 2. DEMAND REGISTRATION RIGHTS. 
 2.1 Request for Registration. On or

under the Securities Act of the Registrable Securities and shall use its commercially reasonable efforts to have the Registration Statement declared effective by the Commission by the later of (x) July 15, 2013 and (y) two hundred and
twenty five (225) days from the date hereof. In addition, at any time and from time to time on or after the date that is ninety (90) days from the date hereof, a Holder or Holders may make a written demand requiring the Company to effect
the Registration under the Securities Act of all or part of its Registrable Securities (a “Demand Registration”), and thereupon the Company shall be required to effect such Registration pursuant to and subject to the terms herein.
Any demand for a Demand Registration shall specify the number of Registrable Securities proposed to be sold and the intended method(s) of distribution thereof. The Company shall not be obligated to (i) effect more than an aggregate of two
(2) Demand Registrations in respect of all Registrable Securities, including no more than one (1) Demand Registration in any six-month period, or (ii) effect any Demand Registration where the aggregate price to the public of the
Registrable Securities proposed to be sold by a Holder or Holders is less than $20 million. 
 2.2 Effective
Registration. A Registration will not count as a Demand Registration until the Registration Statement filed with the Commission with respect to such Demand Registration has been declared effective and the Company has complied with all of its
obligations under this Agreement with respect thereto; provided, however, that if, after such Registration Statement has been declared effective and during the Registration Period the offering of Registrable Securities pursuant to a Demand
Registration is interfered with by any stop order or injunction of the Commission or any other governmental agency or court, the 

  
 3 








 
Registration Statement with respect to such Demand Registration will be deemed not to have been declared effective, unless and until, such stop order or injunction is removed, rescinded or
otherwise terminated; and provided, further, that the Company shall not be obligated to file a second Registration Statement until a Registration Statement that has been filed is counted as a Demand Registration or is terminated. 

2.3 Underwritten Offering. If the demanding Holders so advise the Company as part of its written demand for a Demand Registration,
the offering of such Registrable Securities pursuant to such Demand Registration may be in the form of an underwritten offering. In such event, the lead Underwriter to administer the offering will be chosen by such Holders, subject to the prior
written consent of the Company, such consent not to be unreasonably withheld or delayed. The Company subsequently shall enter into an underwriting agreement in customary form with the Underwriter or Underwriters selected for such underwriting
pursuant to this Section 2.3. 
 2.4 Withdrawal. A Holder may elect to withdraw from an offering by giving written
notice to the Company and the Underwriter or Underwriters of its request to withdraw prior to the effectiveness of the Registration Statement filed with the Commission with respect to such Demand Registration and such Registration shall not count as
a Demand Registration provided for in Section 2.1. 
 3. REGISTRATION PROCEDURES. 

3.1 Filings; Information. Subject to the requirements of the first sentence of Section 2.1, whenever the Company is required
to effect the Registration of any Registrable Securities pursuant to Section 2, the Company shall use its commercially reasonable efforts to effect the Registration and sale of such Registrable Securities in accordance with the intended
method(s) of distribution thereof as expeditiously as practicable (and in any event with one hundred eighty (180) days after receipt of a request for a Demand Registration pursuant to Section 2.1 (the “Effective Date”),
and in connection with any such request: 
 3.1.1. (a) Filing Registration Statement. The Company shall, as
expeditiously as practicable (and in any event within ninety (90) days after receipt of a request for a Demand Registration pursuant to Section 2.1) prepare and file with the Commission a Registration Statement on any form for which the
Company then qualifies or which counsel for the Company shall deem appropriate and which form shall be available for the resale of all Registrable Securities to be registered thereunder in accordance with the intended method(s) of distribution
thereof; provided, that the Company agrees that, at the request of the Holders, at such time as the Company becomes a “well-known seasoned issuer,” as such term is defined in Rule 405 under the Securities Act (a
“WKSI”), the Company shall register an offering pursuant to Section 2 on an “automatic shelf registration statement,” as such term is defined in Rule 405 under the Securities Act (an “Automatic Shelf
Registration Statement”) on Form S-3; provided further, that the Company shall not be required to file an Automatic Shelf Registration Statement if a Registration Statement on Form S-3 covering the Registrable Securities is already
effective. The Company shall use its commercially reasonable efforts to cause any Registration Statement to become and remain effective for the period required by Section 3.1.3, subject to the Company’s rights under Section 3.1.3;
provided, however, that the Company shall have the right to defer any 

  
 4 








 
Demand Registration for up to forty-five (45) days, if the Company shall furnish to the Holders a certificate signed by the Chief Executive Officer or the Chairman of the Board of Directors
of the Company stating that, in the good faith judgment of the Board of Directors of the Company, it would be materially detrimental to the Company and its securityholders for such Registration Statement to be effected at such time because the
Registration would require the Company to make a public disclosure of material, non-public information, disclosure of which, in the Board of Director’s good faith judgment, after consultation with independent outside counsel to the Company,
(i) would be required to be made in any Registration Statement so that such Registration Statement would not be materially misleading and (ii) would not be required to be made at such time but for the filing of such Registration Statement,
and the Company has a bona fide business purpose for not disclosing such information publicly; and provided further, that the Company shall not have the right to exercise the right set forth in the immediately preceding proviso (x) for a
total period of more than forty-five (45) days in any 365-day period in respect of a Demand Registration hereunder or (y) more than once during any 12-month period. 
 (b) The Company shall use its commercially reasonable efforts to not become an ineligible issuer (as defined in Rule 405 under the Securities Act) during any period during which an Automatic Shelf
Registration Statement is effective. If the Company does not pay the filing fee covering the Registrable Securities at the time an Automatic Shelf Registration Statement is filed, the Company agrees to pay such fee at such time or times as the
Registrable Securities are to be sold. If, at any time when the Company is required to re-evaluate its WKSI status, the Company determines that it is not a WKSI, the Company shall use its commercially reasonable efforts to refile the shelf
registration statement on Form S-3 and, if such form is not available, Form S-1 and maintain the effectiveness of such Registration Statement as required in this Agreement. 

(c) Additional Interest. If (i) the Initial Registration Statement has not been declared effective by
the Commission on or prior to the two hundred twenty-fifth (225th) day after the date of this Agreement or any other Registration Statement has not been declared effective by the Commission on or prior to the Effective Date, (ii) a Registration Statement is
filed and declared effective but shall thereafter cease to be effective or fail to be usable for its intended purpose at any time within the Registration Period set forth in Section 3.1.3 below without being succeeded within five
(5) Business Days by a post-effective amendment to the Registration Statement that cures such failure and that is itself immediately declared effective or (iii) prior to or on the 60th day, as the case may be, of any Suspension Period as
set forth in Section 3.1.4 below, such suspension has not been terminated (each such event referred to in clauses (i), (ii) and (iii), a “Registration Default”), the Company agrees to pay Additional Interest
(“Additional Interest”) to each demanding Holder with respect to the first 90-day period immediately following the occurrence of such Registration Default, in the form of increased interest of 0.25% on the principal amount of such
Holder’s Registrable Securities subject to such Demand Registration. The amount of the Additional Interest shall increase by 0.25% after the first 90-day period until all Registration Defaults have been cured; provided that, the Company
shall in no event be required to pay Additional Interest for more than one Registration Default at any given time; and provided further, that in no event shall the Additional Interest accrue at a rate per year exceeding 1.00% of the principal
amount of such Holder’s Registrable Securities. Following the cure of all Registration Defaults relating to any particular Registrable Security, the accrual of Additional Interest with respect to such Registration Default will cease.

 3.1.2. Opportunity to Review. The Company shall, sufficiently in advance of filing
with the Commission a Registration Statement or prospectus, or any amendment or supplement thereto, including documents incorporated by reference, furnish without charge to the Holders and their legal counsel, copies of all such documents proposed
to be filed and provide the Holders and their legal counsel with a reasonable opportunity to review such documents and comment thereon, and shall make such changes to such documents as a Holder or its counsel reasonably request in a timely fashion.

 3.1.3. Amendments and Supplements. The Company shall prepare and file with the Commission such amendments, including
post-effective amendments, and supplements to such Registration Statement and the prospectus used in connection therewith as may be necessary to keep such Registration Statement (or successor Registration Statement) effective and in compliance with
the provisions of the Securities Act until all Registrable Securities and other securities covered by such Registration Statement have been disposed of in accordance with the intended method(s) of distribution set forth in such Registration
Statement (which period shall not exceed the sum of ninety (90) days in the case of a Registration Statement filed with respect to and used solely for a single “one-off” underwritten offering) plus any period during which any such
disposition is interfered with by any stop order or injunction of the Commission or any governmental agency or court) or such securities have been withdrawn (such period, the “Registration Period”). To the extent the Holders seek to
consummate a pro rata distribution of any of their Registrable Securities, the Company agrees to take all actions reasonably requested by the Holders in order to effectuate such distribution, including filing supplements to the Prospectus which name
the distributees if deemed necessary or appropriate. 
 3.1.4. Suspension. Upon (i) the issuance by the Commission
of a stop order suspending the effectiveness of a Registration Statement filed pursuant to Section 2, (ii) the occurrence of any event or the existence of any fact as a result of which a Registration Statement relating to Registrable
Securities would contain any untrue statement of material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading or (iii) the occurrence or existence of any pending
material corporate development that, in the reasonable and good faith opinion of the board of directors of the Company, makes it appropriate to suspend the availability of any such Registration Statement because it would be materially detrimental to
the Company for the Registration to proceed at such time, then the Company shall deliver a notice to the Holders that the availability of such Registration Statement is suspended, as the case may be (a “Suspension Notice”), and,
upon receipt of a Suspension Notice, the Holders agree not to sell any Registrable Securities pursuant to such Registration Statement until the Holders are advised by the Company in writing that the related prospectus may be used to sell the
Registrable Securities, and the Holders have received copies of the supplemental filings or amendments that are incorporated or deemed incorporated by reference to such prospectus. The Company shall use its commercially reasonable efforts to ensure
that the use of such Registration Statement may be resumed, as applicable, (A) in the case of clause (i) above, as promptly as practicable, (B) in the case of clause (ii) above, as soon as, in the reasonable judgment of the
Company, the Registration Statement does 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, and (C) in the case of clause (iii) above, as soon as, in the reasonable discretion of the Company, such suspension is no longer appropriate. The Company shall not be


  
 6 








 
permitted to deliver a Suspension Notice, nor exercise its rights of Suspension under this Section, more than once during any 12 month period, and the period during which any Registration
Statement may be suspended under this Section (the “Suspension Period”) shall not exceed sixty (60) days on any one occasion. 
 3.1.5. Notification. After the filing of a Registration Statement, the Company shall promptly notify the Holders of such filing, and shall further notify the Holders promptly and confirm such
advice in writing of the occurrence of any of the following: (i) when such Registration Statement becomes effective; (ii) when any post-effective amendment to such Registration Statement becomes effective; and (iii) any request by the
Commission for any amendment or supplement to such Registration Statement or any prospectus relating thereto or for additional information or of the occurrence of an event requiring the preparation of a supplement or amendment to such prospectus so
that, as thereafter delivered to the purchasers of the securities covered by such Registration Statement, such prospectus will not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein not misleading, and promptly make available to the Holders included in such Registration Statement any such supplement or amendment. The Company shall promptly send the Holders any comments of the Commission
received by the Company with respect to the Registration Statement and any Company responses to such comments (including comments on documents incorporated by reference into the Registration Statement). 

3.1.6. State Securities Laws Compliance; FINRA. The Company shall use its commercially reasonable efforts to (i) register or
qualify the Registrable Securities covered by the Registration Statement as necessary under such securities or “blue sky” laws of such jurisdictions in the United States as the Holders (in light of their intended plan of distribution) may
request in writing and (ii) take such action necessary to cause such Registrable Securities covered by the Registration Statement to be registered with or approved by such other governmental authorities as may be necessary by virtue of the
business and operations of the Company and do any and all other acts and things that may be necessary or advisable to enable a Holder or Holders to consummate the disposition of such Registrable Securities in such jurisdictions; provided,
however, that the Company shall not be required to qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this paragraph, subject itself to taxation in any such jurisdiction or consent
to general service of process in any such jurisdiction. In addition, the Company shall use its commercially reasonable efforts to file or cause the Registration Statement to be filed with FINRA and, in the event of an offering involving any FINRA
member, secure a no objections letter with respect to the compensation to be paid to any FINRA member. 
 3.1.7. Agreements
for Disposition. The Company shall enter into customary agreements (in customary form, scope and substance) and take such other actions as are reasonably required in order to expedite or facilitate the disposition of such Registrable Securities,
provided, that the Company only shall be required to enter into an underwriting agreement in accordance with the provisions of Section 3.5.1. 
 3.1.8. Cooperation. The Company shall make available its executive officers, as it deems appropriate, to cooperate reasonably in any offering of Registrable Securities hereunder,


  
 7 








 
which cooperation shall include the preparation of the Registration Statement with respect to such offering and all other offering materials and related documents and, in the event of an
underwritten offering, participation in meetings and roadshows with Underwriters, analysts, attorneys, accountants and potential investors. 
 3.1.9. Records. The Company shall make available upon reasonable notice at reasonable time and for reasonable periods for inspection by the Holders, by any Underwriter participating in any
disposition pursuant to such Registration Statement and any attorney, accountant or other professional retained by the Holders or any Underwriter, all financial and other records, pertinent corporate documents and properties of the Company, as shall
be reasonably necessary to enable them to exercise their due diligence responsibility, and cause the Company’s officers, directors and employees to supply all information reasonably requested by any of them in connection with such Registration
Statement; provided that any such Person gaining access to information regarding the Company pursuant to this Section shall agree to keep such information confidential until such information otherwise becomes public, unless disclosure by a
Person is required by law; provided, further, that notwithstanding each Person’s agreement to keep such information confidential, the Holders make no acknowledgement that any such information is material, non-public information.

 3.1.10. Opinions and Comfort Letters. In the case of an underwritten offering pursuant and subject to
Section 2.3, the Company shall furnish to the Holders a signed copy of (i) any opinion of counsel to the Company delivered to any Underwriter and (ii) any comfort letter from the Company’s independent public accountants (or
accountants for any entity acquired by the Company whose financial statements are included in the Registration Statement) delivered to any Underwriter. In the event no legal opinion is delivered to any Underwriter, or in non-underwritten
transactions, the Company shall furnish to the Holders, at any time that the Holders elect to use a prospectus, an opinion of counsel to the Company stating only that the Registration Statement containing such prospectus has been declared effective
and that no stop order is in effect. 
 3.1.11. QIU. The Company shall use its commercially reasonable efforts to cause
the retention of a qualified independent underwriter (QIU) to the extent required by the FINRA rules and regulations with respect to any underwritten offering. 
 3.2 Obligation to Suspend Distribution. Upon receipt of any notice from the Company of the happening of any event of the kind described in Section 3.1.4, or any suspension by the Company
pursuant to a written insider trading compliance program adopted by the Company’s Board of Directors of the ability of all insiders covered by such program to transact in the Company’s securities because of the existence of material
non-public information, the Holders shall discontinue disposition of such Registrable Securities pursuant to the Registration Statement covering such Registrable Securities immediately until it receives the supplemented or amended prospectus
contemplated by Section 3.1.5(iii) or the restriction on the ability of insiders to transact in the Company’s securities is removed, as applicable, and, if so directed by the Company, the Holders will deliver to the Company all copies,
other than permanent file copies then in its possession, of the most recent prospectus covering such Registrable Securities at the time of receipt of such notice.

expenses of the Underwriter required to be borne by the Holders or the Company pursuant to the underwriting agreement pro rata in proportion to the respective amount of Registrable Securities each is selling in such offering. 

3.4 Information. The Holders shall promptly provide such information as may reasonably be requested by the Company or the managing
Underwriter, if any, in connection with the preparation of any Registration Statement, including amendments and supplements thereto, in order to effect the Registration of any Registrable Securities under the Securities Act pursuant to

such Holder furnishes to the Company in writing, within twenty (20) Business Days after receipt of a request therefor, such information as the Company may reasonably request for use in connection with any Registration Statement. Each Holder as

party to, any agreement that is inconsistent with the rights granted to a Holder or Holders by this Agreement.

harmless each Holder, each of its officers, employees, affiliates, directors, partners, members, attorneys and agents and each Person, if any, who controls (within the meaning of Section 15 of the Securities Act or Section 20 of the
Exchange Act) such Holder (each, an “Holder Indemnified Party”) from and against any expenses, losses, judgments, claims, damages or liabilities, whether joint or several, arising out of or based upon any untrue statement (or
allegedly untrue statement) of a material fact contained in any Registration Statement under which the sale of such Registrable Securities was registered under the Securities Act, any preliminary prospectus, final prospectus, any “free writing
prospectus,” as such term is defined in Rule 405 under the Securities Act, or summary prospectus contained in the Registration Statement, or any amendment or supplement thereto, or arising out of or based upon any omission (or alleged omission)
to state a material fact required to be stated therein or necessary to make the statements therein not misleading, or any untrue statement or alleged untrue statement of a material fact in the information conveyed to any purchaser at the time of the
sale to such purchaser, or the omission or alleged omission to state therein a material fact required to be stated therein, or any violation by the Company of the Securities Act or any rule or regulation promulgated thereunder applicable to the
Company and relating to action or inaction required of the Company in connection with any such Registration; and the Company shall promptly advance and/or reimburse the Holder Indemnified Party, as incurred, for any legal and any other expenses
reasonably incurred by such Holder Indemnified Party in connection with investigating 

  
 10 









 
and defending any such expense, loss, judgment, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case to the extent that any
such expense, loss, claim, damage or liability arises out of or is based upon any untrue statement or allegedly untrue statement or omission or alleged omission made in such Registration Statement, preliminary prospectus, final prospectus or summary
prospectus, or any such amendment or supplement, in reliance upon and in conformity with information furnished to the Company, in writing, by such Holder expressly for use therein. The Company also shall indemnify any Underwriter of the Registrable
Securities, their officers, affiliates, directors, partners, members and agents and each Person who controls such Underwriter on substantially the same basis as that of the indemnification provided above in this Section 4.1. 

4.2 Indemnification by the Holders. Each Holder will, in the event that any Registration is being effected under the Securities
Act pursuant to this Agreement of any Registrable Securities held by such selling Holder, indemnify and hold harmless the Company, each of its officers, employees, affiliates, directors, partners, members, attorneys and agents and each Underwriter
(if any), and each other selling Holder and each other Person, if any, who controls such Person within the meaning of the Securities Act, against any losses, claims, judgments, damages or liabilities, insofar as such losses, claims, judgments,
damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or allegedly untrue statement of a material fact contained in any Registration Statement under which the sale of such Registrable Securities
was registered under the Securities Act, any preliminary prospectus, final prospectus, any “free writing prospectus,” as such term is defined in Rule 405 under the Securities Act, or summary prospectus contained in the Registration
Statement, or any amendment or supplement thereto, or arise out of or are based upon any omission or the alleged omission to state a material fact required to be stated therein or necessary to make the statement therein not misleading, if the
statement or omission was made in reliance upon and in conformity with information furnished in writing to the Company by such selling Holder expressly for use therein, or any untrue statement or alleged untrue statement of a material fact in the
information conveyed to any purchaser at the time of the sale to such purchaser, or the omission or alleged omission to state therein a material fact required to be stated therein, and shall reimburse the Company, its directors and officers, and
each other selling holder or controlling Person for any legal or other expenses reasonably incurred by any of them in connection with investigation or defending any such loss, claim, damage, liability or action. 

4.3 Conduct of Indemnification Proceedings. Promptly after receipt by any Person of any notice of any loss, claim, damage or
liability or any action in respect of which indemnity may be sought pursuant to Section 4.1 or 4.2, such Person (the “Indemnified Party”) shall, if a claim in respect thereof is to be made against any other Person for
indemnification hereunder, notify such other Person (the “Indemnifying Party”) in writing of the loss, claim, judgment, damage, liability or action; provided, however, that the failure by the Indemnified Party to
notify the Indemnifying Party shall not relieve the Indemnifying Party from any liability which the Indemnifying Party may have to such Indemnified Party hereunder, except and solely to the extent the Indemnifying Party is actually prejudiced by
such failure. If the Indemnified Party is seeking indemnification with respect to any claim or action brought against the Indemnified Party, then the Indemnifying Party shall be entitled to participate in such claim or action, and, to the extent
that it wishes, jointly with all other Indemnifying Parties, to assume control of the defense thereof with counsel satisfactory to the Indemnified Party. After notice from the

Indemnifying Party to the Indemnified Party of its election to assume control of the defense of such claim or action, the Indemnifying Party shall not be liable to the Indemnified Party for any
legal or other expenses subsequently incurred by the Indemnified Party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that in any action in which both the Indemnified Party and
the Indemnifying Party are named as defendants, the Indemnified Party shall have the right to employ separate counsel (but no more than one such separate counsel) to represent the Indemnified Party and its controlling Persons who may be subject to
liability arising out of any claim in respect of which indemnity may be sought by the Indemnified Party against the Indemnifying Party, with the fees and expenses of such counsel to be paid by such Indemnifying Party if, based upon the advice of
counsel of such Indemnified Party, representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. No Indemnifying Party shall, without the prior written consent of the
Indemnified Party, consent to entry of judgment or effect any settlement of any claim or pending or threatened proceeding in respect of which the Indemnified Party is or could have been a party and indemnity could have been sought hereunder by such
Indemnified Party, unless such judgment or settlement includes an unconditional release of such Indemnified Party from all liability arising out of such claim or proceeding. 
 4.4 Contribution. 
 4.4.1. If the indemnification provided for in the
foregoing Sections 4.1 and 4.2 is unavailable to any Indemnified Party in respect of any loss, claim, damage, liability or action referred to herein, then each such 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 loss, claim, damage, liability or action in such proportion as is appropriate to reflect the relative fault of the Indemnified Parties and the Indemnifying Parties in
connection with the actions or omissions which resulted in such loss, claim, damage, liability or action, as well as any other relevant equitable considerations. The relative fault of any Indemnified Party and any Indemnifying Party shall be
determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by such Indemnified Party or such
Indemnifying Party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. 
 4.4.2. The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 4.4 were determined by pro rata allocation or by any other method of allocation which
does not take account the equitable considerations referred to in the immediately preceding Section. 
 4.4.3. The amount paid
or payable by an Indemnified Party as a result of any loss, claim, damage, liability or action referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses
incurred by such Indemnified Party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 4.4, no Holder shall be required to contribute any amount in excess of the dollar amount
of the net proceeds (after payment of any underwriting fees, discounts, commissions or taxes) actually received by such Holder from the sale of Registrable Securities which gave rise to such contribution obligation, and each


  
 12 









 
Holder shall only be required to contribute if such Holder would have otherwise been required to indemnify under Section 4.2. 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. 
 5. UNDERWRITING AND DISTRIBUTION. 
 5.1 Rule 144. The Company
covenants that it shall file any reports required to be filed by it under the Securities Act and the Exchange Act and shall take such further action as the Holders may reasonably request, all to the extent required from time to time to enable the
Holders to sell Registrable Securities without Registration under the Securities Act within the limitation of the exemption provided by Rule 144 under the Securities Act, as such Rule may be amended from time to time, or any similar Rule or
regulation hereafter adopted by the Commission. 
 6. MISCELLANEOUS. 

6.1 Term. This Agreement shall terminate on the earliest to occur of (i) its termination by the consent of the parties
hereto, (ii) the date on which all of the Notes are redeemed, retired or otherwise repaid in full and (iii) the date that the Notes held by the parties hereto no longer constitute Registrable Securities. The provisions of Section 4
and Section 5 shall survive any termination. 
 6.2 Assignment; No Third Party Beneficiaries. This Agreement and the
rights, duties and obligations of the Company hereunder may not be assigned or delegated by the Company in whole or in part. This Agreement and the rights, duties and obligations of the Holders hereunder may not be assigned or delegated by the
Holders in whole or in part other than to Affiliates of the Holders in connection with a disposition of Notes in compliance with the Indenture. This Agreement and the provisions hereof shall be binding upon and shall inure to the benefit of each of
the parties. This Agreement is not intended to confer any rights or benefits on any Persons that are not party hereto other than as expressly set forth in Section 4.

 6.4 Severability. If one or more provisions of this Agreement are held to be
unenforceable under applicable law, such provision shall be deemed to be excluded from this Agreement and the balance of this Agreement shall be interpreted as if such provision were so excluded and shall be enforced in accordance with its terms to
the maximum extent permitted by law. 
 6.5 Counterparts. This Agreement may be executed in multiple counterparts, each
of which shall be deemed an original, and all of which taken together shall constitute one and the same instrument. 
 6.6
Entire Agreement. This Agreement, together with the Indenture and the Notes, constitutes the entire agreement between the parties with respect to the subject matter of this Agreement and supersedes all prior agreements and understandings,
both oral and written, between the parties and/or their affiliates with respect to the subject matter of this Agreement. 
 6.7
Modifications and Amendments. Any provision of this Agreement may be amended or modified if, but only if, such amendment or modification is in writing and is duly executed and delivered by the Company and Holders consisting of the largest
Holder Group and one additional Holder Group, provided that such Holders represent at least a majority in interest of the then outstanding Registrable Securities. 
 6.8 Waivers and Extensions. Any party to this Agreement may waive any right, breach or default which such party has the right to waive, provided that such waiver will not be effective against the
waiving party unless it is in writing, is signed by such party and specifically refers to this Agreement. No failure or delay by any party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single
or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by
law. Waivers may be made in advance or after the right waived has arisen or the breach or default waived has occurred. Any waiver may be conditional. No waiver of any breach of any agreement or provision herein contained shall be deemed a waiver of
any preceding or succeeding breach thereof nor of any other agreement or provision herein contained. No waiver or extension of time for performance of any obligations or acts shall be deemed a waiver or extension of the time for performance of any
other obligations or acts. 
 6.9 Remedies Cumulative. In the event that the Company fails to observe or perform any
covenant or agreement to be observed or performed under this Agreement, the Holders may proceed to protect and enforce their rights by suit in equity or action at law, whether for specific performance of any term contained in this Agreement or for
an injunction against the breach of any such term or in aid of the exercise of any power granted in this Agreement or to enforce any other legal or equitable right, or to take any one or more of such actions, without being required to post a bond.
None of the rights, powers or remedies conferred under this Agreement shall be mutually exclusive, and each such right, power or remedy shall be cumulative and in addition to any other right, power or remedy, whether conferred by this Agreement or
now or hereafter available at law, in equity, by statute or otherwise.
