; 
 (xix) in the event that any broker-dealer registered under the Exchange Act
shall underwrite any Registrable Securities or participate as a member of an underwriting syndicate or selling group or “assist in the distribution” (within the meaning of the Conduct Rules (the “Conduct Rules) of the Financial
Industry Regulatory Authority (“FINRA”) or any successor thereto, as amended from time to time) thereof, whether as a holder of such Registrable Securities or as an underwriter, a placement or sales agent or a broker or dealer in respect
thereof, or otherwise, assist such broker-dealer in complying with the requirements of such Conduct Rules, including by (A) if such Conduct Rules shall so require, engaging a “qualified independent underwriter” (as defined in such
Conduct Rules) to participate in the preparation of the Shelf Registration Statement relating to such Registrable Securities, to exercise usual standards of due diligence in respect thereto and, if any portion of the offering contemplated by such
Shelf Registration Statement is an underwritten offering or is made through a placement or sales agent, to recommend the yield of such Registrable Securities, (B) indemnifying any such qualified independent underwriter to the extent of the
indemnification of underwriters provided in Section 6 hereof (or to such other customary extent as may be requested by such underwriter), and (C) providing such information to such broker-dealer as may be required in order for such

 (xx) comply with all applicable rules and regulations of the Commission, and make

Section 11(a) of the Securities Act (including, at the option of the Company, Rule 158 thereunder). 
 (e) In the
event that the Company would be required, pursuant to Section 3(d)(viii)(F) above, to notify the Electing Holders, the placement or sales agent, if any, therefor and the managing underwriters, if any, thereof, the Company shall without delay
prepare and furnish to each of the Electing Holders, to each placement or sales agent, if any, and to each such underwriter, if any, a reasonable number of copies of a prospectus supplemented or amended so that, as thereafter delivered to purchasers
of Registrable Securities, such prospectus shall conform in all material respects to the applicable requirements of the Securities Act and the Trust Indenture Act and the rules and regulations of the Commission thereunder and shall not contain an
untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing. Each Electing Holder agrees that upon receipt
of any notice from the Company pursuant to Section 3(d)(viii)(F) hereof, such Electing Holder shall forthwith discontinue the disposition of Registrable Securities pursuant to the Shelf Registration Statement applicable to such Registrable
Securities until such Electing Holder shall have received copies of such amended or supplemented prospectus, and if so directed by the Company, such Electing Holder shall deliver to the Company (at the Company’s expense) all copies, other than
permanent file copies which shall not be distributed, then in such Electing Holder’s possession of the prospectus covering such Registrable Securities at the time of receipt of such notice. 

(f) In the event of a Shelf Registration, in addition to the information required to be provided by each Electing Holder in its
Notice and Questionnaire, the Company may require such Electing Holder to furnish to the Company such additional information regarding such Electing Holder and such Electing Holder’s intended method of distribution of Registrable Securities as
may be required in order to comply with the Securities Act. Each such Electing Holder agrees to notify the Company as promptly as practicable of any inaccuracy or change in information previously furnished by such Electing Holder to the Company or
of the occurrence of any event in either case as a result of which any prospectus relating to such Shelf Registration contains or would contain an untrue statement of a material fact regarding such Electing Holder or such Electing Holder’s
intended method of disposition of such Registrable Securities or omits to state any material fact regarding such Electing Holder or such Electing Holder’s intended method of disposition of such Registrable Securities required to be stated
therein or necessary to make the statements therein not misleading in light of the circumstances then existing, and promptly to furnish to the Company any additional information required to correct and update any previously furnished information or
required so that such prospectus shall not contain, with respect to such Electing Holder or the disposition of such Registrable Securities, an untrue statement of a material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein not misleading in light of the circumstances then existing. 
 (g) The Company
will not, and will not permit any of its affiliates (as defined in Rule 144 under the Securities Act) to, resell any of the Securities that have been acquired by any of them, except for Securities purchased by the Company or any of its affiliates
and resold in a transaction registered under the Securities Act.

foregoing, the holders of the Registrable Securities being registered shall pay all agency fees and commissions and underwriting discounts and commissions attributable to the sale of such Registrable Securities and the fees and disbursements of any

 5. Representations and Warranties. 

1. The Company and the Guarantors, jointly and severally, represent and warrant to, and agree with, each Purchaser and each of the holders from
time to time of Registrable Securities that: 
 (a) Each registration statement covering Registrable Securities and each
prospectus (including any preliminary or summary prospectus) contained therein or furnished pursuant to Section 3(c) or Section 3(d) hereof and any further amendments or supplements to any such registration statement or prospectus, when it
becomes effective or is filed with the Commission, as the case may be, and, in the case of an underwritten offering of Registrable Securities, at the time of the closing under the underwriting agreement relating thereto, will conform in all material
respects to the requirements of the Securities Act and the Trust Indenture Act and the rules and regulations of the Commission thereunder and will not contain an untrue statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein not misleading; and at all times subsequent to the Effective Time when a prospectus would be required to be delivered under the Securities Act, other than from (i) such time as a notice
has been given to holders of Registrable Securities pursuant to Section 3(c)(iii)(F) or Section 3(d)(viii)(F) hereof until (ii) such time as the Company furnishes an amended or supplemented prospectus pursuant to Section 3(c)(iv)
or Section 3(e) hereof, each such registration statement, and each prospectus (including any summary prospectus) contained therein or furnished pursuant to Section 3(c) or Section 3(d) hereof, as then amended or supplemented, will
conform in all material respects to the requirements of the Securities Act and the Trust Indenture Act and the rules and regulations of the Commission thereunder and will not contain an untrue statement of a material fact or omit to state a material
fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing; provided, however, that this representation and warranty shall not apply to any statements or
omissions made in reliance upon and in conformity with information furnished in writing to the Company by a holder of Registrable Securities expressly for use therein. 

(b) Any documents incorporated by reference in any prospectus referred to in Section 5(a) hereof, when they become or became
effective or are or were filed with the Commission, as the case may be, will conform or conformed in all material respects to the requirements of the Securities Act or the Exchange Act, as applicable, and none of such documents will contain or
contained an untrue statement of a material fact or will omit or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading; provided, however, that this representation and
warranty shall not apply to any statements or omissions made in reliance upon and in conformity with information furnished in writing to the Company by a holder of Registrable Securities expressly for use therein. 

(c) The compliance by the Company with all of the provisions of this Exchange and Registration Rights Agreement and the consummation
of the transactions herein contemplated will not conflict with or result in a breach of any of the terms or provisions of, or constitute a default under, any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to
which the Company or any subsidiary of the Company is a party or by which the Company or any subsidiary of the Company is bound or to which any of the property or assets of the Company or any subsidiary of the Company is subject, other than any such
conflict, breach or default that, individually or in the aggregate, would not have a Material Adverse Effect (as such term is defined in the Purchase Agreement); nor will such action result in any violation of the provisions of the certificate of
incorporation, by-laws or other organizational document of the Company or any Guarantor; nor will such action result in any violation of any statute or any order, rule or regulation of any court or governmental agency or body having jurisdiction
over the Company or any subsidiary of the Company or any of their properties, other than any such violation that, individually or in the aggregate, would not have a Material Adverse Effect; and no consent, approval,


  
 17 







 
authorization, order, registration or qualification of or with any such court or governmental agency or body is required for the consummation by the Company and the Guarantors of the transactions

(d) This Exchange and Registration Rights Agreement has been duly authorized, executed and delivered by the Company and the
Guarantors. 
 6. Indemnification. 
 (a) Indemnification by the Company and the Guarantors. The Company and the Guarantors, jointly and severally, will indemnify and hold harmless each of the holders of Registrable Securities included in an
Exchange Registration Statement, each of the Electing Holders of Registrable Securities included in a Shelf Registration Statement and each person who participates as a placement or sales agent or as an underwriter in any offering or sale of such
Registrable Securities against any losses, claims, damages or liabilities, joint or several, to which such holder, agent or underwriter may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities
(or actions in respect thereof) arise out of or are based upon (1) any untrue statement or alleged untrue statement of a material fact contained in any Exchange Registration Statement or Shelf Registration Statement, as the case may be, under
which such Registrable Securities were registered under the Securities Act, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein not misleading, or
(2) any untrue statement or alleged untrue statement of a material fact contained in any preliminary, final or summary prospectus contained therein or furnished by the Company to any such holder, Electing Holder, agent or underwriter, or any
amendment or supplement thereto, or any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, and will reimburse
such holder, such Electing Holder, such agent and such underwriter for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such action or claim as such expenses are incurred; provided,
however, that neither the Company nor any Guarantor shall be liable to any such person in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement
or omission or alleged omission made in such registration statement, or preliminary, final or summary prospectus, or amendment or supplement thereto, in reliance upon and in conformity with written information furnished to the Company by such person
expressly for use therein. 
 (b) Indemnification by the Holders and any Agents and Underwriters. The Company may
require, as a condition to including any Registrable Securities in any registration statement filed pursuant to Section 2(b) hereof and to entering into any underwriting agreement with respect thereto, that the Company shall have received an
undertaking reasonably satisfactory to it from the Electing Holder of such Registrable Securities and from each underwriter named in any such underwriting agreement, severally and not jointly, to (i) indemnify and hold harmless the Company, the
Guarantors, and all other holders of Registrable Securities, against any losses, claims, damages or liabilities to which the 

  
 18 







 
Company, the Guarantors or such other holders of Registrable Securities may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or
actions in respect thereof) arise out of or are based upon (1) any untrue statement or alleged untrue statement of a material fact contained in any Exchange Registration Statement or Shelf Registration Statement, as the case may be, under which
such Registrable Securities were registered under the Securities Act, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein not misleading, or
(2) any untrue statement or alleged untrue statement of a material fact contained in any preliminary, final or summary prospectus contained therein or furnished by the Company to any such holder, Electing Holder, agent or underwriter, or any
amendment or supplement thereto, or any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case to
the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by such Electing Holder or
underwriter expressly for use therein, and (ii) reimburse the Company and the Guarantors for any legal or other expenses reasonably incurred by the Company and the Guarantors in connection with investigating or defending any such action or
claim as such expenses are incurred; provided, however, that no such Electing Holder shall be required to undertake liability to any person under this Section 6(b) for any amounts in excess of the dollar amount of the proceeds to be
received by such Electing Holder from the sale of such Electing Holder’s Registrable Securities pursuant to such registration. 
 (c) Notices of Claims, Etc. Promptly after receipt by an indemnified party under subsection (a) or (b) above of written notice of the commencement of any action, such indemnified party shall, if a
claim in respect thereof is to be made against an indemnifying party pursuant to the indemnification provisions of or contemplated by this Section 6, notify such indemnifying party in writing of the commencement of such action; provided
that the failure to notify the indemnifying party shall not relieve it from any liability that it may have under Sections 6(a) or 6(b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or
defenses) by such failure; and provided, further, that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under Sections 6(a) or 6(b) hereof. If any
such proceeding shall be brought or asserted against an indemnified party and it shall have notified the indemnifying party thereof, the indemnifying party shall retain counsel reasonably satisfactory to the indemnified party (who shall not, without
the consent of the indemnified party, be counsel to the indemnifying party) to represent the indemnified party and any others entitled to indemnification pursuant to this Section 6 that the indemnifying party may designate in such proceeding
and shall pay the fees and expenses of such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. 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 contrary; (ii) the indemnifying party has failed within a
reasonable time to retain counsel reasonably satisfactory to the indemnified party; (iii) the indemnified party shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those
available to the indemnifying party; or (iv) the named parties in 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 

  
 19 







 
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
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. Any such separate firm (x) for any Purchaser, its affiliates, directors and officers and any
control persons of such Purchaser shall be designated in writing by J.P. Morgan Securities LLC, (y) for any holder, its directors and officers and any control Persons of such holder shall be designated in writing by the holders of the majority
of the aggregate principal amount of the outstanding Registrable Securities, and (z) for the Company, the Guarantors, their respective directors and officers and any control persons of the Company and the Guarantors shall be designated in
writing by the Company. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in
respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional
release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of any indemnified party.

 (d) Contribution. If for any reason the indemnification provisions contemplated by Section 6(a) or
Section 6(b) are unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to
the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the
indemnified party in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative fault of such
indemnifying party and indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information
supplied by such indemnifying party or by such indemnified party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties hereto agree that it would not be
just and equitable if contributions pursuant to this Section 6(d) were determined by pro rata allocation (even if the holders or any agents or underwriters or all of them were treated as one entity for such purpose) or by any other method of
allocation which does not take account of the equitable considerations referred to in this Section 6(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages, or liabilities (or actions in respect
thereof) referred to above shall be deemed to include any legal or other fees or expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this
Section 6(d), no holder shall be required to contribute any amount in excess of the amount by which the dollar amount of the proceeds received by such holder from the sale of any Registrable Securities (after deducting any fees, discounts and
commissions applicable thereto) exceeds the amount of any damages which such holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission, and no underwriter shall be required to
contribute any amount in excess of the amount by which the total price at which the Registrable Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such


  
 20 







 
underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The holders’ and any underwriters’ obligations in this Section 6(d) to
contribute shall be several in proportion to the principal amount of Registrable Securities registered or underwritten, as the case may be, by them and not joint. 

(e) The obligations of the Company and the Guarantors under this Section 6 shall be in addition to any liability which the
Company or the Guarantors may otherwise have and shall extend, upon the same terms and conditions, to each officer, director and partner of each holder, agent and underwriter and each person, if any, who controls any holder, agent or underwriter
within the meaning of the Securities Act; and the obligations of the holders and any agents or underwriters contemplated by this Section 6 shall be in addition to any liability which the respective holder, agent or underwriter may otherwise
have and shall extend, upon the same terms and conditions, to each officer and director of the Company or any Guarantor (including any person who, with his consent, is named in any registration statement as about to become a director of the Company
or any Guarantor) and to each person, if any, who controls the Company within the meaning of the Securities Act. 
 7. Underwritten
Offerings. 
 (a) Selection of Underwriters. If any of the Registrable Securities covered by the Shelf
Registration are to be sold pursuant to an underwritten offering, the managing underwriter or underwriters thereof shall be designated by Electing Holders holding at least a majority in aggregate principal amount of the Registrable Securities to be
included in such offering, provided that such designated managing underwriter or underwriters is or are reasonably acceptable to the Company. 
 (b) Participation by Holders. Each holder of Registrable Securities hereby agrees with each other such holder that no such holder may participate in any underwritten offering hereunder unless such holder
(i) agrees to sell such holder’s Registrable Securities on the basis provided in any underwriting arrangements approved by the persons entitled hereunder to approve such arrangements and (ii) completes and executes all questionnaires,
powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements. 
 8. Rule 144. 
 1. The Company covenants to the holders of Registrable Securities that to the
extent it shall be required to do so under the Exchange Act, the Company shall timely file the reports required to be filed by it under the Exchange Act or the Securities Act (including the reports under Section 13 and 15(d) of the Exchange Act
referred to in subparagraph (c)(1) of Rule 144 adopted by the Commission under the Securities Act) and the rules and regulations adopted by the Commission thereunder, and shall take such further action as any holder of Registrable Securities may
reasonably request, all to the extent required from time to time to enable such holder to sell Registrable Securities without registration under the Securities Act within the limitations of the exemption provided by Rule 144 under the Securities
Act, as such Rule may be amended from time to time, or any similar or successor rule or regulation hereafter adopted by the Commission. Upon the request of any holder of Registrable Securities in connection with that holder’s sale pursuant to
Rule 144, the Company shall deliver to such holder a written statement as to whether it has complied with such requirements. 

  
 21 







 9. Miscellaneous.
