 2 Registration Under the Securities Act. 
  
 (a) Except as set forth in Section 2(b) below, the Company
agrees to file under the Securities Act as soon as practicable, but in no event later than 60 days following the Closing Date, a registration statement 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, which debt securities are substantially
identical to the Securities (and are entitled to the benefits of trust indenture which are substantially identical to the Indenture or is the Indenture and which has been qualified under the Trust Indenture Act), except that they have been
registered pursuant to an effective registration statement under the Securities Act and do not contain provisions for the additional interest contemplated in Section 2(c) below (such new debt securities hereinafter called “Exchange
Securities”). The Company agrees to use all commercially reasonable efforts to cause the Exchange Registration Statement to become effective under the Securities Act at the earliest possible time, but in no event later than 180 days
following the Closing Date. The Exchange Offer will be registered under the Securities Act on the appropriate form and will comply with all applicable tender offer rules and regulations under the Exchange Act. The Company further agrees to use its
best efforts to commence and complete the Exchange Offer on the earliest practicable date, but no later than 30 Business Days after such registration statement has become effective, hold the Exchange Offer open for at least 20 Business Days and
exchange Exchange Securities for all Registrable Securities that have been properly tendered and not withdrawn on or prior to the expiration of the Exchange Offer. The Exchange Offer will be deemed to have been “completed” only if the debt
securities received by holders other than Restricted Holders in the 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 

  

 4 








 
Offer, Exchange Securities for all Registrable Securities that have been properly tendered and not withdrawn before the expiration of the Exchange Offer,
which shall be on a date that is at least 20 days following the commencement 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 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 225 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 on or prior to 45 days after such filing obligation 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 all commercially reasonable efforts (x) to cause the Shelf Registration Statement to become or be declared effective on or prior to 90 days following the filing of
such Shelf Registration Statement 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, 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 Business Days following 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 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, subject to the provisions of Section 9(b), special interest (“Special Interest”), in addition to the Base Interest, shall accrue in an amount equal to $0.05 per week per $1,000 in
principal amount at maturity of Registrable Securities for each week or portion thereof that the Registration Default Period continues for the first 90-day period immediately following the occurrence of such Registration Default. The amount of the
liquidated damages shall increase by an additional $0.05 per week per $1,000 in principal amount at maturity of Registrable Securities with respect to each subsequent 90-day period until all Registration Defaults have been cured, up to a maximum
amount of liquidated damages for all Registration Defaults of $.50 per week per $1,000 in principal amount at maturity of Registrable Securities. 
  
 (d) The Company shall take all actions necessary or advisable to be taken by it to ensure that the transactions contemplated herein are
effected as so contemplated. 
  
 (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.

 (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 

  

 14 








 
meaning of the Conduct Rules (the “Conduct Rules”) of the National Association of Securities Dealers, Inc.
(“NASD”) 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, and (C) providing such information to such broker-dealer as may be required in order for such broker-dealer to comply with the requirements of the Conduct Rules; 
  
 (xx) comply with all applicable rules and regulations of the
Commission, and shall make generally available to its securityholders within eighteen months after the effective date of such Shelf Registration Statement, an earning statement (which need not be audited) of the Company and its subsidiaries
complying with Section 11(a) of the Securities Act (including, at the option of the Company, Rule 158 thereunder); and 
  
 (xxi) if the Securities have been rated prior to the initial sale of the Securities, use its best efforts to confirm that such ratings
will apply to the Registrable Securities covered by a Shelf Registration Statement, or (B) if the Securities were not previously rated, use commercially reasonable efforts to cause the Registrable Securities covered by the Shelf Registration
Statement to be rated with the appropriate rating agencies, if so requested by the Majority Holders. 
  
 (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 

  

 15 








 
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, 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) Until the expiration of two years after the Closing Date, the Company will not, and will not permit any of its “affiliates”
(as defined in Rule 144) to, resell any of the Securities that have been reacquired by any of them except pursuant to an effective registration statement under the Securities Act. 
  
 4 Registration Expenses. 
  
 The Company agrees to bear and to pay or cause to be paid promptly all expenses incident to the Company’s performance of or compliance with this
Agreement, including (a) all Commission and any NASD registration, filing and review fees and expenses including fees and disbursements of counsel for the Majority Holders in connection with such registration, filing and review, (b) all fees and

reimburse such person for the full amount of the Registration Expenses so incurred, assumed or paid promptly after receipt of a request therefor. Notwithstanding the 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 counsel or other advisors or experts retained by such holders (severally or
jointly), other than the counsel and experts specifically referred to above. 
  
 5 Representations and Warranties. 
  
 The Company represents and warrants to, and agrees with, the 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(d) or Section 3(c) 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(d)(viii)(F) or Section 3(c)(iii)(F) hereof until (ii) such time as the Company 

  

 17 








 
furnishes an amended or supplemented prospectus pursuant to Section 3(e) or Section 3(c)(iv) hereof, each such registration statement, and each prospectus
(including any summary prospectus) contained therein or furnished pursuant to Section 3(d) or Section 3(c) 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 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, nor will such action result in any violation of the provisions of the certificate of incorporation, as amended, or the by-laws of the Company or 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; and no consent, approval, authorization, order, registration or qualification of or with any such court or governmental agency or body is required
for the consummation by the Company of the transactions contemplated by this Agreement, except the registration under the Securities Act of the Securities, qualification of the Indenture under the Trust Indenture Act and such consents, approvals,
authorizations, registrations or qualifications as may be required under State securities or blue sky laws in connection with the offering and distribution of the Securities.

 6 Indemnification. 
  
 (a) Indemnification by the Company. The Company 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 an 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 preliminary, final or summary prospectus contained therein or furnished by the Company to any such holder, Electing Holder or
underwriter, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein 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 the Company shall not 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 Electing Holders of such Registrable Securities included in any registration statement filed pursuant to Section 2(b) and 2(a) hereof and each person who participates as an
underwriter in any offering of such Registrable Securities, severally and not jointly, agrees to (i) indemnify and hold harmless the Company and all other holders of Registrable Securities, against any losses, claims, damages or liabilities to which
the Company 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 an untrue
statement or alleged untrue statement of a material fact contained in such registration statement, or any preliminary, final or summary prospectus contained therein or furnished by the Company to any such Electing Holder, agent or underwriter, or
any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein 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 for any legal or other expenses reasonably incurred by the Company in 

  

 19 








 
connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that no such Electing Holder or
underwriter 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 Section 6 (a) or (b) hereof 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; but the failure to so notify the indemnifying party will not relieve
the indemnifying party from liability under Section 6 (a) or (b) hereof unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses. In
case any such action shall be brought against any indemnified party and it shall notify an indemnifying party of the commencement thereof, such indemnifying party shall be entitled to participate therein and, to the extent that it shall wish,
jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the
indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, such indemnifying party shall not be liable to such indemnified party for any legal expenses of other
counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. 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) hereof 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 to 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 

  

 20 








 
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 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 under this Section 6 shall be in addition to any liability which the
Company 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 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 the Majority Holders 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. 
  

 21 








 (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. 
  
 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 Sections 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. 
  
 9 Miscellaneous. 
  
 (a) No Inconsistent Agreements. The Company represents, warrants, covenants and agrees that it has not granted, and shall not
grant, registration rights with respect to Registrable Securities or any other securities which would be inconsistent with the terms contained in this Agreement. 
  
 (b) 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 Purchaser and the holders from time to time of the Registrable Securities may be irreparably harmed by any such failure, and accordingly agree that the Purchaser and
such holders, in addition to any other remedy to which they may be entitled at law or in equity, 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. 
  
 (c) Notices. All notices, requests, claims, demands, waivers and other communications hereunder shall be in writing and shall be
deemed to have been duly given when received as follows: if to (i) the Company, to it at 510 Bering Drive, Suite 500, Houston, Texas 77057; (ii) a holder, to it at the address of such holder set forth in 

  

 22 








 
the security register or other records of the Company; or (iii) to such other address as the Company or any such holder may have furnished to the other in
writing in accordance herewith; provided, that notices of change of address shall be effective only upon receipt. 
  
 (d) Parties in Interest. All the terms and provisions of this Agreement shall be binding upon, shall inure to the benefit of and
shall be enforceable by the parties hereto and the holders from time to time of the Registrable Securities and the respective successors and assigns of the parties hereto and such holders. In the event that any transferee of any holder of
Registrable Securities 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 deemed a beneficiary hereof
for all purposes and such Registrable Securities shall be held subject to all of the terms of this Agreement, and by taking and holding such Registrable Securities such transferee shall be entitled to receive the benefits of, and be conclusively
deemed to have agreed to be bound by all of the applicable terms and provisions of this Agreement. If the Company shall so request, any such successor, assign or transferee shall agree in writing to acquire and hold the Registrable Securities
subject to all of the applicable terms hereof. 
  
 (e) Survival. The respective indemnities, agreements, representations, warranties and each other provision set forth in this Agreement or made pursuant hereto shall remain in full force and effect regardless of any investigation (or
statement as to the results thereof) made by or on behalf of any holder of Registrable Securities, any director, officer or partner of such holder, any agent or underwriter or any director, officer or partner thereof, or any controlling person of
any of the foregoing, and shall survive delivery of and payment for the Registrable Securities pursuant to the Purchase Agreement and the transfer and registration of Registrable Securities by such holder and the consummation of an Exchange Offer.

  
 (f) Governing Law. This Agreement
shall be governed by and construed in accordance with the laws of the State of New York. 
  
 (g) Headings. The descriptive headings of the several Sections and paragraphs of this Agreement are inserted for convenience only,
do not constitute a part of this Agreement and shall not affect in any way the meaning or interpretation of this Agreement. 
  
 (h) Entire Agreement; Amendments. This Agreement and the other writings referred to herein (including the Indenture and the form of
Securities) or delivered pursuant hereto which form a part hereof contain the entire understanding of the parties with respect to its subject matter. This Agreement supersedes all prior agreements and understandings between the parties with respect
to its subject matter. This Agreement may be amended and the observance of any term of this Agreement may be waived (either generally or in a particular instance and either retroactively or prospectively) only by a written instrument duly executed
by the Company and the Majority Holders of the Registrable Securities at the time outstanding. Each holder of any Registrable Securities 

  

 23 








 
at the time or thereafter outstanding shall be bound by any amendment or waiver effected pursuant to this Section 9(h), whether or not any notice, writing or
marking indicating such amendment or waiver appears on such Registrable Securities or is delivered to such holder. 
  
 (i) Inspection. For so long as this Agreement shall be in effect, this Agreement and a complete list of the names and addresses of
all the holders of Registrable Securities shall be made available for inspection and copying on any business day by any holder of Registrable Securities for proper purposes only (which shall include any purpose related to the rights of the holders
of Registrable Securities under the Securities, the Indenture and this Agreement) at the offices of the Company at the address thereof set forth in Section 9(c) above and at the office of the Trustee under the Indenture. 
  
 (j) Counterparts. This agreement may be executed by
the parties in counterparts, each of which shall be deemed to be an original, but all such respective counterparts shall together constitute one and the same instrument. 
  

 24 








 (k) If the foregoing is in accordance with your understanding, please sign and return to
us ten counterparts hereof, and upon the acceptance hereof by you, this letter and such acceptance hereof shall constitute a binding agreement between the Purchaser and the Company.
