REGISTRATION RIGHTS 

SECTION 2.1. Shelf Registration. 

(a) Preparation and Filing of Shelf Registration Statement. The Company shall (x) prepare, and, as soon as practicable file a
“shelf” registration statement with respect to the resale of the number of Registrable Securities specified by, and in accordance with the methods of distribution elected by, the Requisite Holders, on an appropriate form for the offering
and subsequent resale thereof, to be made on a delayed or continuous basis pursuant to Rule 415 under the Securities Act (the “Shelf Registration Statement”), provided that, as of the date hereof, the Company intends to file
the Shelf Registration Statement on or before October 1, 2014, and shall use its commercially reasonable efforts to cause the Shelf Registration Statement to be filed on or before the Filing Deadline, and (y) use its commercially
reasonable efforts to cause the Shelf Registration Statement to be declared effective by the SEC as promptly as reasonably practicable thereafter, but in no event later than the Effectiveness Deadline. The Company shall use its commercially
reasonable efforts to keep such Shelf Registration Statement continuously effective for a period ending when all Registrable Securities covered by the Shelf Registration Statement are no longer Registrable Securities or the date as of which each of
the Holders is permitted to sell its Registrable Securities without Registration pursuant to Rule 144 under the Securities Act without volume limitation or other restrictions on transfer thereunder. 

(b) At the time the Shelf Registration Statement is declared effective, each Holder that has delivered a duly completed and executed Notice
and Questionnaire to the Company on or prior to the date ten (10) Business Days prior to such time of effectiveness shall be named as a Selling Holder in the Shelf Registration Statement and the related prospectus in such a manner as to permit
such Holder to deliver such prospectus to purchasers of Registrable Securities in accordance with applicable law. If required by applicable law, subject to the terms and conditions hereof, after effectiveness of the Shelf Registration Statement, the
Company shall file a supplement to such prospectus or amendment to the Shelf Registration Statement not less frequently than once a quarter as necessary to name as Selling Holders therein any Holders that provide to the Company a duly completed and
executed Notice and Questionnaire and shall use commercially reasonable efforts to cause any post-effective amendment to such Shelf Registration Statement filed for such purpose to be declared effective by the SEC as promptly as reasonably
practicable after the filing thereof. 
 (c) Underwritten Shelf Registration. If the Requisite Holders so elect, by written notice to
the Company, the offering of such Registrable Securities pursuant to such Shelf Registration Statement shall be in the form of an underwritten offering; provided, that the Company shall not be obligated to effect more than three
(3) underwritten offerings under this Section 2.1(c); and provided, further, that the Company shall not be obligated to effect, or take any action to effect, an underwritten offering (i) within ninety (90) days
following the last date on which an underwritten offering was effected pursuant to this Section 2.1(c) or Section 2.2(a) or during any lock-up period required by the Underwriters in any prior underwritten offering conducted by the Company
on its own behalf, or (ii) during the period commencing with the date thirty (30) days prior to the Company’s good faith estimate of the date of filing of, and ending on a date ninety (90) days after the effective date of, a
registration statement with respect to an offering by the Company or its stockholders. The Requisite Holders shall select the Underwriter or Underwriters to serve as book-running manager or managers in connection with any such offering;
provided that such managing Underwriter or Underwriters must be reasonably satisfactory to the Company. The Company may select any additional investment banks and managers to be used in connection with the offering; provided that such
additional investment bankers and managers must be reasonably satisfactory to the Requisite Holders. 

  
 4 

 (d) Filing of Additional Registration Statements. The Company shall prepare and file such
additional registration statements as necessary every three (3) years (or such other period that may be applicable under the rules and regulations promulgated pursuant to the Securities Act) and use its commercially reasonable efforts to cause
such registration statements to be declared effective by the SEC so that the registration statement remains continuously effective with respect to resales of Registrable Securities as of and for the periods required under Section 2.1(b), such
subsequent registration statements to constitute a Shelf Registration Statement hereunder. 
 (e) Selling Holders Become Party to
Agreement. Each Holder acknowledges that by participating in its registration and cooperation rights pursuant to this Agreement, such Holder will be deemed a party to this Agreement and will be bound by its terms, notwithstanding such
Holder’s failure to deliver a Notice and Questionnaire; provided, that any Holder that has not delivered a duly completed and executed Notice and Questionnaire shall not be entitled to be named as a Selling Holder in, or have the
Registrable Securities held by it covered by, a Shelf Registration Statement. 
 SECTION 2.2. Demand Registration. 

(a) Request for Registration. In the event that the Company fails to file, has not filed or fails to maintain the effectiveness of, a
Shelf Registration Statement in accordance with Section 2.1(a) then, in addition to any other remedies the Holders may have, at law or in equity, a Requisite Holder may make a written request to the Company for registration under the Securities
Act of all or part of its Registrable Securities (a “Demand Registration”); provided, that if and so long as a Shelf Registration Statement is on file and effective with respect to the Registrable Securities, then the Company
shall have no obligation to effect a Demand Registration for such Registrable Securities. The Company shall prepare and file a registration statement on an appropriate form with respect to any Demand Registration (the “Demand Registration
Statement”) and shall use its commercially reasonable efforts to cause the Demand Registration Statement to be declared effective by the SEC as promptly as reasonably practicable after the filing thereof and the Company shall use its
commercially reasonable efforts to keep such Demand Registration Statement effective for a period ending when all Registrable Securities covered by the Demand Registration Statement are no longer Registrable Securities or the date as of which each
of the Holders is permitted to sell its Registrable Securities without Registration pursuant to Rule 144 under the Securities Act without volume limitation or other restrictions on transfer thereunder. The number of Demand Registrations which may be
made pursuant to this Section 2.2(a) shall be limited to three (3). Any request for a Demand Registration will specify the aggregate principal amount of Registrable Securities proposed to be sold and will also specify the intended method of
disposition thereof. Unless the Requisite Holders shall consent in writing, no other party shall be permitted to offer securities in connection with any such Demand Registration. Any Holder may withdraw all or any portion of its Registrable
Securities from a Demand Registration at any time prior to the effectiveness of the applicable Demand Registration Statement. Upon receipt of a notice to such effect from the applicable Holders, with respect to all of their Registrable Securities,
the Company shall cease all efforts to secure effectiveness of the applicable Demand Registration Statement. 
 (b) Effective
Registration. A registration will not count as a Demand Registration until it has become effective. 
 (c) Selling Holders Become
Party to Agreement. Each Holder acknowledges that by asserting or participating in its registration and cooperation rights pursuant to this Agreement, such Holder may become a Selling Holder and thereby will be deemed a party to this Agreement
and will be bound by each of its terms. 

  
 5 

 (d) Underwritten Demand Registrations. If the Requisite Holders so elect, by written
notice to the Company, the offering of such Registrable Securities pursuant to such Demand Registration shall be in the form of an underwritten offering. The Requisite Holders shall select the Underwriter or Underwriters to serve as book-running
manager or managers in connection with any such Demand Registration; provided that such managing Underwriter or Underwriters must be reasonably satisfactory to the Company. The Company may select any additional investment banks and managers
to be used in connection with the offering; provided that such additional investment bankers and managers must be reasonably satisfactory to the Requisite Holders. 

SECTION 2.3. Request for Offering Memorandum. 

(a) Except for Section 2.4 hereof, the Company agrees that nothing in this Agreement shall prohibit the Holders, at any time and from
time to time, from selling or otherwise transferring Registrable Securities pursuant to a private placement or other transaction which is not registered pursuant to the Securities Act. 

(b) In the event that the Company fails to file, has not filed or fails to maintain the effectiveness of, a Shelf Registration Statement in
accordance with Section 2.1(a) then, in addition to any other remedies the Requisite Holders may have, at law or in equity, the Requisite Holders may make a written request to the Company for its assistance and cooperation in conducting a
private placement of the Registrable Securities (a “Private Placement Demand”); provided, that the number of Private Placement Demands which may be made pursuant to this Section 2.3(b) shall be limited to three (3). Upon
receipt of a Private Placement Demand, the Company will enter into customary agreements (including a purchase agreement or subscription agreement, if any, in customary form) and shall use commercially reasonable efforts to take such other actions as
the Requisite Holders and initial purchasers or placement agent (as applicable, the “Selling Agent”), if any, reasonably request or that are reasonably required in order to expedite or facilitate the disposition pursuant to a
private placement of such Registrable Securities, including, without limitation, (A) the preparation of a customary offering memorandum (an “Offering Memorandum”) containing all customary information, including financial
statements (which, with respect to annual financial statements, shall have been audited and, with respect to interim financial statements, shall have been reviewed by the independent accountants for the Company as provided in Public Company
Accounting Oversight Board in AU 722), pro forma financial statements, business and other financial data of the type required in a registered offering of debt securities by Regulation S-X and Regulation S-K under the Securities Act (other than Rule
3-09, Rule 3-10 or Rule 3-16 of Regulation S-X, Rule 4.02(b) of Regulation S-K and other customary exceptions) and of the type and form that are customarily included in private placements pursuant to Rule 144A (subject to customary exceptions) and
all other financial data that would be necessary for the Selling Agent, if any, engaged for such private placement to receive customary (for similar debt securities issued in a private placement pursuant to Rule 144A) comfort letters (including
“negative assurance” comfort) from independent accountants of the Company in connection with the offering of the Registrable Securities and, in the case of the annual financial statements, the auditors’ reports thereon, together with
drafts of customary comfort letters that such accounting firms are prepared to deliver upon closing, (B) obtain for delivery to the Selling Holders and to the Selling Agent, if any, an opinion or opinions from counsel for the Company dated the
date of the closing under the purchase agreement or subscription agreement, as the case may be, in customary form, scope and substance, which opinions shall be reasonably satisfactory to such Holders or Selling Agents, as applicable, and their
respective counsel, (C) in the case of a private placement pursuant to Rule 144A, obtain for delivery to the Company and the Selling Agent, with copies to the Selling Holders, a cold comfort letter from the Company’s independent certified
public accountants in customary form and covering such matters of the type customarily covered by cold comfort letters as the Selling Agents reasonably request, dated the date of execution of the purchase agreement and brought down to the closing
under the purchase agreement and (D) taking all reasonable actions as are requested by the Selling 

  
 6 

 
Agent, or, if no Selling Agent, the Requisite Holders, to expedite or facilitate the disposition of the Registrable Securities, including causing its management to participate in a reasonable
number of customary “roadshow” or similar marketing efforts and by otherwise providing reasonable due diligence access to potential purchasers. 

SECTION 2.4. Black-Out Periods. 

(a) Notwithstanding the provisions of Sections 2.1(a), 2.1(b), 2.2(a), and 2.2(d), the Company shall be permitted to postpone the filing of
any Shelf Registration Statement filed pursuant to Section 2.1 or any registration statement filed in connection with a Demand Registration pursuant to Section 2.2 hereof, and from time to time to require the Holders not to sell
Registrable Securities under any such Shelf Registration Statement or other registration statement or to suspend the effectiveness thereof, for such times as the Company reasonably may determine is necessary and advisable, if any of the following
events shall occur (each such circumstance a “Suspension Event”): (i) a majority of the members of the board of directors of the Company determines in good faith that (A) the offer or sale of any Registrable Securities
would materially impede, delay or interfere with any proposed material financing, material acquisition, corporate reorganization or other material transaction involving the Company or (B)(x) the Company has a bona fide business purpose for
preserving the confidentiality of a material transaction that would otherwise be required to be disclosed due to such registration, (y) disclosure would have a material adverse effect on the Company or the Company’s ability to consummate
such a material transaction or (z) such a material transaction renders the Company unable to comply with Commission requirements, in each case under circumstances that would make it impractical or inadvisable, to cause the Shelf Registration
Statement or other registration statement (or such filings) to become effective or to promptly amend or supplement the Shelf Registration Statement or other registration statement on a post-effective basis, as applicable; or (ii) a majority of
the members of the board of directors of the Company determines in good faith that it is in the Company’s best interest or it is required by law, rule or regulation to supplement the Shelf Registration Statement or other registration statement
or file a post-effective amendment to such Shelf Registration Statement or other registration statement in order to ensure that the prospectus included in the Shelf Registration Statement or other registration statement (1) contains the
information required by the form on which such Shelf Registration Statement or other registration statement was filed or (2) discloses any facts or events arising after the effective date of the Shelf Registration Statement or other
registration statement (or of the most recent post-effective amendment) that, individually or in the aggregate, represents a fundamental change in the information set forth therein. Upon the occurrence of any such suspension, the Company shall use
its commercially reasonable efforts to cause the Shelf Registration Statement or other registration statement to become effective or to amend or supplement the Shelf Registration Statement or other registration statement on a post-effective basis or
to take such action as is necessary to permit resumed use of the Shelf Registration Statement or other registration statement or filing thereof as soon as reasonably possible following the conclusion of the applicable Suspension Event and its
effect. 
 The Company will provide written notice (a “Suspension Notice”) to the Holders of the occurrence of any
Suspension Event; provided, however, that the Company shall not be permitted to exercise a suspension pursuant to this Section 2.4(a)(i) more than twice during any twelve (12)-month period, or (ii) for a period exceeding
ninety (90) days on any one occasion. Upon receipt of a Suspension Notice, each Holder agrees that it will (i) immediately discontinue offers and sales of the Registrable Securities under the Shelf Registration Statement or other
registration statement and (ii) maintain the confidentiality of any information included in the Suspension Notice unless otherwise required by law or subpoena. The Holders may recommence effecting offers and sales of the Registrable Securities
pursuant to the Shelf Registration Statement or other registration statement (or such filings) following further written notice to such effect (an “End of Suspension Notice”) from the Company, which End of Suspension Notice shall be
given by the Company to the Holders promptly following the conclusion of 

  
 7 

 
any Suspension Event and its effect; provided that the Holders agree that they will only effect such offers and sales pursuant to any supplemental or amended prospectus that has been
provided to them by the Company pursuant to Section 2.4(b). 
 (b) Notwithstanding any provision herein to the contrary, if the Company
shall give a Suspension Notice with respect to any Shelf Registration Statement or other registration statement pursuant to Section 2.4(a), the Company agrees that it shall extend the period of time during which such Shelf Registration
Statement or other registration statement shall be maintained effective (including the period referred to in Section 2.5(a) hereof) by the number of days during the period from the date of receipt by the Holders of the Suspension Notice to and
including the date of receipt by the Holders of the End of Suspension Notice and promptly provide copies of the supplemented or amended prospectus necessary to resume offers and sales, with respect to each Suspension Event; provided, that
such period of time shall not be extended beyond the date that the Registrable Securities covered by such Shelf Registration Statement or other registration statement are no longer Registrable Securities. 

SECTION 2.5. Registration Procedures; Filings; Information. Subject to Section 2.4 hereof, in connection with any Shelf
Registration Statement under Section 2.1 or any Demand Registration under Section 2.2, the Company will use its commercially reasonable efforts to effect the registration and the sale of such Registrable Securities in accordance with the
intended method of disposition thereof as quickly as practicable, and in connection with any such request:

case of a Shelf Registration Statement, for the period described in Section 2.1 and (ii) in the case of a Demand Registration, for a period of not less than 270 days from the effective date of such registration statement.

subject to the review of such Selling Holder and Underwriter, if any, and their respective counsel and, the Company will not file any registration statement or amendments or supplements thereto to which the Selling Holders or the Underwriter, if

thereto and documents incorporated by reference therein), the prospectus included in such registration statement (including each preliminary prospectus) and such other documents as such Selling Holder or Underwriter may reasonably request in order
to facilitate the disposition of the Registrable Securities owned by such Selling Holders.

statement, the Company will promptly notify each Selling Holder of Registrable Securities covered by such registration statement of (i) any stop order issued or threatened by the SEC or any order by the SEC or any other regulatory authority
preventing or suspending the use of any preliminary or final prospectus or the initiation or threatening of any proceedings for such purposes, (ii) any written comments by the SEC or any request by the SEC or any other federal or state
governmental authority for amendments or supplements to such registration statement or for additional information or (iii) the receipt by the Company of any notification with respect to the suspension of the qualification of the Registrable

jurisdiction, (ii) 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 such Registrable Securities, 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, in light of the circumstances under which they were made, not misleading and promptly make available to
each Selling Holder any such supplement or amendment and (iii) deliver to each Selling Holder and each Underwriter, if any, without charge, as many copies of the applicable prospectus (including each preliminary prospectus), any amendment or
supplement thereto and such other documents useful to facilitate the disposition of the Registrable Securities as such Selling Holder or Underwriter may reasonably request. 

(g) The Company will promptly (i) incorporate in a prospectus supplement or post-effective amendment such information as the Underwriter

each Selling Holder and each Underwriter, if any, without charge, as many conformed copies as such Selling Holder or Underwriter may reasonably request of the applicable Registration Statement and any amendment or post-effective amendment thereto,
including financial statements and schedules, all documents incorporated therein by reference and all exhibits (including those incorporated by reference). 

(h) The Company will enter into customary agreements (including an underwriting agreement, if any, in customary form) and use commercially
reasonable efforts to take such other actions as the Underwriters, if any, reasonably request or that are reasonably required in order to expedite or facilitate the disposition of such Registrable Securities, including, without limitation,
(A) obtain for delivery to the Selling Holders and to the Underwriter or Underwriters, if any, an opinion or opinions from counsel for the Company dated the effective date of the applicable registration statement or, in the event of an
underwritten offering, the date of the closing under the underwriting agreement, in customary form, scope and substance, which opinions shall be reasonably satisfactory to such Holders or underwriters, as the case may be, and their respective
counsel, (B) in the case of an underwritten offering, 

  
 9 

 
obtain for delivery to the Company and the managing underwriter or underwriters, with copies to the Selling Holders, a cold comfort letter from the Company’s independent certified public

filings required to be made with FINRA. 
 (i) The Company will make available for inspection by any Selling Holder of such Registrable
Securities, if such Selling Holder has a due diligence defense under the Securities Act, any Underwriter participating in any disposition pursuant to such registration statement and any attorney, accountant or other professional retained by any such
Selling Holder or Underwriter (collectively, the “Inspectors”), all financial and other records, pertinent corporate documents and properties of the Company (collectively, the “Records”) 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 Inspector in connection with such registration statement,
subject to entry by each such Inspector into a customary confidentiality agreement in a form reasonably acceptable to the Company. 
 (j)
The Company will otherwise use its commercially reasonable efforts to comply with all applicable rules and regulations of the SEC, and make available to its securityholders, as soon as reasonably practicable, an earnings statement covering a period
of 12 months, beginning within three months after the effective date of the registration statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 of the SEC promulgated thereunder (or
any successor rule or regulation hereafter adopted by the SEC). 
 (k) The Company may require each Selling Holder of Registrable Securities
to promptly furnish in writing to the Company such information regarding such Selling Holder, the Registrable Securities held by it and the intended method of distribution of the Registrable Securities as the Company may from time to time reasonably
request and such other information as may be legally required in connection with such registration. No Holder may include Registrable Securities in any registration statement pursuant to this Agreement unless and until such Holder has furnished to
the Company such information. Each Holder further agrees to furnish as soon as reasonably practicable to the Company all information required to be disclosed in order to make information previously furnished to the Company by such Holder not
materially misleading. 
 (l) Each Selling Holder agrees that, upon receipt of any notice from the Company of the happening of any event of

receipt of written notice from the Company that such disposition may be made and, in the case of clause (ii) of Section 2.5(f) hereof, copies of the supplemented or amended prospectus contemplated by clause (ii) of Section 2.5(f)
hereof, and, if so directed by the Company, such Selling Holder will deliver to the Company all copies, other than permanent file copies then in such Selling Holder’s possession, of the most recent prospectus covering such Registrable
Securities at the time of receipt of such notice. Each Selling Holder of Registrable Securities agrees that it will promptly notify the Company at any time when a prospectus relating to the registration of such Registrable Securities is required to

fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances in which they were made. In the event the Company shall

 SECTION 2.6. Expenses. In connection with any registration statement required to be filed hereunder, the Company
shall pay the following expenses, to the extent applicable, incurred in connection with a Private Placement Demand or registration hereunder (the “Expenses”), regardless of whether such registration statement, if any, is declared

of Registrable Securities or any transfer taxes relating to the registration or sale of the Registrable Securities. 
 SECTION 2.7.

limited partner or general partner of each such member, limited or general partner, each of their respective Affiliates, officers, directors, stockholders, employees, advisors, and agents and each Person, if any, who controls such Persons within the
meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and each of their respective Representatives from and against any and all losses, penalties, judgments, suits, costs, claims, damages, liabilities and expenses
(including reasonable costs of investigation and legal expenses) (each, a “Loss”, and collectively, “Losses”) that arise out of or are based upon any untrue statement or alleged untrue statement of a material fact
contained in any registration statement, prospectus or offering memorandum relating to such Registrable Securities, or any amendment or supplement thereto, or any preliminary 

  
 11 

 
prospectus or preliminary offering memorandum, or that arise out of or are based upon any omission or alleged omission to state therein a material fact required to be stated therein or necessary
to make the statements therein, in light of the circumstances under which they were made, not misleading, except insofar as such losses, claims, damages or liabilities that arise out of or are based upon any such untrue statement or omission or
alleged untrue statement or omission with respect to information relating to such Selling Holder included in reliance upon and in conformity with information furnished in writing to the Company by such Selling Holder or on such Selling Holder’s
behalf expressly for inclusion therein. This indemnity shall be in addition to any liability the Company may otherwise have. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Selling
Holder or any Indemnified Party and shall survive the transfer of such securities by such Selling Holder. The Company also agrees to indemnify any Underwriters of, or Selling Agents for, the Registrable Securities, their officers and directors and
each Person who controls such Underwriters or Selling Agents within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and each of their respective Representatives on substantially the same basis as that of
the indemnification of the Selling Holders provided in this Section 2.7. 
 SECTION 2.8. Indemnification by Holders of Registrable
Securities. Each Selling Holder agrees, severally but not jointly, to indemnify and hold harmless the Company, its officers, directors and agents and each Person, if any, who controls the Company within the meaning of either Section 15 of
the Securities Act or Section 20 of the Exchange Act and each of their respective Representatives to the same extent as the foregoing indemnity from the Company to such Selling Holder pursuant to Section 2.7, but only with respect to
written information relating to such Selling Holder included in reliance upon and in conformity with information furnished in writing by such Selling Holder or on such Selling Holder’s behalf expressly for use in any registration statement,
prospectus or offering memorandum relating to the Registrable Securities of such Selling Holder, or any amendment or supplement thereto, or any preliminary prospectus or preliminary offering memorandum. In case any action or proceeding shall be
brought against the Company or its officers, directors or agents or any such controlling person, in respect of which indemnity may be sought against such Selling Holder, such Selling Holder shall have the rights and duties given to the Company, and
the Company or its officers, directors or agents or such controlling person shall have the rights and duties given to such Selling Holder, by Section 2.7. Each Selling Holder also agrees to indemnify and hold harmless Underwriters of, or
Selling Agents for, the Registrable Securities, their officers and directors and each Person who controls such Underwriters or Selling Agents, as applicable, within the meaning of Section 15 of the Securities Act or Section 20 of the
Exchange Act and each of their respective Representatives on substantially the same basis as that of the indemnification of the Company provided in Section 2.7. Notwithstanding the foregoing, in no event will the liability of a Selling Holder
under this Section 2.8 or Section 2.10 or otherwise hereunder exceed the net proceeds actually received by such Selling Holder. 

SECTION 2.9. Conduct of Indemnification Proceedings. In case any proceeding (including any governmental investigation) shall be
instituted involving any Person in respect of which indemnity may be sought pursuant to Section 2.7 or 2.8, such Person (an “Indemnified Party”) shall promptly notify the Person against whom such indemnity may be sought (an
“Indemnifying Party”) in writing and the Indemnifying Party shall assume the defense thereof, including the employment of counsel reasonably satisfactory to such Indemnified Party, and shall assume the payment of all fees and
expenses; provided that the failure of any Indemnified Party to give such notice will not relieve such Indemnifying Party of its obligations under Section 2.7 or 2.8, as applicable, except to the extent such Indemnifying Party is
materially prejudiced by such failure. 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 (a) the
Indemnifying Party and the Indemnified Party shall have mutually agreed to the retention of such counsel or (b) the named parties to any such proceeding (including any impleaded parties) include both the Indemnified Party and the Indemnifying
Party and representation of both parties 

  
 12 

 
by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the Indemnifying Party shall not, in connection with any proceeding
or related proceedings in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) at any time for all such Indemnified Parties, and that all such fees and
expenses shall be reimbursed as they are incurred. In the case of any such separate firm for the Indemnified Parties, such firm shall be designated in writing by (i) in the case of Persons indemnified pursuant to Section 2.7 hereof, the
Requisite Holders and (ii) in the case of Persons indemnified pursuant to Section 2.8, the Company. The Indemnifying Party shall not be liable for any settlement of any proceeding effected without its written consent, which consent shall
not be unreasonably withheld, but if settled with such consent, or if there be a final judgment for the plaintiff, the Indemnifying Party shall indemnify and hold harmless such Indemnified Parties from and against any loss or liability (to the
extent stated above) by reason of such settlement or judgment. No Indemnifying Party shall, without the prior written consent of the Indemnified Party (which consent shall not be unreasonably withheld, conditioned or delayed), effect any settlement
of any pending or threatened proceeding in respect of with any Indemnified Party is or could have been a party and indemnity could have been sought hereunder by such Indemnified Party, unless such settlement includes an unconditional release of such
Indemnified Party from all liability arising out of such proceeding without any admission of liability by such Indemnified Party. 
 SECTION
2.10. Contribution. If the indemnification provided for in Section 2.7 or 2.8 hereof is held by a court of competent jurisdiction to be unavailable to an Indemnified Party or insufficient in respect of any losses, claims, damages or
liabilities 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 losses, claims, damages or liabilities
(a) as between the Company and the Selling Holders on the one hand and the Underwriters or Selling Agents, as the case may be, on the other, in such proportion as is appropriate to reflect the relative benefits received by the Company and the
Selling Holders on the one hand and the Underwriters or Selling Agents, as the case may be, on the other from the offering of the securities, or if such allocation is not permitted by applicable law, in such proportion as is appropriate to reflect
not only the relative benefits but also the relative fault of the Company and the Selling Holders on the one hand and of the Underwriters or Selling Agents, as the case may be, on the other in connection with the statements or omissions which
resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations and (b) between the Company on the one hand and each Selling Holder on the other, in such proportion as is appropriate to reflect
the relative fault of the Company and of each Selling Holder in connection with such statements or omissions which resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits
received by the Company and the Selling Holders on the one hand and the Underwriters or Selling Agents, as the case may be, on the other shall be deemed to be in the same proportion as the total proceeds from the offering (net of underwriting or
initial purchaser discounts, as applicable, and commissions but before deducting expenses) received by the Company and the Selling Holders bear to the total underwriting or initial purchaser discounts, as applicable, and commissions received by the
Underwriters or Selling Agents, as the case may be, in each case as set forth on the cover page of the prospectus or the Offering Memorandum, as applicable. The relative fault of the Company and the Selling Holders on the one hand and of the
Underwriters or Selling Agents, as the case may be, on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company and the Selling Holders or by the Underwriters or Selling Agents, as the case may be. The relative fault of the Company on the one hand and of each Selling Holder on the other 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 party, and the parties’ relative intent,
knowledge, access to information and opportunity to correct or prevent such statement or omission. 

  
 13 

 The Company and the Selling Holders agree that it would not be just and equitable if contribution
pursuant to this Section 2.10 were determined by pro rata allocation (even if the Underwriters or Selling Agents, as the case may be, were treated as one entity for such purpose) or by any other method of allocation which does not take
account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an Indemnified Party as a result of the losses, claims, damages or liabilities referred to in the immediately preceding
paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending any such action or claim. Notwithstanding the
provisions of this Section 2.10, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the 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 Selling Agent shall be required to contribute any amount in excess
of the amount by which the total price at which the securities initially purchased by it were resold pursuant to a private placement exceeds the amount of any damages which such Selling Agent has otherwise been required to pay by reason of such
untrue or alleged untrue statement or omission or alleged omission, and no Selling Holder shall be required to contribute any amount in excess of the amount by which the total price at which the securities of such Selling Holder were offered to the
public or resold pursuant to a private placement exceeds the amount of any damages which such Selling Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No Person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. The Selling Holder’s obligations to
contribute pursuant to this Section 2.10 are several in such proportion that the proceeds of the offering received by such Selling Holder bears to the total proceeds of the offering received by all the Selling Holders, and not joint. 

SECTION 2.11. Participation in Underwritten or 144A Offerings. No Person may participate in any underwritten offering or private
placement pursuant to 144A hereunder unless such Person (a) agrees to sell such Person’s securities on the basis provided in any underwriting or initial purchasing arrangements approved by the Persons entitled hereunder to approve such
arrangements and (b) completes and executes all customary questionnaires, powers of attorney, indemnities, underwriting agreements or purchase agreements and other documents reasonably required under the terms of such customary arrangements and
the registration and cooperation rights provided for in this Article II. 
 SECTION 2.12. Rule 144. The Company covenants that it
will timely file any reports required to be filed by it under the Securities Act and the Exchange Act and that it will take such further action as any Holder may reasonably request, all to the extent required from time to time to enable Holders to
sell Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by Rule 144. Upon the reasonable request of any Holder, the Company will deliver to such Holder a written statement as to
whether it has complied with such requirements and, if not, the specific thereof. 
 SECTION 2.13. Holdback Agreements. 

(a) Restrictions on Public Sale by the Company and Others. The Company agrees that any agreement entered into after the date of this
Agreement pursuant to which the Company issues or agrees to issue any privately placed securities shall contain a provision under which holders of such securities agree not to effect any sale or distribution of the same class as any securities as
those being sold in connection with an underwritten public offering in accordance with Section 2.1 or 2.2 hereof, or any securities convertible into or exchangeable or exercisable for such securities, during the seven (7) days prior to,
and during the 90-day period beginning on, the pricing date of such underwritten public offering, 

  
 14 

 
if and to the extent requested in writing by the managing Underwriter or Underwriters (such agreement to be in the form of lock-up agreement provided by the managing Underwriter or Underwriters),
in each case including a sale pursuant to Rule 144 (except as part of any such registration, if permitted); provided, however, that the provisions of this paragraph (b) shall not prevent the conversion or exchange of any
securities pursuant to their terms into or for other securities. 
 ARTICLE III 

MISCELLANEOUS 
 SECTION
3.1. Remedies. In addition to being entitled to exercise all rights provided herein and granted by law, including recovery of damages, the Holders shall be entitled to specific performance of the rights under this Agreement. The Company
agrees that monetary damages would not be adequate compensation for any loss incurred by reason of a breach by it of the provisions of this Agreement and hereby agrees to waive the defense in any action for specific performance that a remedy at law
would be adequate. Notwithstanding the foregoing, specific performance shall not be available with respect to the rights and obligations of the parties pursuant to Section 2.13(a). 

SECTION 3.2. Amendments and Waivers. The provisions of this Agreement, including the provisions of this sentence, may not be amended,
modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given, in each case without the written consent of the Company and the Requisite Holders. No failure or delay by any party to insist upon the
strict performance of any covenant, duty, agreement or condition of this Agreement or to exercise any right or remedy consequent upon any breach thereof shall constitute waiver of any such breach or any other covenant, duty, agreement or condition.

delivery, registered first-class mail, telecopier, or air courier guaranteeing overnight delivery:

by addressee or receipt is otherwise confirmed, if by electronic mail. 
 SECTION 3.4. Successors and Assigns. Except as expressly
provided in this Agreement, the rights and obligations of the Holders under this Agreement shall not be assignable by any Holder to any Person that is not a Holder. This Agreement shall be binding upon the parties hereto and their respective
successors and assigns.

hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. Each party shall become bound by this Agreement immediately upon affixing
its signature hereto.

accordance with the internal laws of the State of Delaware without regard to the choice of law provisions thereof.

Severability. In the event that any one or more of the provisions contained herein, or the application thereof in any circumstance, is held invalid, illegal or unenforceable, the validity, legality and enforceability of any such provision in

 EXHIBIT A 

CAESARS ENTERTAINMENT OPERATING COMPANY, INC. 

FORM OF NOTICE AND QUESTIONNAIRE 

The undersigned beneficial holder of 6.50% Senior Notes and/or 5.75% Senior Notes of Caesars Entertainment Operating Company, Inc. (the
“Company”), understands that the Company has filed or intends to file with the Securities and Exchange Commission (the “SEC”) one or more registration statements (collectively, the “Shelf Registration
Statement”) for the registration and resale under Rule 415 of the Securities Act of 1933, as amended (the “Securities Act”), of the Registrable Securities in accordance with the terms of the Registration Rights and
Cooperation Agreement, dated                      , 2014 (the “Registration Rights and Cooperation Agreement”), among the Company
and the holders party thereto. A copy of the Registration Rights and Cooperation Agreement is available from the Company upon request at the address set forth below. All capitalized terms not otherwise defined herein shall have the meanings ascribed
thereto in the Registration Rights and Cooperation Agreement. 
 Each beneficial owner of Registrable Securities is entitled to the
benefits of the Registration Rights and Cooperation Agreement. In order to sell or otherwise dispose of any Registrable Securities pursuant to the Shelf Registration Statement, a beneficial owner of Registrable Securities generally will be required
to be named as a selling security holder in the related prospectus, deliver a prospectus to purchasers of Registrable Securities and be bound by those provisions of the Registration Rights and Cooperation Agreement applicable to such beneficial
owner (including certain indemnification provisions as described below). To be included in the Shelf Registration Statement, this Notice and Questionnaire must be completed, executed and delivered to the Company at the address set forth herein on
or prior to the tenth business day before the effectiveness of the Shelf Registration Statement. We will give notice of the filing and effectiveness of the initial Shelf Registration Statement by mailing a notice to the holders at their
addresses set forth in the register of the registrar.  
 Beneficial owners that do not complete this Notice and Questionnaire and
deliver it to the Company as provided below will not be named as selling security holders in the prospectus and therefore will not be permitted to sell any Registrable Securities pursuant to the Shelf Registration Statement. Beneficial owners are
encouraged to complete and deliver this Notice and Questionnaire prior to the effectiveness of the initial Shelf Registration Statement so that such beneficial owners may be named as selling security holders in the related prospectus at the time of
effectiveness. Upon receipt of a completed Notice and Questionnaire from a beneficial owner following the effectiveness of the initial Shelf Registration Statement, in accordance with the Registration Rights and Cooperation Agreement, the Company
will file such amendments to the initial Shelf Registration Statement or additional shelf registration statements or supplements to the related prospectus as are necessary to permit such holder to deliver such prospectus to purchasers of Registrable
Securities. 
 Certain legal consequences arise from being named as selling security holders in the Shelf Registration Statement and the
related prospectus. Accordingly, holders and beneficial owners of Registrable Securities are advised to consult their own securities law counsel regarding the consequences of being named or not being named as a selling security holder in the Shelf
Registration Statement and the related prospectus. 

 NOTICE 

The undersigned beneficial owner (the “Selling Security Holder”) of Registrable Securities hereby elects to include in the
prospectus forming a part of the Shelf Registration Statement the Registrable Securities beneficially owned by it and listed below in Item 3 (unless otherwise specified under Item 3). The undersigned, by signing and returning this Notice
and Questionnaire, understands that it will be bound by the terms and conditions of this Notice and Questionnaire and the Registration Rights and Cooperation Agreement.

directors, officers and each person, if any, who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against certain losses arising in connection with statements
