million; provided, further, that the Registration Statement effecting such IPO Demand Registration shall not be required to become effective until April 1, 2013. The IPO Requesting

Offering, any Demand Holders or Second Demand Holder (in such capacity, the “Requesting Holder”) may request registration under the Securities Act of all or any portion of the Registrable Securities held by such Requesting
Holder on Form S-1 or similar long-form registration (a “Long-Form Registration”) with respect to up to one Long-Form Registration per annum (provided that any Second Demand Holder may request up to two Long-Form

discounts) is reasonably expected to exceed, in the aggregate, $100 million. 
 (b) Demand Registration Notices. All
requests for Demand Registrations (including the IPO Demand Registration) shall be made by giving written notice to the Company (the “Demand Registration Notice”). Each Demand Registration Notice shall specify
(i) whether such Demand Registration shall be an underwritten offering, (ii) the approximate number of Registrable Securities proposed to be sold in the Demand Registration and (iii) the expected price range (net of underwriting
discounts and commissions) of such Demand Registration. Within five Business Days after receipt of any Demand Registration Notice, the Company shall give written notice of such requested Demand Registration to all other Holders of Registrable
Securities (the “Company Demand Registration Notice”) and, subject to the provisions of Section 2(e) below, shall include in such Demand Registration all Registrable Securities with respect to which the Company
has received written requests for inclusion therein within 10 Business Days after delivery of the Company Demand Registration Notice. 
 (c) Long-Form Registrations. A registration shall not count as one of the permitted Long-Form Registrations until both (i) it has become effective (unless such Long-Form Registration has not
become effective due solely to the fault of the Demand Holders or Second Demand Holder requesting such registration) and (ii) the Demand Holders or Second Demand Holder initially requesting such registration is able to register and sell
pursuant to such registration at least 90% of the Registrable Securities requested to be included in such registration either at the time of the registration or within 90 days thereafter; provided that a Long-Form Registration which is
withdrawn at the sole request of the Demand Holders or Second Demand Holder who demanded such Long-Form Registration will count as a Long-Form Registration unless the Company is reimbursed by such Demand Holders or Second Demand Holder for all
reasonable out-of-pocket expenses incurred by the Company in connection with such registration, including reasonable attorney and accounting fees. 
 (d) Short-Form Registrations. Demand Registrations shall be Short Form Registrations whenever the Company is permitted to use an applicable short form. Promptly

  
 9 

 
after the Company has become subject to the reporting requirements of the Exchange Act, the Company shall use its commercially reasonable efforts to make Short-Form Registrations on Form S-3 (or
any successor form) available for the sale of Registrable Securities. 
 (e) Priority on Demand Registrations. If the
Demand Registration is an underwritten offering and the managing underwriters for such Demand Registration advise the Company and the applicable Requesting Holders that the number of Registrable Securities and, if permitted hereunder, other
securities requested to be included in such Demand Registration exceeds the number of Registrable Securities and other securities, if any, which can be sold in an orderly manner in such offering within a price range acceptable to the Holders of a
majority of the Registrable Securities requested to be included in the Demand Registration, the Company shall include in such Demand Registration the number of Registrable Securities which can be so sold in the following order of priority:
(i) first, the First Priority Registrable Securities requested to be included in such Demand Registration by the 5% Requesting Holders, pro rata among such 5% Requesting Holders holding First Priority Registrable Securities on the
basis of the total number of shares of Common Stock owned by each such 5% Requesting Holder immediately prior to such offering; (ii) second, all Registrable Securities of all other Holders requested to be included in such Demand
Registration and all Second Priority Registrable Securities requested to be included in such Demand Registration by the 5% Requesting Holders, pro rata among all such Holders on the basis of the number of shares of Common Stock owned by each
such Holder after taking into account sales in the offering of the First Priority Registrable Securities; and (iii) third, the securities the Company proposes to sell; provided however that, with respect to the IPO Demand
Registration only as to which Section 3 does not apply, the order of priority shall be as follows: (x) first, the Registrable Securities requested to be included in such Demand Registration by the Requesting Holders and the
other Registrable Securities requested to be included in such Demand Registration by Holders, which in the judgment of such underwriter can be sold in an orderly manner within the price range of such offering, pro rata among all such Holders
of such Registrable Securities on the basis of the number of Registrable Securities requested to be included therein by each such Holder; and (y) second, the securities the Company proposes to sell. 

(f) Restrictions on Demand Registrations. The Company shall not be obligated to effect (i) any Long-Form Registration within
180 days or (ii) any Short-Form Registration within 120 days, in each case, after the effective date of a previous Demand Registration or a previous registration in which the Holders of Registrable Securities were given piggyback rights
pursuant to Section 7 and in which such Holders were able to register and sell at least 90% of the number of Registrable Securities requested to be included therein. In addition, the Company shall not be obligated to effect any Demand
Registration during the period starting with the date that is 60 days prior to the Board’s good faith estimate of the date of filing of, and ending on the date that is 120 days (unless the underwriting agreement requires a longer period of
time) after the effective date of, a Company initiated registration statement, provided that the Company is actively employing in good faith all commercially reasonable efforts to cause such registration to become effective, and
provided further that the aggregate number of days that any one or more Demand Registrations are suspended or delayed by operation of this Section 2(f) shall not exceed 120 days in any 12-month period. In the event of any
such suspension or delay, the Holder of Registrable Securities initially requesting a Demand Registration that is suspended by operation of this Section 2(f) shall be entitled to withdraw such

  
 10 

 
request and, if such request is withdrawn, such Demand Registration shall not count as one of the permitted Demand Registrations hereunder, and, notwithstanding the proviso in
Section 2(c), the Company shall pay all Registration Expenses in connection with such registration. 
 (g)
Selection of Underwriters. The Holders of a majority of the Registrable Securities requested to be included in a Demand Registration which is an underwritten offering shall have the right to select the investment banker(s) and manager(s) to
administer the offering (which shall consist of one or more reputable nationally recognized investment banks), subject to the Company’s approval which shall not be unreasonably withheld, conditioned or delayed. 

(h) Transfer of Demand Rights. The rights of a Holder under this Section 2 may be transferred, assigned or otherwise
conveyed in whole or in part, to any transferee or assignee, provided that the requirements of Section 20 are satisfied. 
 3. IPO Drag-Along Rights. 
 (a) At any time after January 1, 2013, in
connection with an exercise of the IPO Demand Registration, the IPO Requesting Holders may deliver a notice to the Company (the “Requested IPO Drag-Along Sale Notice”) of the IPO Requesting Holders’ intention to sell
Registrable Securities in an Initial Public Offering and invoking the provisions of this Section 3; provided, that the offering price of the Registrable Securities in such Initial Public Offering must equate to a total equity
value of the Company of not less than $1.5 billion (an “IPO Drag-Along Sale”). Any Requested IPO Drag-Along Sale Notice shall identify the maximum amount of Registrable Securities required to be sold in such Initial Public
Offering by each Holder, which maximum amount shall not exceed 15% of the Common Stock held by each Holder and required to be sold (inclusive of shares subject to a customary overallotment option granted to the underwriters), subject to
Section 3(c) and subject to any adjustment to be implemented pursuant to Section 4, which adjustment shall not increase such percentage above 15% (in each case, inclusive of shares subject to a customary over-allotment option
granted to the underwriters) (the “IPO Drag-Along Percentage”). Any Requested IPO Drag-Along Sale Notice shall terminate and be of no further force and effect if the offering price of the Registrable Securities in such IPO
Drag-Along Sale does not equate to a total equity value of the Company of at least $1.5 billion. Any Requested IPO Drag-Along Sale Notice shall be irrevocable once delivered to the Company. 

(b) If the IPO Requesting Holders deliver the IPO Drag-Along Sale Notice, each Holder including, for avoidance of doubt, each of the IPO
Requesting Holders, but expressly excluding any employee of the Company who is employed by the Company on the date of the Requested IPO Drag-Along Sale Notice (each Holder, a “IPO Dragged Holder”) shall (A) sell in the
Initial Public Offering Registrable Securities equal to (subject to increase or reduction as provided in Section 3(c) and subject to exercise of the over-allotment option) (i) the IPO Drag-Along Percentage times (ii) the number
of Registrable Securities held by such Holder, in each case at the price determined pursuant to Section 4 and in accordance with other provisions of this Section 3; and (B) otherwise take all other actions reasonably
necessary or desirable to consummate the IPO Drag-Along Sale and the Initial Public Offering; provided that this clause (B) shall not obligate any IPO Dragged Holder to enter into any lockup or restriction on Transfers other than as
specifically provided in this Agreement or incur costs or liabilities 

  
 11 

 
other than as specifically provided in this Agreement, including Section 13 and Section 14. The Company shall provide notice of an IPO Drag-Along Sale to each IPO Dragged
Holder (a “IPO Drag-Along Sale Notice”) not later than ten (10) Business Days prior to the scheduled launch of marketing of the proposed Initial Public Offering. The IPO Drag-Along Sale Notice shall (i) identify the
IPO Drag-Along Percentage, (ii) notify the IPO Dragged Holders (x) of any Required Information that such IPO Dragged Holder is required to provide in connection with the IPO Drag-Along Sale and (y) that, subject to
Section 3(c), each IPO Dragged Holder may sell in the Initial Public Offering a number of Registrable Securities which represents a percentage of the Registrable Securities held by such IPO Dragged Holder that is (i) equal to the
IPO Drag-Along Percentage and an additional number that is greater than the IPO Drag-Along Percentage (any such Registrable Securities pursuant to this clause (i) in addition to the IPO Drag-Along Percentage, “Incremental
Shares”), (ii) equal to the IPO Drag-Along Percentage without any reduction to such sales resulting from sales by other IPO Dragged Holders or (iii) equal to the Diluted IPO Drag-Along Percentage, in each case at the same
price as the price in the IPO Drag-Along Sale. Each IPO Dragged Holder shall be required to participate in the IPO Drag-Along Sale on the terms and conditions set forth in the IPO Drag-Along Sale Notice, so long as the offering price of the
Registrable Securities in such IPO Drag-Along Sale equates to a total equity value of the Company of not less than $1.5 billion, on the terms and conditions set forth in the IPO Drag-Along Sale Notice. 

(c) Each IPO Dragged Holder shall provide notice to the Company (an “Incremental Share Notice”) not later than
seven (7) Business Days after receipt of the IPO Drag-Along Sale Notice, which notice shall specify one (but only one) of the following three options with respect to such IPO Dragged Holder’s Registrable Securities: (x) such IPO
Dragged Holder desires to sell the IPO Drag-Along Percentage and a greater fixed percentage of its Registrable Securities above the IPO Drag-Along Percentage (and specify the percentage desired to be sold), (y) such IPO Dragged Holder desires
to sell the IPO Drag-Along Percentage of its Registrable Securities without any reduction to such sales resulting from sales by other IPO Dragged Holders or (z) such IPO Dragged Holder is willing to have the Registrable Securities sold by it
reduced (down to zero, if applicable) by the sales of Incremental Shares being sold in the Initial Public Offering (such Registrable Securities, the “IPO Drag-Along Shares”). The Registrable Securities to be sold in the
Initial Public Offering shall be sold as follows: (i) first, all of the Registrable Securities requested to be sold pursuant to clause (y) of the preceding sentence and the IPO Drag-Along Percentage of the Registrable Securities held by
Holders that elected to sell Incremental Shares pursuant to clause (x) of the preceding sentence; (ii) second, all of the Incremental Shares requested to be sold pursuant to the Incremental Share Notices in excess of those to be sold
pursuant to clause (i); and (iii) third, the percentage of Registrable Securities to be sold by the remaining IPO Dragged Holders (such percentage, the “Diluted Drag-Along Percentage”), which shall be determined by
deducting the number of the Registrable Securities sold pursuant to clauses first and second above from the IPO Sale Amount, applying such reduction pro rata to the IPO Drag-Along Percentage for the Registrable Securities of the remaining IPO
Dragged Holders subject to the IPO Drag-Along Notice and then selling the Registrable Securities (if any) subject to such Diluted IPO Drag-Along Percentage. For the avoidance of doubt, whether or not an IPO Dragged Holder elects to give an
Incremental Share Notice or sells any Incremental Shares, such IPO Dragged Holder shall nonetheless be obligated to sell the percentage of such Holder’s Registrable Securities pursuant to the IPO Drag-Along Sale as set forth in
Section 3(b) (as reduced, to the extent applicable, by the immediately 

  
 12 

 
preceding sentence). If an IPO Dragged Holder does not give a notice pursuant to this Section 3(c), then such IPO Dragged Holder shall be deemed to have requested to sell Registrable
Securities pursuant to clause (y) of the first sentence of this Section 3(c). 
 (d) If the managing
underwriters for such IPO Drag-Along Sale advise the Company and the IPO Dragged Holders that the number of Registrable Securities and, if permitted hereunder, other securities requested to be included in such IPO Drag-Along Sale exceeds the number
of Registrable Securities and other securities, if any, which can be sold in an orderly manner in such offering within a price range required pursuant to Section 3, the Company shall include in such IPO Drag-Along Sale the number of
Registrable Securities which can be so sold in the following order of priority: (i) first, the Registrable Securities requested to be included in such IPO Drag-Along Sale in clause (y) of the first sentence of Section 3(c) and
the IPO Drag-Along Percentage of the Registrable Securities held by Holders that elected to sell Incremental Shares pursuant to clause (x) of the first sentence of Section 3(c), (ii) second, the Incremental Shares requested to
be included in such IPO Drag-Along Sale in clause (x) of the first sentence of Section 3(c), pro rata among the respective IPO Dragged Holders of such Incremental Shares on the basis of the number of Registrable Securities requested
to be included therein by each such IPO Dragged Holder, (iii) third, the securities the Company proposes to sell, if any third and (iv) fourth, the Registrable Securities requested to be included in such IPO Drag-Along Sale in clause
(z) of the first sentence of Section 3(c), pro rata among the respective IPO Dragged Holders of such Registrable Securities on the basis of the number of Registrable Securities requested to be included therein by each such IPO
Dragged Holder. 
 (e) Each IPO Dragged Holder shall deliver, within three (3) Business Days after receipt of the IPO
Drag-Along Sale Notice, the Required Information with respect to such IPO Dragged Holder. 
 (f) If the offering price of the
Registrable Securities in such IPO Drag-Along Sale does not equate to a total equity value of the Company of at least $1.5 billion, the Company shall return to each of the IPO Dragged Holders the limited power-of-attorney and all certificates, if
any, that such IPO Dragged Holders have delivered for transfer pursuant hereto, together with any other documents in the possession of the Company executed by the IPO Dragged Holders in connection with the proposed IPO Drag-Along Sale. Subject to
compliance with the immediately preceding sentence, neither the Company (or its managers or officers) nor any IPO Requesting Holder shall have any liability to any Holder if an IPO Drag-Along Sale or an Initial Public Offering is not consummated for
any reason. 
 (g) The provisions of this Section 3 shall not be deemed to impose any restrictions on transfer until
the date that is seven days prior to the pricing of the proposed Initial Public Offering and any such restrictions shall terminate if the Initial Public Offering is not consummated. 

(h) The Company and the IPO Dragged Holders agree that no IPO Dragged Holder (including any IPO Requesting Holder) that complies with the
provisions of this Section 3 shall be required to pay any underwriting spread to any underwriter in the Initial Public Offering implemented pursuant to the IPO Drag-Along Sale and that the Company will pay such underwriters a commission
in lieu of such underwriting spread in connection with the Initial Public Offering implemented pursuant to the IPO Drag-Along Sale. 

  
 13 

 (i) In the event that an over-allotment option is granted to the underwriters of an Initial
Public Offering and such over-allotment option expires and has not been exercised in full in accordance with its terms or less than all the IPO Drag-Along Shares or Incremental Shares are sold in an Initial Public Offering as a result of
Section 3(c), the Company shall be obligated to promptly return to each of the IPO Dragged Holders all certificates, if any, representing such Registrable Securities and any applicable transfer instruments in respect thereof that such
IPO Dragged Holders have delivered for transfer pursuant hereto with respect to the portion of such IPO Dragged Holder’s IPO Drag-Along Shares or Incremental Shares that remain unsold as a result thereof. 

4. Drag Adjustments and Pricing. Each of (i) the sale price for the Registrable Securities to be offered in connection with
the Initial Public Offering implemented pursuant to the IPO Drag-Along Sale, (ii) the selection of investment banker(s) and manager(s) to administer the offering (which shall consist of one or more reputable nationally recognized investment
banks) and (iii) any revision to the IPO Drag-Along Percentage from the amount specified in the Requested IPO Drag-Along Sale Notice, which revision may not cause the IPO Drag-Along Percentage to exceed 15% of the Common Stock held by each
Holder (inclusive of shares subject to a customary overallotment option granted to the underwriters), shall be determined by the Board. 
 5. Power of Attorney. 
 (a) In order to enforce Section 3 and
Section 4, each Holder hereby grants this irrevocable power of attorney to the Company to sell the IPO Dragged Holder’s IPO Drag-Along Shares in accordance with the terms of this Agreement in the event that such IPO Dragged Holder
fails to act in accordance with its obligations pursuant to Section 3 and Section 4. 
 (b) In connection with the
foregoing, each undersigned Holder hereby irrevocably appoints the Company or its substitute under Section 5(e), with full power of substitution, the attorney-in-fact (the “Attorney-in-Fact”) of the undersigned,
and agrees that the Attorney-in-Fact may also act as attorney-in-fact for other IPO Dragged Holders, with full power and authority in the name of, and for and on behalf of, the undersigned: 

(i) to do all things necessary, subject to the terms of this Agreement, to sell to the underwriters up to the IPO Drag-Along Shares;

 (ii) for the purpose of effecting such sale, to negotiate, execute, deliver and perform the undersigned’s obligations
under an underwriting agreement (the “Underwriting Agreement”) among the Company, the IPO Dragged Holders and representatives of the several underwriters, subject to the terms of this Agreement, including but not limited to
Section 14, as may be approved in the sole discretion of the Attorney-in-Fact, such approval to be conclusively evidenced by the execution and delivery of the Underwriting Agreement by the Attorney-in-Fact; 

(iii) for the purpose of effecting such sale, to negotiate, execute, deliver and perform the undersigned’s obligations under a

will hold such IPO Drag-Along Shares, as custodian (the “Custodian”) under the Custody Agreement, as may be approved in the sole discretion of the Attorney-in-Fact, such approval to be conclusively evidenced by the execution
and delivery of the Custody Agreement by the Attorney-in-Fact; 
 (iv) subject to the terms of this Agreement, to execute and
deliver any amendments, modifications or supplements to the Underwriting Agreement and the Custody Agreement or to amend, modify or supplement any of the terms thereof including, without limitation, the terms of the offering; provided, however that

 (v) subject to the terms of this Agreement, to give such orders and instructions to the Custodian or any other person as the Attorney-in-Fact may determine, including, without limitation, orders or

at any subsequent time of delivery; 
 (vi) subject to the terms of this Agreement, to arrange for, prepare or cause to be

sales of the IPO Drag-Along Shares; and to join the Company in withdrawing the Registration Statement if the Company should desire to withdraw such registration; 

  
 15 

 (vii) to retain legal counsel in connection with any and all matters referred to herein
(which counsel may, but need not be, counsel for the Company); 
 (viii) subject to the terms of this Agreement, to agree upon
the allocation and to arrange payment therefor of the expenses of the Initial Public Offering (including, without limitation, the fees and expenses of the Custodian and the fees and expenses of counsel referred to above) between and among the
Company and the IPO Dragged Holders, including the undersigned; 
 (ix) to endorse (in blank or otherwise) on behalf of the
undersigned a stock power or powers; and 
 (x) subject to the terms of this Agreement, to make, execute, acknowledge and
deliver all other contracts, orders, receipts, notices, requests, instructions, certificates, letters and other writings, including communications to the Commission (including a request or requests for acceleration of the effective date of the
Registration Statement) and state securities law authorities, any amendments to the Underwriting Agreement, the Custody Agreement or any agreement with the Company with regard to expenses, and certificates and other documents required to be
delivered by or on behalf of the undersigned pursuant to the Underwriting Agreement or the Custody Agreement, and specifically to execute on behalf of the undersigned stock powers and transfer instructions relating to the IPO Drag-Along Shares to be
sold by the undersigned, and in general to do all things and to take all action which the Attorney-in-Fact may consider necessary or proper in connection with, or to carry out and comply with, all terms and conditions of the Underwriting Agreement
and the Custody Agreement and the aforesaid sale of IPO Drag-Along Shares to the Underwriters. 
 (c) For the avoidance of
doubt, this Section 5 does not confer any authority to the Attorney-in-Fact (i) to waive, amend or modify any rights or benefits granted to any Holder pursuant to the terms of this Agreement or any other term of this Agreement or
(ii) to take any action inconsistent with any such rights or benefits. 
 (d) This Power of Attorney and all authority
conferred hereby are granted and conferred subject to the interests of the Underwriters and the other IPO Dragged Holders; and, in consideration of those interests and for the purpose of completing the transactions contemplated by the Underwriting
Agreement and this Power of Attorney, this Power of Attorney and all authority conferred hereby, to the extent enforceable by law, shall be deemed an agency coupled with an interest and be irrevocable and not subject to termination by the
undersigned or by operation of law, whether by the death or incapacity of the undersigned or any executor or trustee or the termination of any estate or trust or by the dissolution or liquidation of any entity or by the occurrence of any other
event, and the obligations of the undersigned under the Underwriting Agreement similarly are not to be subject to termination. If any such individual or any such executor or trustee should die or become incapacitated or if any such estate or trust
should be terminated or if any such entity should be dissolved or liquidated or if any other such event should occur before the delivery of the IPO Drag-Along Shares to be sold by the undersigned under the Underwriting Agreement, the IPO Drag-Along
Shares shall be delivered by or on behalf of the undersigned in accordance with the terms and conditions of the Underwriting Agreement and the Custody Agreement and all other actions required to be taken

  
 16 

 
under the Underwriting Agreement or the Custody Agreement shall be taken, and actions taken by the Attorney-in-Fact pursuant to this Power of Attorney and by the Custodian under the Custody
Agreement shall be as valid as if such death, incapacity, termination, dissolution, liquidation or other event had not occurred, regardless of whether or not the Custodian or the Attorney-in-Fact shall have received notice of such death, incapacity,
termination, dissolution, liquidation or other event. 
 (e) The undersigned ratifies that the Attorney-in-Fact shall have full
power to make and substitute any person in the place and stead of the Attorney-in-Fact, and hereby ratifies and confirms all that each Attorney-in-Fact or substitute or substitutes shall do by virtue of these presents. 

(f) The Attorney-in-Fact shall be entitled to act and rely upon any statement, request, notice or instructions respecting this Power of
Attorney given to it by the undersigned, not only as to the authorization, validity and effectiveness thereof, but also as to the truth and acceptability of any information therein contained. 

6. Shelf Registrations. 
 (a) Filing. As soon as the Company is required to file reports under Section 13 or Section 15(d) of the Exchange Act, the Company shall commence using its commercially reasonable efforts
to file a Registration Statement for a Shelf Registration on Form S-1 covering the resale of the Registrable Securities on a delayed or continuous basis (the “Form S-1 Shelf”). The Company shall use commercially reasonable
efforts to cause the Form S-1 Shelf to become effective as soon as practicable after such filing. The Company shall give written notice of the filing of the Registration Statement at least 15 days prior to filing the Registration Statement to all
Holders of Registrable Securities (the “Registration Notice”) and shall include in such Registration Statement all Registrable Securities with respect to which the Company has received written requests for inclusion therein
within 20 days after delivery of the Registration Notice. The Company shall maintain the Shelf in accordance with the terms hereof. The Company shall use its commercially reasonable efforts to convert the Form S-1 Shelf (and any Follow-On Shelf) to
a Registration Statement for a Shelf Registration on Form S-3 (the “Form S-3 Shelf,” and together with the Form S-1 Shelf (and any Follow-On Shelf), the “Shelf”) as soon as practicable after the
Company is eligible to use Form S-3. 
 (b) Requests for Underwritten Shelf Takedowns. At any time and from time to time
after the Shelf has been declared effective by the Commission, any Demand Holder or Second Demand Holder may request to sell all or any portion of their Registrable Securities in an underwritten offering that is registered pursuant to the Shelf
(each, an “Underwritten Shelf Takedown”); provided that in the case of each such Underwritten Shelf Takedown such Demand Holders or Second Demand Holder will be entitled to make such demand only if the total offering
price of the Registrable Securities to be sold in such offering (including piggyback shares and before deduction of underwriting discounts) is reasonably expected to exceed, in the aggregate, $100 million. 

(c) Demand Notices. All requests for Underwritten Shelf Takedowns shall be made by giving written notice to the Company (the
“Demand Shelf Takedown Notice”). Each 

  
 17 

 
Demand Shelf Takedown Notice shall specify the approximate number of Registrable Securities proposed to be sold in the Underwritten Shelf Takedown and the expected price range of such
Underwritten Shelf Takedown. Within five Business Days after receipt of any Demand Shelf Takedown Notice, the Company shall give written notice of such requested Underwritten Shelf Takedown to all other Holders of Registrable Securities (the
“Company Shelf Takedown Notice”) and, subject to the provisions of Section 6(d), shall include in such Underwritten Shelf Takedown all Registrable Securities with respect to which the Company has received written
requests for inclusion therein within 10 Business Days after sending the Company Shelf Takedown Notice. 
 (d) Priority on
Underwritten Shelf Takedowns. If the managing underwriters for such Underwritten Shelf Takedown advise the Company that the number of Registrable Securities and, if permitted hereunder, other securities requested to be included in such
Underwritten Shelf Takedown exceeds the number of Registrable Securities and other securities, if any, which can be sold in an orderly manner in such offering within a price range acceptable to the Holders of a majority of the Registrable Securities
requested to be included in the Underwritten Shelf Takedown, the Company shall include in such Underwritten Shelf Takedown the number of Registrable Securities which can be so sold in the following order of priority: (i) first, the First
Priority Registrable Securities requested to be included in such Underwritten Shelf Takedown by the 5% Requesting Holders, pro rata among such 5% Requesting Holders holding First Priority Registrable Securities on the basis of the total
number of shares of Common Stock owned by each such 5% Requesting Holder immediately prior to such offering; (ii) second, all Registrable Securities of all other Holders requested to be included in such Underwritten Shelf Takedown and
all Second Priority Registrable Securities requested to be included in such Underwritten Shelf Takedown by the 5% Requesting Holders, pro rata among all such Holders on the basis of the number of shares of Common Stock owned by each such Holder
after taking into account sales in the offering of the First Priority Registrable Securities; and (iii) third, the securities the Company proposes to sell. 
 (e) Restrictions on Underwritten Shelf Takedowns. The Company shall not be obligated to effect more than three Underwritten Shelf Takedowns during any period of 12 consecutive months and shall not
be obligated to effect an Underwritten Shelf Takedown within 90 days after the pricing of a previous Underwritten Shelf Takedown. 
 (f) Selection of Underwriters. The Holders of a majority of the Registrable Securities requested to be included in an Underwritten Shelf Takedown shall have the right to select the investment
banker(s) and manager(s) to administer the offering (which shall consist of one or more reputable nationally recognized investment banks), subject to the Company’s prior approval which shall not be unreasonably withheld, conditioned or delayed.

 (g) Automatic Shelf Registration. Further, upon the Company becoming a Well-Known Seasoned Issuer, (i) the
Company shall give written notice to all of the Holders as promptly as practicable but in no event later than ten days thereafter, and such notice shall describe, in reasonable detail, the basis on which the Company has become a Well-Known Seasoned
Issuer, and (ii) the Company shall, as promptly as practicable, register, under an Automatic Shelf Registration Statement, the sale of all of the Registrable Securities in accordance with the terms of this Agreement. The Company shall use its
commercially 

  
 18 

 
reasonable efforts to file such Automatic Shelf Registration Statement as promptly as practicable, but in no event later than 30 days after it becomes a Well-Known Seasoned Issuer, and to cause
such Automatic Shelf Registration Statement to remain effective thereafter until there are no longer any Registrable Securities. The Company shall give written notice of filing such Registration Statement to all of the Holders as promptly as
practicable thereafter. At any time after the filing of an Automatic Shelf Registration Statement by the Company, if the Company is no longer a Well-Known Seasoned Issuer (the “Determination Date”), (A) within ten days
after such Determination Date, the Company shall give written notice thereof to all of the Holders and (B) within 30 days after such Determination Date, the Company shall file a Registration Statement on an appropriate form (or a post effective
amendment converting the Automatic Shelf Registration Statement to an appropriate form) covering all of the Registrable Securities, and use commercially reasonable efforts to have such Registration Statement declared effective as promptly as
practicable (but in no event more than 30 days) after the date the Automatic Shelf Registration Statement is no longer useable by the Holders to sell their Registrable Securities. 

(h) Additional Selling Stockholders and Additional Registrable Securities. 

(i) If the Company is not a Well-Known Seasoned Issuer, within 45 days after a written request by any Demand Holder or Second Demand
Holder to register for resale any additional Registrable Securities owned by such Demand Holders or Second Demand Holder, the Company shall file a Registration Statement substantially similar to the Shelf then effective, if any (each, a
“Follow-On Shelf”), to register for resale such Registrable Securities. The Company shall give written notice of the filing of the Follow-On Shelf at least 15 days prior to filing the Follow-On Shelf to all Holders of
Registrable Securities (the “Follow-On Registration Notice”) and shall include in such Follow-On Shelf all Registrable Securities with respect to which the Company has received written requests for inclusion therein within
ten days after sending the Follow-On Registration Notice. Notwithstanding the foregoing, the Company shall not be required to file a Follow-On Shelf (A) if the aggregate amount of Registrable Securities requested to be registered on such
Follow-On Shelf by all Holders that have not yet been registered represent less than 5% of the then outstanding Common Stock or (B) if the Company is not then eligible for use of Form S-3 for secondary offerings and the Company has filed a
Follow-On Shelf in the prior 180 days. The Company shall use commercially reasonable efforts to cause such Follow-On Shelf to be declared effective as promptly as practicable and in any event within 90 days of filing such Follow-On Shelf. Any
Registrable Securities requested to be registered pursuant to this Section 6(h)(i) that have not been registered on a Shelf or pursuant to Section 7 at the time the Follow-On Shelf is filed shall be registered pursuant to
such Follow-On Shelf. 
 (ii) If the Company is a Well-Known Seasoned Issuer, within ten Business Days after a written request
by one or more Holders of Registrable Securities to register for resale any additional Registrable Securities owned by such Holders, the Company shall make all necessary filings to include such Registrable Securities in the Automatic Shelf
Registration Statement filed pursuant to Section 6(g). 
 (iii) If a Form S-3 Shelf or Automatic Shelf Registration
Statement is effective, within five Business Days after written request therefor by a Holder of Registrable 

  
 19 

 
Securities, the Company shall file a prospectus supplement or current report on Form 8-K to add such Holder as a selling stockholder in such Form S-3 Shelf or Automatic Shelf Registration
Statement to the extent permitted under the rules and regulations promulgated by the Commission. 
 (i) Other Registration
Rights. Except as expressly contemplated by the Restructuring Documents, the Company represents and warrants that it is not a party to, or otherwise subject to, any other agreement granting registration rights to any other Person with respect to
any securities of the Company, including securities convertible, exercisable or exchangeable into or for shares of any equity securities of the Company. 
 7. Piggyback Takedowns. 
 (a) Right to Piggyback. Whenever the
Company proposes to register any of its securities (whether or not following a request by a holder of Common Stock) (a “Piggyback Registration”), or proposes to offer any Common Stock pursuant to a registration statement in
an Underwritten Offering of Common Stock under the Securities Act (whether or not following a request by a holder of Common Stock) (together with a Piggyback Registration, a “Piggyback Takedown”), the Company shall give
prompt written notice to all Holders of Registrable Securities of its intention to effect such Piggyback Takedown. In the case of a Piggyback Takedown that is an Underwritten Offering under a Shelf Registration, such notice shall be given not less
than ten Business Days prior to the expected date of commencement of marketing efforts for such Piggyback Takedown. In the case of a Piggyback Takedown that is an Underwritten Offering under a Registration Statement that is not a Shelf Registration,
such notice shall be given not less than ten Business Days prior to the expected date of filing of such Registration Statement. The Company shall, subject to the provisions of Section 7(b) and Section 7(c), include in such
Piggyback Takedown, as applicable, all Registrable Securities with respect to which the Company has received written requests for inclusion therein within five Business Days after sending the Company’s notice. Notwithstanding anything to the
contrary contained herein, (i) the Company may determine not to proceed with any Piggyback Takedown upon written notice to the Holders of Registrable Securities requesting to include their Registrable Securities in such Piggyback Takedown, and
(ii) any Holder of Registrable Securities may withdraw its request for inclusion in such Piggyback Takedown by giving written notice to the Company; provided, however, that the withdrawal shall be irrevocable and after making the
withdrawal, a Holder shall no longer have any right to include its Registrable Securities in that Piggyback Takedown. 
 (b)
Priority on Primary Piggyback Takedowns. If a Piggyback Takedown is an underwritten primary registration initiated by the Company, and the managing underwriters for a Piggyback Takedown advise the Company that the number of securities
requested to be included in such Piggyback Takedown exceeds the number which can be sold in an orderly manner in such offering within a price range acceptable to the Company, the Company shall include in such Piggyback Takedown the number which can
be so sold in the following order of priority: (i) first, the securities the Company proposes to sell; (ii) second, the Registrable Securities requested to be included in such Piggyback Takedown (pro rata among the
Holders of such Registrable Securities on the basis of the number of shares of Common Stock owned by each such Holder); and (iii) third, other securities requested to be included in such Piggyback Takedown. 

  
 20 

 (c) Priority on Piggyback Takedowns Initiated by Non-Holders. If a Piggyback Takedown
is an underwritten secondary registration requested by and filed on behalf of holders of the Company’s securities other than any Holder of Registrable Securities hereunder (“Other Holders”) and the managing underwriters
advise the Company that the number of securities requested to be included in such Piggyback Takedown exceeds the number which can be sold in an orderly manner in such offering within a price range acceptable to the Other Holders, the Company shall
include in such registration the number which can be so sold in the following order of priority: (i) first, the Registrable Securities requested to be included in such registration (pro rata among the holders of any such
securities and Registrable Securities on the basis of the number of securities and Registrable Securities owned by each such holder); (ii) second, the securities requested to be included therein by the Other Holders requesting such
registration (pro rata among the holders of any such securities on the basis of the number of securities owned by each such holder); and (iii) third, other securities requested to be included in such registration. 

(d) Selection of Underwriters. If any Piggyback Takedown is an underwritten offering, the Company will have the sole right to
select the investment banker(s) and manager(s) for the offering. 
 8. Suspension Period. 

(a) Suspension Period. Notwithstanding any provision of this Agreement to the contrary, if the Board determines in good faith that
the registration and distribution of Registrable Securities (i) would reasonably be expected to materially impede, delay or interfere with, or require premature disclosure of, any material financing, offering, acquisition, merger, corporate
reorganization, segment reclassification or discontinuance of operations that is required to be reflected in pro forma or restated financial statements that amends historical financial statement of the Company, or other significant transaction or
any negotiations, discussions or pending proposals with respect thereto, involving the Company or any of its subsidiaries, or (ii) would require disclosure of non-public material information, the disclosure of which would reasonably be expected
to materially and adversely affect the Company, the Company shall be entitled to suspend, for a reasonable period of time (each, a “Suspension Period”), the use of any Registration Statement or Prospectus and shall not be
required to amend or supplement the Registration Statement, any related Prospectus or any document incorporated therein by reference. The Company shall use its good faith efforts to amend the Registration Statement and/or Prospectus to correct such
untrue statement or omission as soon as reasonably practicable unless such amendment would reasonably be expected to have a material adverse effect on any proposal or plan of the Company to effect a merger, acquisition, disposition, financing,
reorganization, recapitalization or similar transaction, in each case that is material to the Company. The Company promptly will give written notice of any such Suspension Period to each
Person that has securities registered on a Registration Statement filed hereunder. 
 (b) Limitations on Suspension

 9. Holdback Agreements. 

(a) Holders of Registrable Securities. In connection with any Underwritten Offering or other underwritten public offering of
equity securities by the Company, no Holder of equity securities of the Company, or any securities convertible into or exchangeable or exercisable for such securities, shall effect any public sale or distribution (including sales pursuant to Rule
144) of equity securities of the Company, or any securities convertible into or exchangeable or exercisable for such securities, without prior written consent from the Company, (A) in the case of an Initial Public Offering, during the seven
days prior to and the 180-day period beginning on the date of the pricing of the Initial Public Offering or (B) solely with respect to any Holder participating in such Shelf Takedown or other underwritten public offering, during the seven days
prior to and the 90-day period beginning on the date of pricing of such Shelf Takedown or other underwritten public offering (the “Lock-Up Period”), except as part of the Underwritten Offering, and (i) unless the
underwriters managing the Underwritten Offering or other underwritten public equity offering by the Company otherwise agree by written consent and (ii) only if such Lock-Up Period (or a longer period) is applicable on substantially similar
terms to the Company and the executive officers and directors of the Company; provided that nothing herein will prevent any Holder that is a partnership, corporation, limited liability company or other entity from making a distribution of
Registrable Securities to the partners, stockholders, members or owners of interests thereof or a transfer to an Affiliate that is otherwise in compliance with the applicable securities laws, so long as such distributees or transferees agree to be
bound by the restrictions set forth in this Section 9(a). Each Holder agrees to execute a lock-up agreement in favor of the Company’s underwriters to such effect (in each case on substantially the same terms and conditions as all
Holders) and, in any event, that the Company’s underwriters in any relevant Underwritten Offering or other underwritten public offering shall be third party beneficiaries of this Section 9(a). 

(b) The Company. In connection with any Underwritten Offering, the Company shall not effect any public sale or distribution of its
equity securities, or any securities convertible into or exchangeable or exercisable for such securities (except pursuant to registrations on Form S-8 or Form S-4 under the Securities Act), during the seven days prior to and the 90-day period
beginning on the date of pricing of such Underwritten Offering. 
 10. Company Undertakings. 

Whenever Registrable Securities are registered pursuant to this Agreement, the Company shall use its commercially
reasonable efforts to effect the registration and the sale of such Registrable Securities as soon as reasonably practicable in accordance with the intended method of disposition thereof, and pursuant thereto the Company shall as expeditiously as
possible: 
 (a) before filing a Registration Statement or Prospectus or any amendments or supplements thereto, at the
Company’s expense, furnish to the Holders whose securities are covered by the Registration Statement copies of all such documents, other than documents that 

  
 22

such Holders; 
 (b) notify each Holder of Registrable Securities of the effectiveness of each Registration Statement and
prepare and file with the Commission such amendments and supplements to such Registration Statement and the Prospectus used in connection therewith as may be necessary to keep such Registration Statement effective for a period ending on the date on
which all Registrable Securities have been sold under such Registration Statement or have otherwise ceased to be Registrable Securities, and comply with the provisions of the Securities Act with respect to the disposition of all securities covered
by such Registration Statement during such period in accordance with the intended methods of disposition by the sellers thereof set forth in such Registration Statement;

any “issuer free writing prospectus” as such term is defined under Rule 433 promulgated under the Securities Act)), all exhibits and other documents filed therewith and such other documents as such seller or such managing

owned by such seller (provided that the Company shall not be required to (A) qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this subsection, (B) subject itself to
taxation in any such jurisdiction or (C) consent to general service of process in any such jurisdiction); 
 (e) notify
each seller of such Registrable Securities, Counsel to the Holders and the managing underwriters: (i) at any time when a Prospectus relating to the applicable Registration Statement is required to be delivered under the Securities Act,
(A) upon discovery that, or upon the happening of any event as a result of which, such Registration Statement, or the Prospectus or Free Writing Prospectus relating to such Registration Statement, or any document incorporated or deemed to be
incorporated therein by reference contains an untrue statement of a material fact or omits any fact necessary to make the statements in the Registration Statement or the Prospectus or Free Writing Prospectus relating thereto not misleading or
otherwise requires the making of any changes in such Registration Statement, Prospectus, Free Writing Prospectus or document, and, at the request of any such seller and subject to Section 8(a) hereof, the

Company shall promptly prepare a supplement or amendment to such Prospectus or Free Writing Prospectus, furnish a reasonable number of copies of such supplement or amendment to each seller of
such Registrable Securities, Counsel to the Holders and the managing underwriters and file such supplement or amendment with the Commission so that, as thereafter delivered to the purchasers of such Registrable Securities, such Prospectus or Free
Writing Prospectus as so amended or supplemented shall not contain an untrue statement of a material fact or omit to state any fact necessary to make the statements therein not misleading, (B) as soon as the Company becomes aware of any
comments or inquiries by the Commission or any requests by the Commission or any Federal or state governmental authority for amendments or supplements to a Registration Statement or related Prospectus or Free Writing Prospectus covering Registrable
Securities or for additional information relating thereto, (C) as soon as the Company becomes aware of the issuance or threatened issuance by the Commission of any stop order suspending or threatening to suspend the effectiveness of a
Registration Statement covering the Registrable Securities or (D) of the receipt by the Company of any notification with respect to the suspension of the qualification or exemption from qualification of any Registrable Security for sale in any
jurisdiction, or the initiation or threatening of any proceeding for such purpose; and (ii) when each Registration Statement or any amendment thereto has been filed with the Commission and when each Registration Statement or the related
Prospectus or Free Writing Prospectus or any Prospectus supplement or any post effective amendment thereto has become effective. 
 (f) use its commercially reasonable efforts to cause all such Registrable Securities (i) if the Common Stock is then listed on a securities exchange or included for quotation in a recognized trading
market, to continue to be so listed or included, (ii) if the Common Stock is not then listed on a national securities exchange or included for quotation in a recognized trading market, to, as promptly as practicable (subject to the limitations

included in such Underwritten Offering or the underwriters, if any, reasonably request in order to expedite or facilitate the disposition of such Registrable Securities (including effecting a stock split, a combination of shares, or other
recapitalization) and provide reasonable cooperation, including causing appropriate officers to attend and participate in “road shows” and analyst or investor presentations and such other selling or other informational meetings
organized by the underwriters, if any; provided, that the Company shall have no obligation to participate in “road shows” in connection with any Underwritten Offering in which the total offering price of the Registrable
Securities to be sold therein is less than $100 million;

documents of the Company, and cause the Company’s officers, directors, employees and independent accountants to supply all information and participate in any due diligence sessions reasonably requested by any such Holder, underwriter, attorney,

confidentiality thereof pursuant to a written agreement reasonably acceptable to the Company and the applicable underwriter (which shall contain customary exceptions thereto); 
 (j) permit any Holder of Registrable Securities, Counsel to the Holders, any underwriter participating in any disposition pursuant to a Registration Statement, and any other attorney, accountant or other
agent retained by such Holder of Registrable Securities or underwriter, to participate (including, but not limited to, reviewing, commenting on and attending all meetings) in the preparation of such Registration Statement and any Prospectus
supplements relating to a Underwritten Offering, if applicable; 
 (k) in the event of the issuance or threatened issuance of
any stop order suspending the effectiveness of a Registration Statement, or of any order suspending or preventing the use of any related Prospectus or suspending the qualification of any Common Stock included in such Registration Statement for sale

withdrawal of any order suspending or preventing the use of any related Prospectus or Free Writing Prospectus or suspending qualification of any Registrable Securities included in such Registration Statement for sale in any jurisdiction at the
earliest practicable date; 
 (l) in connection with any Underwritten Offering, obtain and furnish to each such Holder of
Registrable Securities including Registrable Securities in such Underwritten Offering a signed counterpart of (i) a cold comfort letter from the Company’s independent public accountants and (ii) a legal opinion of counsel to the
Company addressed to the relevant underwriters and/or such Holders of Registrable Securities, in each case in customary form and covering such matters of the type customarily covered by such letters as the managing underwriters and/or Holders of a
majority of the Registrable Securities included in such Underwritten Offering reasonably request; 
 (m) with respect to each
Free Writing Prospectus or other materials to be included in the Disclosure Package, ensure that no Registrable Securities be sold “by means of” (as defined in Rule 159A(b) promulgated under the Securities Act) such Free Writing
Prospectus or other materials without the prior written consent of a majority of the Holders of the Registrable Securities that are being sold pursuant to such Free Writing Prospectus, which Free Writing Prospectuses or other materials shall be
subject to the review of Counsel to the Holders; provided, however, the Company shall not be responsible or liable for any breach by a Holder that has not obtained the prior written consent of the Company pursuant to
Section 22(n); 

  
 25 

 (n) provide a CUSIP number for the Registrable Securities prior to the effective date of the

or regulator of any state with respect thereto; 
 (p) (i) prepare and file with the Commission such amendments and
supplements to each Registration Statement as may be necessary to comply with the provisions of the Securities Act, including post effective amendments to each Registration Statement as may be necessary to keep such Registration Statement
continuously effective for the applicable time period required hereunder, and if applicable, file any Registration Statements pursuant to Rule 462(b) promulgated under the Securities Act; (ii) cause the related Prospectus to be supplemented by
any required Prospectus supplement, and as so supplemented to be filed pursuant to Rule 424 (or any similar provisions then in force) promulgated under the Securities Act; (iii) comply with the provisions of the Securities Act and the Exchange
Act and any applicable securities exchange or other recognized trading market with respect to the disposition of all securities covered by such Registration Statement during such period in accordance with the intended methods of disposition by the
sellers thereof set forth in such Registration Statement as so amended or in such Prospectus as so supplemented; and (iv) provide additional information related to each Registration Statement as requested by, and obtain any required approval
necessary from, the Commission or any Federal or state governmental authority; 
 (q) cooperate with each Holder of Registrable
Securities and each underwriter participating in the disposition of such Registrable Securities and underwriters’ counsel in connection with any filings required to be made with FINRA;

(t) in the case of certificated Registrable Securities, cooperate with the participating Holders of Registrable Securities and the
managing underwriters to facilitate the 

  
 26 

 
timely preparation and delivery of certificates (not bearing any legends) representing Registrable Securities to be sold after receiving written representations from each participating Holder
that the Registrable Securities represented by the certificates so delivered by such Holder will be transferred in accordance with the Registration Statement, and enable such Registrable Securities to be in such denominations and registered in such
names as the Holders or managing underwriters may reasonably request at least two Business Days prior to any sale of Registrable Securities; and 
 (u) use its commercially reasonable efforts to take all other actions necessary to effect the registration and sale of the Registrable Securities contemplated hereby. 

11. Registration Expenses. 
 All Registration Expenses shall be borne by the Company. For the avoidance of doubt, subject to the proviso in Section 2(c) of this Agreement, all Registration Expenses in connection with any
registration initiated as a Demand Registration shall be borne by the Company regardless of whether or not such registration has become effective and whether or not such registration has counted as one of the permitted Long-Form Registrations
pursuant to Section 2(c) of this Agreement. All Selling Expenses relating to Registrable Securities registered shall be borne by the selling Holders of such Registrable Securities pro rata on the basis of the number of Registrable
Securities sold; provided, however, that the Company and each Holder agrees that if the Holder complies with the provisions of Section 3 such Holder shall not be required to pay any underwriting spread to any underwriter in the Initial
Public Offering implemented pursuant to the IPO Demand Registration or IPO Drag-Along Sale and that the Company will pay such underwriters a commission in lieu of such underwriting spread in connection with the Initial Public Offering implemented
pursuant to the IPO Demand Registration or IPO Drag-Along Sale; provided further, that the Company and each Holder agrees that if such Holder participates in the first underwritten Demand Registration or Underwritten Shelf Takedown after the
Initial Public Offering (or, in the event that the Initial Public Offering does not occur pursuant to an IPO Demand Registration or IPO Drag Along Sale, the first two underwritten Demand Registrations or Underwritten Shelf Takedowns), such Holder
shall not be required to pay any underwriting spread to any underwriter in such Demand Registration or Underwritten Shelf Takedown (or Demand Registrations or Underwritten Shelf Takedowns) and that the Company will pay such underwriters a commission
in lieu of such underwriting spread in connection with such Demand Registration or Underwritten Shelf Takedown (or Demand Registrations or Underwritten Shelf Takedowns).  

12. Hedging Transactions. 
 (a) The Company agrees that, in connection with any proposed Hedging Transaction, if, in the reasonable judgment of Counsel to the Holders, it is necessary or desirable to have a Registration Statement
under the Securities Act cover such Hedging Transaction or sales or transfers (whether short or long) of Registrable Securities in connection therewith, then 

  
 27 

 
the Company shall use its commercially reasonable efforts to take such actions (which may include the filing of a Prospectus supplement to include additional or changed information that is
material or is otherwise required to be disclosed, including a description of such Hedging Transaction, the name of the Hedging Counterparty, identification of the Hedging Counterparty or its Affiliates as underwriters or potential underwriters, if
applicable, or any change to the plan of distribution, but shall not include the filing of a post-effective amendment to a Registration Statement) as may reasonably be required to have such Hedging Transaction or sales or transfers of Registrable
Securities in connection therewith covered by a Registration Statement under the Securities Act in a manner consistent with the rights and obligations of the Company hereunder. 

(b) All Registration Statements in which Holders may include Registrable Securities under this Agreement shall be subject to the
provisions of this Section 12. The Hedging Counterparty shall be selected by the Holders of a majority of the Registrable Securities subject to the Hedging Transaction that is proposed to be effected. 

(c) If in connection with a Hedging Transaction, a Hedging Counterparty or any Affiliate thereof is (or may be considered) an underwriter
or selling stockholder, then it shall be required to provide customary indemnities to the Company regarding the plan of distribution and like matters. 
 (d) The Company further agrees to include, under the caption “Plan of Distribution” (or the equivalent caption), in each Registration Statement, and any related Prospectus (to the extent
such inclusion is permitted under applicable Commission regulations and is consistent with comments received from the Commission during any Commission review of the Registration Statement), language substantially in the form of Schedule I
hereto and to include in each Prospectus supplement filed in connection with any proposed Hedging Transaction language mutually agreed upon by the Company, the relevant Holders and the Hedging Counterparty describing such Hedging Transaction.

 (e) In connection with a Hedging Transaction, each Hedging Counterparty shall be treated in the same manner as a managing
underwriter for purposes of Section 10 of this Agreement. 
 13. Indemnification; Contribution. 

(a) Indemnification by the Company. The Company agrees to indemnify and hold harmless each Holder of Registrable Securities, the
Affiliates, directors, officers, employees, members, partners, managers and agents of each such Holder and each Person who controls any such Holder within the meaning of either the Securities Act or the Exchange Act, to the fullest extent permitted
by applicable law, from and against any and all losses, claims, damages, liabilities and expenses to which they or any of them may become subject insofar as such losses, claims, damages, liabilities and expenses (or actions in respect thereof) arise
out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact contained in a Registration Statement as originally filed or in any amendment thereof, or the Disclosure Package, or any preliminary, final or
summary Prospectus or Free Writing Prospectus included in any such Registration Statement, or in any amendment thereof or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact

  
 28 

 
required to be stated therein or necessary to make the statements therein not misleading or (ii) any violation or alleged violation by the Company of the Securities Act, the Exchange Act,
any other federal law, any state or foreign securities law, or any rule or regulation promulgated under of the foregoing laws, relating to the offer or sale of the Registrable Securities, and in any such case, the Company agrees to reimburse each
such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating, preparing or defending any such loss, claim, damage, liability, action or investigation (whether or not the
indemnified party is a party to any proceeding); provided, however, that the Company will not be liable in any case to the extent that any such loss, claim, damage, liability or expense arises out of or is based upon any such untrue
statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information relating to such Holder furnished to the Company by or on behalf of any such Holder specifically for
inclusion therein, including any notice and questionnaire. This indemnity agreement will be in addition to any liability which the Company may otherwise have. 
 (b) Indemnification by the Holders. Each Holder severally (and not jointly) agrees to indemnify and hold harmless the Company and each of its Affiliates, directors, employees, members, managers and
agents and each Person who controls the Company within the meaning of either the Securities Act or the Exchange Act, to the fullest extent permitted by applicable law, from and against any and all losses, claims, damages or liabilities to which they
or any of them may become subject insofar as such losses, claims, damages or liabilities arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in a Registration Statement as originally filed or
in any amendment thereof, or in the Disclosure Package or any Holder Free Writing Prospectus, preliminary, final or summary Prospectus included in any such Registration Statement, or in any amendment thereof 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, to the extent, but only to the extent, that any such untrue statement or
alleged untrue statement or omission or alleged omission is contained in any written information relating to such Holder furnished to the Company by or on behalf of such Holder specifically for inclusion therein; provided, however,
that the total amount to be indemnified by such Holder pursuant to this Section 13(b) shall be limited to the net proceeds (after deducting underwriters’ discounts and commissions) received by such Holder in the offering to which
such Registration Statement or Prospectus relates; provided, further, that a Holder shall not be liable in any case to the extent that prior to the filing of any such Registration Statement or Disclosure Package, or any amendment
thereof or supplement thereto, each Holder has furnished in writing to the Company, information expressly for use in, and within a reasonable period of time prior to the effectiveness, filing or use of such Registration Statement or Disclosure
Package, or any amendment thereof or supplement thereto which corrected or made not misleading information previously provided to the Company. This indemnity agreement will be in addition to any liability which any such Holder may otherwise have.

 (c) Conduct of Indemnification Proceedings. Promptly after receipt by an indemnified party under this
Section 13 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 13, notify the indemnifying party in writing
of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under 

  
 29 

 
Section 13(a) or Section 13(b) above unless and to the extent such action and such failure results in material prejudice to the indemnifying party and forfeiture by the
indemnifying party of substantial rights and defenses; and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in Section 13(a)
or Section 13(b) above. The 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
satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, except as provided in the next sentence, after notice from the indemnifying party to such
indemnified party of its election to so assume the defense thereof, the indemnifying party shall not be liable to such indemnified party for any legal expenses of other counsel or any other expenses subsequently incurred by such indemnified party in
connection with the defense thereof other than reasonable costs of investigation. Notwithstanding the indemnifying party’s rights in the prior sentence, the indemnified party shall have the right to employ one firm of separate counsel (and one
local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if: 

(i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with an actual or
potential conflict of interest; 
 (ii) the actual or potential defendants in, or targets of, any such action include both the
indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the
indemnifying party; 
 (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to
represent the indemnified party within 10 days after notice of the institution of such action or such earlier time as may be necessary to pursue appropriate defenses, rights, and remedies; or 

(iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party.

 No indemnifying party shall, in connection with any one action or separate but substantially similar or related actions in the same
jurisdiction arising out of the same general circumstances or allegations, be liable for the fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) for all indemnified parties. An indemnifying party shall
not be liable under this Section 13 to any indemnified party regarding any settlement or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which
indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent is consented to by such indemnifying party, which
consent shall not be unreasonably withheld. No indemnifying party, in the defense of any such claim or litigation, shall, except with the consent of each indemnified party, consent to entry of any judgment or enter into any settlement or compromise
that (x) does not include as an unconditional term thereof the giving by the claimant or plaintiff therein, to such indemnified 

  
 30 

 
party, of a full and final release from all liability in respect to such claim or litigation or (y) includes a statement as to, or an admission of, fault, culpability or a failure to act by
or on behalf of such indemnified party. 
 (d) Contribution. 

(i) In the event that the indemnity provided in Section 13(a) or Section 13(b) above is unavailable to or
insufficient to hold harmless an indemnified party for any reason, then each applicable indemnifying party agrees to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in
connection with investigating, preparing or defending same) (collectively, “Losses”) to which such indemnifying party may be subject in such proportion as is appropriate to reflect the relative fault of the indemnifying party
on the one hand and the indemnified party on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof) from the offering of the Common Stock. If, however,
the allocation provided by the immediately preceding sentence is not permitted by applicable law, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect
not only such relative fault but also the relative benefits received by the indemnifying party on the one hand and the indemnified party on the other, as well as any other relevant equitable considerations. The relative fault 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 indemnifying party on the one hand or the
indemnified party on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. 
 (ii) The parties agree that it would not be just and equitable if contribution pursuant to this Section 13(d) were determined by pro rata allocation (even if the Holders of Registrable
Securities 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 above in this
Section 13(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 in this Section 13(d) shall be deemed to include
any legal or other expenses reasonably incurred by such indemnified party in connection with investigating, preparing or defending any such action or claim. 
 (iii) Notwithstanding the provisions of this Section 13(d), 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. 
 (iv) For purposes of this
Section 13, each Person who controls any Holder of Registrable Securities, agent or underwriter within the meaning of either the Securities Act or the Exchange Act and each Affiliate, director, officer, employee, member, partner, manager
and agent of any such Holder, agent or underwriter shall have the same rights to contribution as such Holder, agent or underwriter, and each Person who controls the Company within the meaning of either the Securities Act or the Exchange Act and each
officer and director of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this Section 13(d). 

  
 31 

 (e) The provisions of this Section 13 will remain in full force and effect,
regardless of any investigation made by or on behalf of any Holder of Registrable Securities or the Company or any of the Affiliates, directors, officers, employees, members, partners, managers, agents or controlling Persons referred to in this
Section 13 hereof, and will survive the transfer of Registrable Securities. 
 (f) To the extent any indemnification
by an indemnifying party is prohibited or limited by law, the indemnifying party agrees to make the maximum contribution with respect to any amounts for which it would otherwise be liable under Section 13 to the fullest extent permitted
by law; provided, however, that: (i) no Person involved in the sale of Registrable Securities which Person is guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) in connection
with such sale shall be entitled to contribution from any Person involved in such sale of Registrable Securities who was not guilty of fraudulent misrepresentation; and (ii) contribution by any seller of Registrable Securities shall be limited
in amount to the net amount of proceeds received by such seller from the sale of such Registrable Securities. 
 14.
Participation in Underwritten Offering/Sale of Registrable Securities. 
 (a) No Person may participate in any Underwritten
Offering hereunder unless such Person (i) agrees to enter into an underwriting agreement in customary form and provide the representations and warranties, and indemnities to the underwriters and the Company and to sell such Person’s
securities on the basis provided in any such underwriting agreement and (ii) completes and executes all questionnaires, powers of attorney, custody agreements, indemnities, underwriting agreements and other documents reasonably required under
the terms of such underwriting arrangements; provided that no Holder of Registrable Securities included in any Underwritten Offering shall be required to make any representations or warranties to the Company or the underwriters (other than
representations and warranties regarding (A) such Holder’s ownership of its Registrable Securities to be sold or transferred free and clear of liens, (B) such Holder’s power and authority to effect, and lack of conflicts in
effecting, such transfer and (C) such matters pertaining to compliance with securities laws as may be reasonably requested) or to undertake any indemnification obligations to the Company, except as otherwise provided in
Section 13(b) hereof, or to the underwriters, except to the extent of the indemnification being given to the Company and its controlling persons in Section 13(b) hereof. 

(b) Each Person that has securities registered on a Registration Statement filed hereunder agrees that, upon receipt of any notice
contemplated in Section 8(a), such Person will forthwith discontinue the disposition of its Registrable Securities pursuant to the applicable Registration Statement. 

15. Rule 144. 
 With a view to making available to the Holders of Registrable Securities the benefits of Rule 144 promulgated under the Securities Act, the 

  
 32 

 
Company covenants that it will (a) make available information necessary to comply with Rule 144, if available with respect to resales of the Registrable Securities under the Securities Act,
at all times, and (b) take such further action as such Holder 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
limitation of the exemptions provided by Rule 144 promulgated under the Securities Act (if available with respect to resales of the Registrable Securities), as such rule may be amended from time to time. Upon the reasonable request of any Holder of
Registrable Securities, the Company will deliver to such Holder a written statement as to whether it has complied with such information requirements, and, if not, the specific reasons for non-compliance. 

16. Private Placement. 
 Except for Section 9(a), 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

facilitate such sale or transfer, including providing reasonable due diligence access to potential purchasers. 
 17.
Reporting. 
 (a) The Company will use its commercially reasonable efforts to become a “voluntary filer” of periodic
reports under the Exchange Act by March 31, 2013 without registering the Common Stock on a Form 10 registration statement; provided, that if the Company has a registration statement on file with the Commission and it is diligently
pursuing the effectiveness of such registration statement, then the obligation set forth in the first sentence of this Section 17(a) shall be suspended for 90 days. If the Company does not become a “voluntary filer” by March 31,
2013, the Company will post on its website, beginning April 1, 2013 (and including an Annual Report on Form 10-K for the year ended December 31, 2012), the same information (including all periodic reports) and at such times, that it would
be required to file if it was subject to Section 15(d) of the Exchange Act. 
 (b) Notwithstanding the foregoing, as of the
Effective Date, the Company shall make publicly available on a website such information, and at such times, as the Company would be required to file pursuant to the reporting requirements of the Exchange Act, including: 

(i) Within 45 days after the end of each of the first three fiscal quarters of each fiscal year, quarterly management reports and
unaudited financial statements, all in reasonable detail, together with a “Management’s Discussion and Analysis of Financial Condition and Results of Operations” that describes the financial condition and results of operations of
Holdings and its consolidated subsidiaries similar to Form 10-Q information; 
 (ii) Within 90 days after the end of each
fiscal year, audited GAAP financial statements all in reasonable detail, together with a “Management’s Discussion and 

  
 33 

 
Analysis of Financial Condition and Results of Operations” that describes the financial condition and results of operations of Holdings and its consolidated subsidiaries similar to Form 10-K
information; 
 (iii) within five Business Days after the occurrence of an event that would require information about such
event to be provided to the Commission on Form 8-K , a current report with such information required to be contained in such a filing with the Commission on Form 8-K; and 
 (iv) unless otherwise required to be provided to Holders, such reports (i) shall not be required to comply with Section 302 or Section 404 of the Sarbanes-Oxley Act of 2002, or related
Items 307 and 308 of Regulation S-K promulgated by the SEC, or Item 10(e) of Regulation S-K (with respect to any non-GAAP financial measures contained therein), in each case, and (ii) will not be required to comply with Item 405 of
Regulation S-K promulgated by the SEC. 
 (c) To the extent not satisfied by the foregoing, the Company agrees that it will
furnish to Holders and to securities analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act. 

18. Street Name Trading. Unless an Initial Public Offering has been consummated, on October 1, 2013, the Company will
(i) file a Form 10 registration statement to register the Common Stock under the Exchange Act, (ii) timely apply to list the Common Stock on the New York Stock Exchange or Nasdaq Market and (iii) timely apply for the Common Stock to
be made DTC eligible (collectively, the “34 Act Registration Filings”), such ‘34 Act Registration Filings to be effective in each instance, on but not before December 2, 2013; it being understood that at any time
prior to such December 2, 2013 date (unless the Company has consummated an Initial Public Offering prior to such date), holders of a majority of the outstanding shares of Common Stock (the “Majority Holders”) may direct
the Company to withdraw or delay the effectiveness of all such filings and applications relating to the ‘34 Act Registration Filings and have the Common Stock remain book-entry only. If the Majority Holders direct the Company to withdraw or
delay the ‘34 Act Registration Filings, then such Majority Holders shall also determine in such direction a new date for proceeding with the ‘34 Act Registration Filings, at which time the Company will proceed with and diligently pursue
the effectiveness of the ‘34 Act Registration Filings unless prior to such new date the Majority Holders determine to further extend the date of filing the ‘34 Act Registration Filings. 

19. Confidentiality. 
 (a) At any time prior to the earlier of: (i) the effectiveness of the ’34 Act Registration Filings or (ii) an Initial Public Offering, at the request of a Holder, the Company will provide
Confidential Information to any Holder who has entered into a confidentiality agreement with the Company (a “Transfer Confidentiality Agreement”) substantially in the form attached as Exhibit A and each such
Holder shall be permitted to disclose and discuss any Confidential Information with any prospective transferee of Common Stock, other securities of the Company, and loans or debt obligations of the Company or any of its direct or indirect
subsidiaries (“Prospective Transferee”), the professional advisors (including, but not limited to, 

  
 34

Representatives”) provided that (i) neither such Prospective Transferee nor any Prospective Transferee Representative is a competitor of the Company or any of its subsidiaries, as determined in good faith by the Company, and
(ii) such Prospective Transferee and each Prospective Transferee Representative has entered into a Transfer Confidentiality Agreement. 
 (b) The term “Confidential Information” includes (i) all confidential or proprietary information furnished by the Company or any of its representatives after the date hereof,
whether oral or written or by visual inspection, and regardless of the manner in which it is furnished and (ii) those portions of analyses, compilations, forecasts, studies, interpretations or other documents prepared by such Holder and its
Affiliates and its and their directors, officers, employees, agents, professional advisors (including, but not limited to, attorneys, accountants, consultants and financial advisors), investors, prospective investors and financing sources who
(A) need to know the Confidential Information, (B) have been informed of the confidential nature of the Confidential Information and (C) are bound by an obligation of confidentiality to such Holder sufficient to ensure compliance with
the terms of this Agreement (such Persons are referred to as the Holder’s “Representatives”), that reflect or are based upon, in whole or part, the information furnished to such Holder or its Representatives. The term
“Confidential Information” does not include any information that (A) at the time of disclosure or thereafter is available to or known by the public (other than as a result of its disclosure by such Holder or its
Representatives in breach of this Agreement), (B) was available to such Holder or any of its Representatives on a non-confidential basis before disclosure by the Company, (C) becomes available to such Holder or any of its actual
Representatives on a non-confidential basis from a Person who, to such Holder’s or its Representatives’ knowledge, is not known by such Holder or its Representatives to be bound by a confidentiality agreement with the Company and is not
otherwise prohibited from transmitting the information to any Holder or such Holder’s Representatives or (iv) was independently developed by such Holder or its Representatives without use of the Confidential Information. The Confidential
Information shall remain the property of the Company. Except as expressly set forth in this Section 19, no rights to use, license or otherwise exploit the Confidential Information are granted to any Holder or its Representatives, by
implication or otherwise, and no Holder shall replicate, decompile or reverse engineer any Confidential Information (except as set forth herein) or make any attempts to do so. No Holder or its Representatives will acquire any rights with respect to
the Confidential Information, all of which rights shall remain exclusively with the Company. 
 20. Transfer of
Registration Rights; Registrable Securities. 
 The rights of a Holder hereunder shall be transferred, assigned,
or otherwise conveyed on a pro rata basis in connection with any transfer, assignment, or other conveyance of Registrable Securities, and a holder may transfer, assign or convey Registrable Securities to any transferee or assignee, only if
all of the following conditions are satisfied with respect to any such transfer, assignment or conveyance: (a) such transfer or assignment is effected in accordance with applicable securities laws; (b) prior to the Registrable Securities
becoming DTC eligible, such transferee or assignee agrees in writing to become subject to the terms of this Agreement by executing a joinder agreement; and (c)

  
 35 

 
the Company is given written notice by such Holder of such transfer or assignment, stating the name and address of the transferee or assignee, identifying the Registrable Securities with respect
to which such rights are being transferred or assigned. Upon the transfer of rights and Registrable Securities in accordance with this Section 20, the transferee shall be a Holder for all purposes of this Agreement. Any transfer,
assignment or other conveyance of the rights or Registrable Securities of a Holder in breach of this Agreement shall be void and of no effect. 
 21. Amendment, Modification and Waivers; Further Assurances. 
 (a)
Amendment. This Agreement may be not amended without the consent of the Company and the written consent of holders of at least 66 2/3% of the issued and outstanding Common Stock; provided that no such amendment, action or omission that
adversely affects, alters or changes the interests of any Holder shall be effective against such Holder without the prior written consent of such Holder. 
 (b) Effect of Waiver. No waiver of any terms or conditions of this Agreement shall operate as a waiver of any other breach of such terms and conditions or any other term or condition, nor shall any
failure to enforce any provision hereof operate as a waiver of such provision or of any other provision hereof. No written waiver hereunder, unless it by its own terms explicitly provides to the contrary, shall be construed to effect a continuing
waiver of the provisions being waived and no such waiver in any instance shall constitute a waiver in any other instance or for any other purpose or impair the right of the party against whom such waiver is claimed in all other instances or for all
other purposes to require full compliance with such provision. The failure of any party to enforce any provision of this Agreement shall not be construed as a waiver of such provision and shall not affect the right of such party thereafter to
enforce each provision of this Agreement in accordance with its terms. 
 (c) Further Assurances. Each of the parties
hereto shall execute all such further instruments and documents and take all such further action as any other party hereto may reasonably require in order to effectuate the terms and purposes of this Agreement. 

22. Miscellaneous. 
 (a) Adjustments. If, and as often as, there are any changes in the Common Stock by way of stock split, stock dividend, combination or reclassification, or through merger, consolidation,
reorganization, recapitalization, conversion or sale, or by any other means, appropriate adjustment shall be made in the provisions of this Agreement, as may be required, so that the rights, privileges, duties and obligations hereunder shall
continue with respect to the Common Stock as so changed. 
 (b) Successors and Assigns. All covenants and agreements in
this Agreement by or on behalf of any of the parties hereto shall bind and inure to the benefit of the respective successors and assigns of the parties hereto (including any trustee in bankruptcy) whether so expressed or not. In addition, whether or
not any express assignment has been made, the provisions of this Agreement which are for the benefit of purchasers or Holders of Registrable 

  
 36 

 
Securities are also for the benefit of, and enforceable by, any subsequent Holder of Registrable Securities. No assignment or delegation of this Agreement by the Company, or any of the
Company’s rights, interests or obligations hereunder, shall be effective against any Holder without the prior written consent of such Holder. 
 (c) Remedies; Specific Performance. Any Person having rights under any provision of this Agreement shall be entitled to enforce such rights specifically, to recover damages caused by reason of any
breach of any provision of this Agreement and to exercise all other rights existing in their favor. The parties hereto agree and acknowledge that money damages would not be an adequate remedy for any breach of the provisions of this Agreement and
that any party may in its sole discretion apply to any court of law or equity of competent jurisdiction for specific performance and/or injunctive relief (without posting any bond or other security) in order to enforce or prevent violation of the
provisions of this Agreement and shall not be required to prove irreparable injury to such party or that such party does not have an adequate remedy at law with respect to any breach of this Agreement (each of which elements the parties admit). The
parties hereto further agree and acknowledge that each and every obligation applicable to it contained in this Agreement shall be specifically enforceable against it and hereby waives and agrees not to assert any defenses against an action for
specific performance of their respective obligations hereunder. All rights and remedies existing under this Agreement are cumulative to, and not exclusive of, any rights or remedies available under this Agreement or otherwise.

 Schedule I 
 Hedging Transaction Language 
 A selling stockholder may also enter into hedging
and/or monetization transactions. For example, a selling stockholder may: 
 (a) enter into transactions with a broker-dealer or
affiliate of a broker-dealer or other third party in connection with which that other party will become a selling stockholder and engage in short sales of the common stock under this prospectus, in which case the other party may use shares of common
stock received from the selling stockholder to close out any short positions; 
 (b) itself sell short common stock under this
prospectus and use shares of common stock held by it to close out any short position; 
 (c) enter into options, forwards or
other transactions that require the selling stockholder to deliver, in a transaction exempt from registration under the Securities Act, common stock to a broker-dealer or an affiliate of a broker-dealer or other third party who may then become a
selling stockholder and publicly resell or otherwise transfer that common stock under this prospectus; or 
 (d) loan or pledge
common stock to a broker-dealer or affiliate of a broker-dealer or other third party who may then become a selling stockholder and sell the loaned shares or, in an event of default in the case of a pledge, become a selling stockholder and sell the
pledged shares, under this prospectus.
