 SECTION 2. Securities Subject to
this Agreement. 
 (a) Transfer Restricted Securities. The securities entitled to the benefits of this Agreement are
the Transfer Restricted Securities. 
 (b) Holders of Transfer Restricted Securities. A Person is deemed to be a holder
of Transfer Restricted Securities (each, a “Holder”) whenever such Person owns Transfer Restricted Securities. 

SECTION 3. Registered Exchange Offer. 
 (a) Unless the Exchange Offer shall not be permissible under applicable law or Commission policy (after the procedures set forth in Section 6(a) hereof have been complied with), each of the Company
and the Guarantors shall use commercially reasonable efforts to (i) cause to be filed with the Commission a Registration Statement under the Securities Act relating to the Exchange Securities and the Exchange Offer, (ii) cause such
Registration Statement to become effective and (iii) Consummate the Exchange Offer no later than the Exchange Date. In connection with the foregoing, the Company and the Guarantors shall (A) file all pre-effective amendments to such
Registration Statement as may be necessary in order to cause such Registration Statement to become effective, (B) if applicable, file a post-effective amendment to such Registration Statement pursuant to Rule 430A under the Securities Act and
(C) cause all necessary filings in connection with the registration and qualification of the Exchange Securities to be made under the state securities or blue sky laws of such jurisdictions as are necessary to permit Consummation of the
Exchange Offer. The Exchange Offer shall be on the appropriate form permitting registration of the Exchange Securities to be offered in exchange for the Transfer Restricted Securities and to permit resales of Initial Securities held by
Broker-Dealers as contemplated by Section 3(c) hereof. 
 (b) The Company and the Guarantors shall cause the Exchange Offer
Registration Statement to be effective continuously and shall keep the Exchange Offer open for a period of not less than the minimum period required under applicable federal and state securities laws to Consummate the Exchange Offer; provided,
however, that in no event shall such period be less than 20 Business Days after the date notice of the Exchange Offer is mailed to the Holders. The Company shall cause the Exchange Offer to comply with all applicable federal and state securities
laws. No securities other than the Exchange Securities shall be included in the Exchange Offer Registration Statement. 
 (c)
The Company shall indicate in a “Plan of Distribution” section contained in the Prospectus forming a part of the Exchange Offer Registration Statement that any Broker-Dealer who holds Initial Securities that are Transfer Restricted
Securities and that were acquired for its own account as a result of market-making activities or other trading activities (other than Transfer Restricted Securities acquired directly from the Company), may exchange such Initial Securities pursuant
to the Exchange Offer; however, such Broker-Dealer may be deemed to be an “underwriter” within the meaning of the Securities Act and must, therefore, deliver a prospectus 

  
 -4-

 
meeting the requirements of the Securities Act in connection with any resales of the Exchange Securities received by such Broker-Dealer in the Exchange Offer, which prospectus delivery
requirement may be satisfied by the delivery by such Broker-Dealer of the Prospectus contained in the Exchange Offer Registration Statement. Such “Plan of Distribution” section shall also contain all other information with respect to such
resales by Broker-Dealers that the Commission may require in order to permit such resales pursuant thereto, but such “Plan of Distribution” shall not name any such Broker-Dealer or disclose the amount of Initial Securities held by any such
Broker-Dealer except to the extent required by the Commission as a result of a change in policy after the date of this Agreement. 
 Each of the Company and the Guarantors shall use commercially reasonable efforts to cause the Exchange Offer Registration Statement to be continuously effective, supplemented and amended as required by
the provisions of Section 6(c) hereof to the extent necessary to ensure that it is available for resales of Initial Securities acquired by Broker-Dealers for their own accounts as a result of market-making activities or other trading
activities, and to ensure that it conforms with the requirements of this Agreement, the Securities Act and the policies, rules and regulations of the Commission as announced from time to time, for a period ending on the earlier of (i) 90 days
from the date on which the Exchange Offer Registration Statement is declared effective and (ii) the date on which a Broker-Dealer is no longer required to deliver a prospectus in connection with market-making or other trading activities.

 The Company shall provide sufficient copies of the latest version of such Prospectus to Broker-Dealers promptly upon request
at any time during such 90-day (or shorter as provided in the foregoing sentence) period in order to facilitate such resales. 

SECTION 4. Shelf Registration. 
 (a) Shelf Registration. If (i) the Company is not required to file an Exchange Offer Registration Statement or to Consummate the Exchange Offer because the Exchange Offer is not permitted by
applicable law or Commission policy (after the procedures set forth in Section 6(a) hereof have been complied with), (ii) for any reason the Exchange Offer is not Consummated by the Exchange Date, or (iii) with respect to any Holder
of Transfer Restricted Securities (A) such Holder is prohibited by applicable law or Commission policy from participating in the Exchange Offer, (B) such Holder may not resell the Exchange Securities acquired by it in the Exchange Offer to
the public without delivering a prospectus and that the Prospectus contained in the Exchange Offer Registration Statement is not appropriate or available for such resales by such Holder, or (C) such Holder is a Broker-Dealer and holds Initial
Securities acquired directly from the Company or one of its affiliates, then, upon such Holder’s request, the Company and the Guarantors shall: 
 (x) as promptly as practicable, cause to be filed a shelf registration statement pursuant to Rule 415 under the Securities Act, which may be an amendment to the Exchange Offer Registration Statement (in
either event, the “Shelf Registration Statement”), on or prior to the earlier to occur of (1) the 60th day after the date on which the Company determines that it is not required to file the Exchange Offer Registration Statement and
(2) the 60th day after the date on which the Company receives notice from a Holder of Transfer Restricted Securities as contemplated by clause (iii) above (or if such 60th day is 

  
 -5-

 
not a Business Day, the next succeeding Business Day) (such date being the “Shelf Filing Deadline”), which Shelf Registration Statement shall provide for resales of all Transfer
Restricted Securities the Holders of which shall have provided the information required pursuant to Section 4(b) hereof; and 
 (y) use commercially reasonable efforts to cause such Shelf Registration Statement to be declared effective by the Commission on or before the 60th day after the Shelf Filing Deadline (or if such 60th day
is not a Business Day, the next succeeding Business Day). 
 Each of the Company and the Guarantors shall use commercially
reasonable efforts to keep such Shelf Registration Statement continuously effective, supplemented and amended as required by the provisions of Sections 6(b) and (c) hereof to the extent necessary to ensure that it is available for resales of
Initial Securities by the Holders of Transfer Restricted Securities entitled to the benefit of this Section 4(a), and to ensure that it conforms with the requirements of this Agreement, the Securities Act and the policies, rules and regulations
of the Commission as announced from time to time, for a period of at least two years following the Closing Date (or shorter period that will terminate when all Initial Securities covered by the Shelf Registration Statement have been sold pursuant to
such Shelf Registration Statement). 
 (b) Provision by Holders of Certain Information in Connection with the Shelf
Registration Statement. No Holder of Transfer Restricted Securities may include any of its Transfer Restricted Securities in any Shelf Registration Statement pursuant to this Agreement unless and until such Holder furnishes to the Company in
writing, within 20 Business Days after receipt of a request therefor, such information as the Company may reasonably request for use in connection with any Shelf Registration Statement or Prospectus or preliminary Prospectus included therein. Each
Holder as to which any Shelf Registration Statement is being effected agrees to furnish promptly to the Company all information required to be disclosed in order to make the information previously furnished to the Company by such Holder not
materially misleading. 
 SECTION 5. Additional Interest. If (i) the Exchange Offer has not been Consummated by
the Exchange Date, (ii) the Shelf Registration Statement, if required, has not been declared effective by the Commission within 60 days of the Shelf Filing Deadline (or if such 60th day is not a Business Day, the next succeeding Business Day)
or (iii) any Shelf Registration Statement required by this Agreement is filed and has been declared effective but shall thereafter cease to be effective or fail to be usable for its intended purpose for more than 90 days in any 12-month period
(each such event referred to in clauses (i) through (iii), a “Registration Default”), the Company hereby agrees that the interest rate borne by the Transfer Restricted Securities shall be increased by 0.25% per annum during the
90-day period immediately following the occurrence of any Registration Default and shall increase by 0.25% per annum at the end of each subsequent 90-day period, but in no event shall such increase exceed 1.00% per annum (“Additional
Interest”). Following the cure of all Registration Defaults relating to any particular Transfer Restricted Securities, the interest rate borne by the relevant Transfer Restricted Securities will be reduced to the original interest rate borne by
such Transfer Restricted Securities; provided, however, that, if after any such reduction in interest rate, a different Registration Default occurs, the interest rate borne by the relevant Transfer Restricted Securities shall again be
increased pursuant to the foregoing provisions. 

  
 -6-

 All obligations of the Company and the Guarantors set forth in the preceding paragraph that
are outstanding with respect to any Transfer Restricted Security at the time such security ceases to be a Transfer Restricted Security shall survive until such time as all such obligations with respect to such security shall have been satisfied in
full. 
 SECTION 6. Registration Procedures. 

(a) Exchange Offer Registration Statement. In connection with the Exchange Offer, the Company and the Guarantors shall comply with
all of the applicable provisions of Section 6 hereof, shall use commercially reasonable efforts to effect such exchange to permit the sale of Transfer Restricted Securities being sold in accordance with the intended method or methods of
distribution thereof, and shall comply with all of the following provisions: 
 (i) If in the reasonable opinion
of counsel to the Company there is a question as to whether the Exchange Offer is permitted by applicable law, each of the Company and the Guarantors hereby agrees to seek a no-action letter or other favorable decision from the Commission allowing
the Company and the Guarantors to Consummate an Exchange Offer for such Initial Securities. Each of the Company and the Guarantors hereby agrees to pursue the issuance of such a decision to the Commission staff level but shall not be required to
take commercially unreasonable action to effect a change of Commission policy. Each of the Company and the Guarantors hereby agrees, however, to (A) participate in telephonic conferences with the Commission, (B) deliver to the Commission
staff an analysis prepared by counsel to the Company setting forth the legal bases, if any, upon which such counsel has concluded that such an Exchange Offer should be permitted and (C) diligently pursue a favorable resolution by the Commission
staff of such submission. 
 (ii) As a condition to its participation in the Exchange Offer pursuant to the terms
of this Agreement, each Holder of Transfer Restricted Securities shall furnish, upon the request of the Company, prior to the Consummation thereof, a written representation to the Company (which may be contained in the letter of transmittal
contemplated by the Exchange Offer Registration Statement) to the effect that (A) it is not an affiliate of the Company, (B) it is not engaged in, and does not intend to engage in, and has no arrangement or understanding with any Person to
participate in, a distribution of the Exchange Securities to be issued in the Exchange Offer and (C) it is acquiring the Exchange Securities in its ordinary course of business. In addition, all such Holders of Transfer Restricted Securities
shall otherwise cooperate in the Company’s preparations for the Exchange Offer. Each Holder hereby acknowledges and agrees that any Broker-Dealer and any such Holder using the Exchange Offer to participate in a distribution of the securities to
be acquired in the Exchange Offer (1) could not under Commission policy as in effect on the date of this Agreement rely on the position of the Commission enunciated in Morgan Stanley and Co., Inc. (available June 5, 1991) and
Exxon Capital Holdings Corporation (available May 13, 1988), as interpreted in the Commission’s letter to Shearman & Sterling dated July 2, 1993, and similar no-action letters (which may include any no-action letter
obtained pursuant to clause (i) above), and (2) must comply with the registration and prospectus delivery requirements of the Securities Act in connection with a secondary resale transaction and that such a secondary resale transaction
should be covered by 

  
 -7-

 
an effective registration statement containing the selling security holder information required by Item 507 or 508, as applicable, of Regulation S-K if the resales are of Exchange Securities
obtained by such Holder in exchange for Initial Securities acquired by such Holder directly from the Company. 
 (b) Shelf
Registration Statement. In connection with the Shelf Registration Statement, each of the Company and the Guarantors shall comply with all the provisions of Section 6(c) hereof and shall use commercially reasonable efforts to effect such
registration to permit the sale of the Transfer Restricted Securities being sold in accordance with the intended method or methods of distribution thereof, and pursuant thereto each of the Company and the Guarantors will as expeditiously as possible
prepare and file with the Commission a Registration Statement relating to the registration on any appropriate form under the Securities Act, which form shall be available for the sale of the Transfer Restricted Securities in accordance with the
intended method or methods of distribution thereof. 
 (c) General Provisions. In connection with any Registration
Statement and any related Prospectus required by this Agreement to permit the sale or resale of Transfer Restricted Securities (including, without limitation, any Registration Statement and the related Prospectus required to permit resales of
Initial Securities by Broker-Dealers), each of the Company and the Guarantors shall, as applicable: 
 (i) use
commercially reasonable efforts to keep such Registration Statement continuously effective and provide all requisite financial statements (including, if required by the Securities Act or any regulation thereunder, financial statements of the
Guarantors for the period specified in Section 3 or 4 hereof, as applicable; upon the occurrence of any event that would cause any such Registration Statement or the Prospectus contained therein (A) to contain a material misstatement or
omission or (B) not to be effective and usable for resale of Transfer Restricted Securities during the period required by this Agreement, the Company shall file promptly an appropriate amendment to such Registration Statement, in the case of
clause (A), correcting any such misstatement or omission, and, in the case of either clause (A) or (B), use commercially reasonable efforts to cause such amendment to be declared effective and such Registration Statement and the related
Prospectus to become usable for their intended purpose(s) as soon as practicable thereafter; 
 (ii) prepare and
file with the Commission such amendments and post-effective amendments to the applicable Registration Statement as may be necessary to keep the Registration Statement effective for the applicable period set forth in Section 3 or 4 hereof, as
applicable, or such shorter period as will terminate when all Transfer Restricted Securities covered by such Registration Statement have been sold; cause the Prospectus to be supplemented by any required Prospectus supplement, and as so supplemented
to be filed pursuant to Rule 424 under the Securities Act, and to comply fully with the applicable provisions of Rules 424 and 430A under the Securities Act in a timely manner; and comply with the provisions of the Securities Act with respect to the
disposition of all securities covered by such Registration Statement during the applicable period in accordance with the intended method or methods of distribution by the sellers thereof set forth in such Registration Statement or supplement to the
Prospectus; 

  
 -8-

 (iii) in the case of a Shelf Registration Statement, advise the
underwriter(s), if any, and any selling Holders promptly and, if requested by such Persons, to confirm such advice in writing, (A) when the Prospectus or any Prospectus supplement or post-effective amendment has been filed, and, with respect to
any Registration Statement or any post-effective amendment thereto, when the same has become effective, (B) of any request by the Commission for amendments to the Registration Statement or amendments or supplements to the Prospectus or for
additional information relating thereto, (C) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement under the Securities Act or of the suspension by any state securities commission of the
qualification of the Transfer Restricted Securities for offering or sale in any jurisdiction, or the initiation of any proceeding for any of the preceding purposes, (D) of the existence of any fact or the happening of any event that makes any
statement of a material fact made in the Registration Statement, the Prospectus, any amendment or supplement thereto, or any document incorporated by reference therein untrue, or that requires the making of any additions to or changes in the
Registration Statement or the Prospectus in order to make any statement of material fact therein not misleading. If at any time the Commission shall issue any stop order suspending the effectiveness of the Registration Statement, or any state
securities commission or other regulatory authority shall issue an order suspending the qualification or exemption from qualification of the Transfer Restricted Securities under state securities or blue sky laws, each of the Company and the
Guarantors shall use commercially reasonable efforts to obtain the withdrawal or lifting of such order at the earliest possible time; 
 (iv) in the case of a Shelf Registration Statement, furnish without charge to each of the Initial Purchasers, each selling Holder named in any Registration Statement and the underwriter(s), if any, before
filing with the Commission, copies of any Registration Statement or any Prospectus included therein or any amendments or supplements to any such Registration Statement or Prospectus (including all documents incorporated by reference after the
initial filing of such Registration Statement), which documents will be subject to the review and comment of such Holders and underwriter(s), if any, in connection with such sale, if any, for a period of at least five Business Days, and the Company
will not file any such Registration Statement or Prospectus or any amendment or supplement to any such Registration Statement or Prospectus (including all such documents incorporated by reference) to which the Initial Purchasers of Transfer
Restricted Securities covered by such Registration Statement or the underwriter(s), if any, shall reasonably object in writing within five Business Days after the receipt thereof (such objection to be deemed timely made upon confirmation of telecopy
transmission within such period). The objection of the Initial Purchasers or underwriters, if any, shall be deemed to be reasonable if such Registration Statement, amendment, Prospectus or supplement, as applicable, as proposed to be filed, contains
a misstatement or omission of any statement of material fact; 
 (v) make available at reasonable times for
inspection by the Initial Purchasers, the managing underwriter(s), if any, participating in any disposition pursuant to such Registration Statement and any attorney or accountant retained by the Initial Purchasers or any of the underwriter(s), all
financial and other records, pertinent corporate documents and properties of each of the Company and the Guarantors, and cause the 

  
 -9-

 
Company’s and the Guarantors’ officers, directors and employees to supply all information reasonably requested by any such Holder, underwriter, attorney or accountant in connection with
such Registration Statement or any post-effective amendment thereto subsequent to the filing thereof and prior to its effectiveness and to participate in meetings with investors to the extent requested by the managing underwriter(s), if any;

 (vi) in connection with an Underwritten Offering, if requested by any selling Holders or the underwriter(s),
if any, promptly incorporate in any Registration Statement or Prospectus, pursuant to a supplement or post-effective amendment if necessary, such information as such selling Holders and underwriter(s), if any, may reasonably request to have included
therein, including, without limitation, information relating to the “Plan of Distribution” of the Transfer Restricted Securities, information with respect to the principal amount of Transfer Restricted Securities being sold to such
underwriter(s), the purchase price being paid therefor and any other terms of the offering of the Transfer Restricted Securities to be sold in such offering; and make all required filings of such Prospectus supplement or post-effective amendment as
soon as practicable after the Company is notified of the matters to be incorporated in such Prospectus supplement or post-effective amendment; 
 (vii) cause the Transfer Restricted Securities covered by the Registration Statement to be rated with the appropriate rating agencies, if so requested by the Holders of a majority in aggregate principal
amount of Securities covered thereby or the underwriter(s), if any; 
 (viii) furnish to each Initial Purchaser,
each selling Holder and each of the underwriter(s), if any, without charge, at least one copy of the Registration Statement, as first filed with the Commission, and of each amendment thereto, excluding all documents incorporated by reference therein
and all exhibits thereto; 
 (ix) in the case of a Shelf Registration Statement, deliver to each selling Holder
and each of the underwriter(s), if any, without charge, as many copies of the Prospectus (including each preliminary prospectus) and any amendment or supplement thereto as such Persons reasonably may request; each of the Company and the Guarantors
hereby consents to the use of the Prospectus and any amendment or supplement thereto by each of the selling Holders and each of the underwriter(s), if any, in connection with the offering and the sale of the Transfer Restricted Securities covered by
the Prospectus or any amendment or supplement thereto; 
 (x) enter into such agreements (including an
underwriting agreement), and make such representations and warranties, and take all such other actions in connection therewith in order to expedite or facilitate the disposition of the Transfer Restricted Securities pursuant to any Shelf
Registration Statement contemplated by this Agreement, all to such extent as may be reasonably requested by any Initial Purchaser or by any Holder of Transfer Restricted Securities or underwriter in connection with any sale or resale pursuant to any
Shelf Registration Statement contemplated by this Agreement; and if an underwriting agreement is entered into and the registration is an Underwritten Registration, each of the Company and the Guarantors shall: 

  
 -10-

 (A) furnish to each Initial Purchaser, each selling Holder and each
underwriter, if any, in such substance and scope as they may request and as are customarily made by issuers to underwriters in primary underwritten offerings, upon the effectiveness of the Shelf Registration Statement: 

(1) a certificate, dated the date of effectiveness of the Shelf Registration Statement, signed by (y) the President
or any Vice President and (z) a principal financial or accounting officer of each of the Company and the Guarantors, confirming, as of the date thereof, the matters set forth in paragraphs (i), (ii) and (iii) of Section 5(e) of
the Purchase Agreement and such other matters as such parties may reasonably request; 
 (2) an opinion, dated
the date of effectiveness of the Shelf Registration Statement, of counsel for the Company and the Guarantors, covering the matters set forth in Section 5(c) of the Purchase Agreement and such other matter as such parties may reasonably request,
and in any event including a statement to the effect that such counsel has participated in conferences with officers and other representatives of the Company, representatives of the independent public accountants for the Company, representatives of
the underwriter(s), if any, and counsel to the underwriter(s), if any, in connection with the preparation of such Registration Statement and the related Prospectus and have considered the matters required to be stated therein and the statements
contained therein, although such counsel has not independently verified the accuracy, completeness or fairness of such statements; and that such counsel advises that, on the basis of the foregoing, no facts came to such counsel’s attention that
caused such counsel to believe that the applicable Registration Statement, at the time such Registration Statement or any post-effective amendment thereto became effective, contained an untrue statement of a material fact or omitted to state a
material fact required to be stated therein or necessary to make the statements therein not misleading, or that the Prospectus contained in such Registration Statement as of its date, contained an untrue statement of a material fact or omitted to
state a material fact necessary in order to make the statements therein not misleading. Without limiting the foregoing, such counsel may state further that such counsel assumes no responsibility for, and has not independently verified, the accuracy,
completeness or fairness of the financial statements, notes and schedules and other financial data included in any Registration Statement contemplated by this Agreement or the related Prospectus; and 

(3) a customary comfort letter, dated the date of effectiveness of the Shelf Registration Statement, from the
Company’s independent accountants, in the customary form and covering matters of the type customarily requested to be covered in comfort letters by underwriters in connection with primary underwritten offerings, and covering or affirming the
matters set forth in the comfort letters delivered pursuant to Section 5(a) of the Purchase Agreement, without exception; 

  
 -11-

 (B) set forth in full or incorporate by reference in the underwriting
agreement, if any, the indemnification provisions and procedures of Section 8 hereof with respect to all parties to be indemnified pursuant to said Section; and

with Section 6(c)(x)(A) hereof and with any customary conditions contained in the underwriting agreement or other agreement entered into by the Company or any of the Guarantors pursuant to this Section 6(c)(x), if any. 

If at any time the representations and warranties of the Company and the Guarantors contemplated in
Section 6(c)(x)(A)(1) hereof cease to be true and correct, the Company or the Guarantors shall so advise the Initial Purchasers and the underwriter(s), if any, and each selling Holder promptly and, if requested by such Persons, shall confirm
such advice in writing; 
 (xi) prior to any public offering of Transfer Restricted Securities, cooperate with
the selling Holders, the underwriter(s), if any, and their respective counsel in connection with the registration and qualification of the Transfer Restricted Securities under the state securities or blue sky laws of such jurisdictions as the
selling Holders or underwriter(s), if any, may request and do any and all other acts or things necessary or advisable to enable the disposition in such jurisdictions of the Transfer Restricted Securities covered by the Shelf Registration Statement;
provided, however, that none of the Company or the Guarantors shall be required to register or qualify as a foreign corporation where it is not then so qualified or to take any action that would subject it to the service of process in suits
or to taxation, other than as to matters and transactions relating to the Registration Statement, in any jurisdiction where it is not then so subject; 
 (xii) shall issue, upon the request of any Holder of Initial Securities covered by the Shelf Registration Statement, Exchange Securities having an aggregate principal amount equal to the aggregate

(xv) if any fact or event contemplated by Section 6(c)(iii)(D) hereof shall exist or have occurred, prepare a
supplement or post-effective amendment to the Registration Statement or related Prospectus or any document incorporated therein by reference or file any other required document so that, as thereafter delivered to the purchasers of Transfer

 Each Holder agrees by acquisition of a Transfer Restricted Security that, upon receipt of
any notice from the Company of the existence of any fact of the kind described in Section 6(c)(iii)(D) hereof, such Holder will forthwith discontinue disposition of Transfer Restricted Securities pursuant to the applicable Registration
Statement until such Holder’s receipt of the copies of the supplemented or amended Prospectus contemplated by Section 6(c)(xv) hereof, or until it is advised in writing (the “Advice”) by the Company that the use of the Prospectus
may be resumed, and has received copies of any additional or supplemental filings that are incorporated by reference in the Prospectus. If so directed by the Company, each Holder will deliver to the Company (at the Company’s expense) all
copies, other than permanent file copies then in such Holder’s possession, of the Prospectus covering such Transfer Restricted Securities that was current at the time of receipt of such notice. In the event the Company shall give any such
notice, the time period regarding the effectiveness of such Registration Statement set forth in Section 3 or 4 hereof, as applicable, shall be extended by the number of days during the period from and including the date of the giving of such
notice pursuant to Section 6(c)(iii)(D) hereof to and including the date when each selling Holder covered by such Registration Statement shall have received the copies of the supplemented or amended Prospectus contemplated by
Section 6(c)(xv) hereof or shall have received the Advice; provided, however, that no such extension shall be taken into account in determining whether Additional Interest is due pursuant to Section 5 hereof or the amount of such
Additional Interest, it being agreed that the Company’s option to suspend use of a Registration Statement pursuant to this paragraph shall be treated as a Registration Default for purposes of Section 5 hereof. 

SECTION 7. Registration Expenses. 
 (a) All expenses incident to the Company’s and the Guarantors’ performance of or compliance with this Agreement will be borne by the Company and the Guarantors, jointly and severally, regardless
of whether a Registration Statement becomes effective, including, without limitation: (i) all registration and filing fees and expenses (including filings made by any Initial Purchaser or Holder with FINRA (and, if applicable, the fees and
expenses of any “qualified independent underwriter” and its counsel that may be required by the rules and regulations of FINRA)); (ii) all fees and expenses of compliance with federal securities and state securities or blue sky laws;
(iii) all expenses of printing (including printing certificates for the Exchange Securities to be issued in the Exchange Offer and printing of Prospectuses), messenger and delivery services and telephone; (iv) all fees and disbursements of
counsel for the Company, the Guarantors and, subject to Section 7(b) hereof, the Holders of Transfer Restricted Securities; (v) all application and filing fees in connection with listing the Exchange Securities on a securities exchange or
automated quotation system pursuant to the requirements thereof; and (vi) all fees and disbursements of independent certified public accountants of the Company and the Guarantors (including the expenses of any special audit and comfort letters
required by or incident to such performance). 
 Each of the Company and the Guarantors will, in any event, bear its internal
expenses (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties), the expenses of any annual audit and the fees and expenses of any Person, including special experts, retained by
the Company or the Guarantors. 

  
 -14-

 (b) In connection with any Registration Statement required by this Agreement (including,
without limitation, the Exchange Offer Registration Statement and the Shelf Registration Statement), the Company and the Guarantors, jointly and severally, will reimburse the Initial Purchasers and the Holders of Transfer Restricted Securities being
tendered in the Exchange Offer and/or resold pursuant to the “Plan of Distribution” contained in the Exchange Offer Registration Statement or registered pursuant to the Shelf Registration Statement, as applicable, for the reasonable fees
and disbursements of not more than one counsel, who shall be Cahill Gordon & Reindel LLP or such other counsel as may be chosen by the Holders of a majority in principal amount of the Transfer Restricted Securities for whose benefit such
Registration Statement is being prepared. 
 SECTION 8. Indemnification. 

(a) The Company and the Guarantors, jointly and severally, agree to indemnify and hold harmless (i) each Holder and (ii) each
Person, if any, who controls (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) any Holder (any of the Persons referred to in this clause (ii) being hereinafter referred to as a
“controlling person”) and (iii) the respective officers, directors, partners, employees, representatives and agents of any Holder or any controlling person (any Person referred to in clause (i), (ii) or (iii) may hereinafter
be referred to as an “Indemnified Holder”), to the fullest extent lawful, from and against any and all losses, claims, damages, liabilities, judgments, actions and expenses (including, without limitation, and as incurred, reimbursement of
all reasonable costs of investigating, preparing, pursuing, settling, compromising, paying or defending any claim or action, or any investigation or proceeding by any governmental agency or body, commenced or threatened, including the reasonable
fees and expenses of counsel to any Indemnified Holder), joint or several, directly or indirectly caused by, related to, based upon, arising out of or in connection with any untrue statement or alleged untrue statement of a material fact contained
in any Registration Statement or Prospectus (or any amendment or supplement thereto), or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading,
except insofar as such losses, claims, damages, liabilities or expenses are caused by an untrue statement or omission or alleged untrue statement or omission that is made in reliance upon and in conformity with information relating to any of the
Holders furnished in writing to the Company by any of the Holders expressly for use therein. This indemnity agreement shall be in addition to any liability which the Company or any of the Guarantors may otherwise have. 

In case any action or proceeding (including any governmental or regulatory investigation or proceeding) shall be brought or asserted
against any of the Indemnified Holders with respect to which indemnity may be sought against the Company or the Guarantors, such Indemnified Holder (or the Indemnified Holder controlled by such controlling person) shall promptly notify the Company
and the Guarantors in writing; provided, however, that the failure to give such notice shall not relieve any of the Company or the Guarantors of its obligations pursuant to this Agreement to the extent it is not materially prejudiced (through
the forfeiture of substantive rights and defenses) as a result of such failure. Such Indemnified Holder shall have the right to employ its own counsel in any such action and the fees and expenses of such counsel shall be paid, as incurred, by the
Company and the Guarantors (regardless of whether it is ultimately determined that an Indemnified Holder is not entitled to indemnification hereunder). The Company and the Guarantors shall not, in connection with any one such action or proceeding or
separate 

  
 -15-

 
but substantially similar or related actions or proceedings in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses
of more than one separate firm of attorneys (in addition to any local counsel) at any time for such Indemnified Holders, which firm shall be designated by the Holders. The Company and the Guarantors shall be liable for any settlement of any such
action or proceeding effected with the Company’s and the Guarantors’ prior written consent, which consent shall not be withheld unreasonably, and each of the Company and the Guarantors agrees to indemnify and hold harmless any Indemnified
Holder from and against any loss, claim, damage, liability or expense by reason of any settlement of any action effected with the written consent of the Company and the Guarantors. The Company and the Guarantors shall not, without the prior written
consent of each Indemnified Holder, settle or compromise or consent to the entry of judgment in or otherwise seek to terminate any pending or threatened action, claim, litigation or proceeding in respect of which indemnification or contribution may
be sought hereunder (whether or not any Indemnified Holder is a party thereto), unless such settlement, compromise, consent or termination includes an unconditional release of each Indemnified Holder from all liability arising out of such action,
claim, litigation or proceeding. 
 (b) Each Holder of Transfer Restricted Securities agrees, severally and not jointly, to
indemnify and hold harmless the Company, the Guarantors and their respective directors and officers of the Company and the Guarantors who sign a Registration Statement, and any Person controlling (within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act) the Company or any of the Guarantors, and the respective officers, directors, partners, employees, representatives and agents of each such Person, to the same extent as the foregoing indemnity
from the Company and the Guarantors to each of the Indemnified Holders, but only with respect to claims and actions based on information relating to such Holder furnished in writing by such Holder expressly for use in any Registration Statement. In
case any action or proceeding shall be brought against the Company, the Guarantors or their respective directors or officers or any such controlling person in respect of which indemnity may be sought against a Holder of Transfer Restricted
Securities, such Holder shall have the rights and duties given the Company and the Guarantors, and the Company, the Guarantors, their respective directors and officers and such controlling person shall have the rights and duties given to each Holder
by the preceding paragraph. 
 (c) If the indemnification provided for in this Section 8 is unavailable to an indemnified
party under Section 8(a) or (b) hereof (other than by reason of exceptions provided in those Sections) in respect of any losses, claims, damages, liabilities, judgments, actions or expenses referred to therein, then each applicable
indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities or expenses in such proportion as is appropriate to
reflect the relative benefits received by the Company and the Guarantors, on the one hand, and the Holders, on the other hand, from the Initial Placement (which in the case of the Company and the Guarantors shall be deemed to be equal to the total
gross proceeds to the Company and the Guarantors from the Initial Placement), the amount of Additional Interest which did not become payable as a result of the filing of the Registration Statement resulting in such losses, claims, damages,
liabilities, judgments actions or expenses, or if such allocation is not permitted by applicable law, the relative fault of the Company and the Guarantors, on the one hand, and the Holders, on the other hand, in connection with the statements or
omissions which resulted in such losses, 

  
 -16-

 
claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative fault of the Company on the one hand and of the Indemnified Holder on the other
shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or any of the
Guarantors, on the one hand, or the Indemnified Holders, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a
party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in the second paragraph of Section 8(a) hereof, any legal or other fees or expenses
reasonably incurred by such party in connection with investigating or defending any action or claim. 
 The Company, the
Guarantors and each Holder of Transfer Restricted Securities agree that it would not be just and equitable if contribution pursuant to this Section 8(c) were determined by pro rata allocation (even if the Holders were treated as one entity for
such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an indemnified party as a result of the losses, claims,
damages, liabilities or expenses referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8, none of the Holders (and its related Indemnified Holders) shall be required to contribute, in the aggregate, any amount in excess of the
amount by which the total discount received by such Holder with respect to the Initial Securities exceeds the amount of any damages which such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission
or alleged omission. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. The
Holders’ obligations to contribute pursuant to this Section 8(c) are several in proportion to the respective principal amount of Initial Securities held by each of the Holders hereunder and not joint. 

SECTION 9. Rule 144A. Each of the Company and the Guarantors hereby agrees with each Holder, for so long as any Transfer
Restricted Securities remain outstanding, to make available to any Holder or beneficial owner of Transfer Restricted Securities, upon their request in connection with any sale thereof to any prospective purchaser of such Transfer Restricted
Securities from such Holder or beneficial owner, the information required by Rule 144A(d)(4) under the Securities Act in order to permit resales of such Transfer Restricted Securities pursuant to Rule 144A under the Securities Act. 

SECTION 10. Participation in Underwritten Registrations. No Holder may participate in any Underwritten Registration hereunder
unless such Holder (a) agrees to sell such Holder’s Transfer Restricted Securities on the basis provided in any underwriting arrangements approved by the Persons entitled hereunder to approve such arrangements and (b) completes and
executes all reasonable questionnaires, powers of attorney, indemnities, underwriting agreements, lock-up letters and other documents required under the terms of such underwriting arrangements. 

  
 -17-

 SECTION 11. Selection of Underwriters. The Holders of Transfer Restricted
Securities covered by the Shelf Registration Statement who desire to do so may sell such Transfer Restricted Securities in an Underwritten Offering. In any such Underwritten Offering, the investment banker(s) and managing underwriter(s) that will
administer such offering will be selected by the Holders of a majority in aggregate principal amount of the Transfer Restricted Securities included in such offering; provided, however, that such investment banker(s) and managing
underwriter(s) must be reasonably satisfactory to the Company. 
 SECTION 12. Miscellaneous. 

(a) Remedies. Each of the Company and the Guarantors hereby agrees that monetary damages would not be adequate compensation for
any loss incurred by reason of a breach by it of the provisions of this Agreement and hereby agree to waive the defense in any action for specific performance that a remedy at law would be adequate. 

(b) No Inconsistent Agreements. Each of the Company and the Guarantors will not on or after the date of this Agreement enter into
any agreement with respect to its securities that is inconsistent with the rights granted to the Holders in this Agreement or otherwise conflicts with the provisions hereof. The rights granted to the Holders hereunder do not in any way conflict with
and are not inconsistent with the rights granted to the holders of the Company’s or any of the Guarantors’ securities under any agreement in effect on the date hereof. 

(c) Adjustments Affecting the Securities. The Company will not take any action, or permit any change to occur, with respect to the
Securities that would materially and adversely affect the ability of the Holders to Consummate any Exchange Offer. 
 (d)
Amendments and Waivers. The provisions of this Agreement may not be amended, modified or supplemented, and waivers or consents to or departures from the provisions hereof may not be given unless the Company has (i) in the case of
Section 5 hereof and this Section 12(d)(i), obtained the written consent of Holders of all outstanding Transfer Restricted Securities and (ii) in the case of all other provisions hereof, obtained the written consent of Holders of a
majority of the outstanding principal amount of Transfer Restricted Securities (excluding any Transfer Restricted Securities held by the Company or its Affiliates). Notwithstanding the foregoing, a waiver or consent to departure from the provisions
hereof that relates exclusively to the rights of Holders whose securities are being tendered pursuant to the Exchange Offer and that does not affect directly or indirectly the rights of other Holders whose securities are not being tendered pursuant
to such Exchange Offer may be given by the Holders of a majority of the outstanding principal amount of Transfer Restricted Securities being tendered or registered; provided, however, that, with respect to any matter that directly or
indirectly affects the rights of any Initial Purchaser hereunder, the Company shall obtain the written consent of each such Initial Purchaser with respect to which such amendment, qualification, supplement, waiver, consent or departure is to be
effective. 
 (e) Notices. All notices and other communications provided for or permitted hereunder shall be made in

shall be in form and substance satisfactory to Agent. 
 3. Representations and Warranties. Borrower represents and
warrants as follows: 
 (a) Authority. Borrower has the requisite corporate power and authority to execute and deliver
this Amendment, and to perform its obligations hereunder and under the Loan Documents (as amended or modified hereby) to which it is a party. The execution, delivery and performance by Borrower of this Amendment have been duly approved by all
necessary corporate action and no other corporate proceedings are necessary to consummate such transactions. 

  
 3 

 (b) Enforceability. This Amendment has been duly executed and delivered by Borrower.
This Amendment and each Loan Document to which Borrower is a party (as amended or modified hereby) is the legal, valid and binding obligation of Borrower, enforceable against Borrower in accordance with its terms, and is in full force and effect.

 (c) Representations and Warranties. The representations and warranties contained in each Loan Document to which
Borrower is a party (other than any such representations or warranties that, by their terms, are specifically made as of a date other than the date hereof) are correct on and as of the date hereof as though made on and as of the date hereof.

 (d) Due Execution. The execution, delivery and performance of this Amendment are within the power of Borrower, have
been duly authorized by all necessary corporate action, have received all necessary governmental approval, if any, and do not contravene any law or any contractual restrictions binding on Borrower. 

(e) No Default. No event has occurred and is continuing that constitutes an Event of Default. 

4. Choice of Law. The validity of this Amendment, its construction, interpretation and enforcement, the rights of the parties
hereunder, shall be determined under, governed by, and construed in accordance with the internal laws of the State of California, without giving effect to any conflict of law principles (but giving effect to Federal laws relating to national banks).
The consent to forum and arbitration provisions set forth in Section 14.15 of the Loan Agreement are hereby incorporated in this Amendment by reference. 
 5. Counterparts. This Amendment may be executed in any number of counterparts and by different parties and separate counterparts, each of which when so executed and delivered, shall be deemed an
original, and all of which, when taken together, shall constitute one and the same instrument. Delivery of an executed counterpart of a signature page to this Amendment by telefacsimile or a substantially similar electronic transmission shall have
the same force and effect as the delivery of an original executed counterpart of this Amendment. Any party delivering an executed counterpart of this Amendment by telefacsimile or a substantially similar electronic transmission shall also deliver an
original executed counterpart, but the failure to do so shall not affect the validity, enforceability or binding effect of such agreement. 
 6. Reference to and Effect on the Loan Documents. 
 (a) Upon and after the
effectiveness of this Amendment, each reference in the Loan Agreement to “this Agreement”, “hereunder”, “hereof” or words of like import referring to the Loan Agreement, and each reference in the other Loan Documents to
“the Loan Agreement”, “thereof” or words of like import referring to the Loan Agreement, shall mean and be a reference to the Loan Agreement as modified and amended hereby. 

(b) Except as specifically amended above, the Loan Agreement and all other Loan Documents are and shall continue to be in full force and
effect and are hereby in all respects ratified and confirmed and shall constitute the legal, valid, binding and enforceable obligations of Borrower to Agent and the Lenders. 
 (c) The execution, delivery and effectiveness of this Amendment shall not, except as expressly provided herein, operate as a waiver of any right, power or remedy of Agent or any Lender under any of the
Loan Documents, nor constitute a waiver of any provision of any of the Loan Documents. 
 (d) To the extent that any terms and
conditions in any of the Loan Documents shall contradict or be in conflict with any terms or conditions of the Loan Agreement, after giving effect to this 

  
 4 

 
Amendment, such terms and conditions are hereby deemed modified or amended accordingly to reflect the terms and conditions of the Loan Agreement as modified or amended hereby. 

7. Ratification. Borrower hereby restates, ratifies and reaffirms each and every term and condition set forth in the Loan
Agreement, as amended hereby, and the Loan Documents effective as of the date hereof. 
 8. Estoppel. To induce Lenders to
enter into this Amendment and to continue to make advances to Borrower under the Loan Agreement, Borrower hereby acknowledges and agrees that, as of the date hereof, there exists no right of offset, defense, counterclaim or objection in favor of
Borrower as against Agent or any Lender with respect to the Obligations. 
 9. Integration. This Amendment, together with
the other Loan Documents, incorporates all negotiations of the parties hereto with respect to the subject matter hereof and is the final expression and agreement of the parties hereto with respect to the subject matter hereof. 

10. Severability. In case any provision in this Amendment shall be invalid, illegal or unenforceable, such provision shall be
severable from the remainder of this Amendment and the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.
